SECTION IV. Of the Impossibility of an Ontological Proof of
the Existence of God.
It is evident from what has been said that the conception of an
absolutely necessary being is a mere idea, the objective reality of
which is far from being established by the mere fact that it is a need
of reason. On the contrary, this idea serves merely to indicate a
certain unattainable perfection, and rather limits the operations
than, by the presentation of new objects, extends the sphere of the
understanding. But a strange anomaly meets us at the very threshold;
for the inference from a given existence in general to an absolutely
necessary existence seems to be correct and unavoidable, while the
conditions of the understanding refuse to aid us in forming any
conception of such a being.
Philosophers have always talked of an absolutely necessary being,
and have nevertheless declined to take the trouble of conceiving
whether- and how- a being of this nature is even cogitable, not to
mention that its existence is actually demonstrable. A verbal
definition of the conception is certainly easy enough: it is something
the non-existence of which is impossible. But does this definition
throw any light upon the conditions which render it impossible to
cogitate the non-existence of a thing- conditions which we wish to
ascertain, that we may discover whether we think anything in the
conception of such a being or not? For the mere fact that I throw
away, by means of the word unconditioned, all the conditions which the
understanding habitually requires in order to regard anything as
necessary, is very far from making clear whether by means of the
conception of the unconditionally necessary I think of something, or
really of nothing at all.
Nay, more, this chance-conception, now become so current, many
have endeavoured to explain by examples which seemed to render any
inquiries regarding its intelligibility quite needless. Every
geometrical proposition- a triangle has three angles- it was said,
is absolutely necessary; and thus people talked of an object which lay
out of the sphere of our understanding as if it were perfectly plain
what the conception of such a being meant.
All the examples adduced have been drawn, without exception, from
judgements, and not from things. But the unconditioned necessity of
a judgement does not form the absolute necessity of a thing. On the
contrary, the absolute necessity of a judgement is only a
conditioned necessity of a thing, or of the predicate in a
judgement. The proposition above-mentioned does not enounce that three
angles necessarily exist, but, upon condition that a triangle
exists, three angles must necessarily exist- in it. And thus this
logical necessity has been the source of the greatest delusions.
Having formed an a priori conception of a thing, the content of
which was made to embrace existence, we believed ourselves safe in
concluding that, because existence belongs necessarily to the object
of the conception (that is, under the condition of my positing this
thing as given), the existence of the thing is also posited
necessarily, and that it is therefore absolutely necessary- merely
because its existence has been cogitated in the conception.
If, in an identical judgement, I annihilate the predicate in
thought, and retain the subject, a contradiction is the result; and
hence I say, the former belongs necessarily to the latter. But if I
suppress both subject and predicate in thought, no contradiction
arises; for there is nothing at all, and therefore no means of forming
a contradiction. To suppose the existence of a triangle and not that
of its three angles, is self-contradictory; but to suppose the
non-existence of both triangle and angles is perfectly admissible. And
so is it with the conception of an absolutely necessary being.
Annihilate its existence in thought, and you annihilate the thing
itself with all its predicates; how then can there be any room for
contradiction? Externally, there is nothing to give rise to a
contradiction, for a thing cannot be necessary externally; nor
internally, for, by the annihilation or suppression of the thing
itself, its internal properties are also annihilated. God is
omnipotent- that is a necessary judgement. His omnipotence cannot be
denied, if the existence of a Deity is posited- the existence, that
is, of an infinite being, the two conceptions being identical. But
when you say, God does not exist, neither omnipotence nor any other
predicate is affirmed; they must all disappear with the subject, and
in this judgement there cannot exist the least self-contradiction.
You have thus seen that when the predicate of a judgement is
annihilated in thought along with the subject, no internal
contradiction can arise, be the predicate what it may. There is no
possibility of evading the conclusion- you find yourselves compelled
to declare: There are certain subjects which cannot be annihilated
in thought. But this is nothing more than saying: There exist subjects
which are absolutely necessary- the very hypothesis which you are
called upon to establish. For I find myself unable to form the
slightest conception of a thing which when annihilated in thought with
all its predicates, leaves behind a contradiction; and contradiction
is the only criterion of impossibility in the sphere of pure a
priori conceptions.
Against these general considerations, the justice of which no one
can dispute, one argument is adduced, which is regarded as
furnishing a satisfactory demonstration from the fact. It is
affirmed that there is one and only one conception, in which the
non-being or annihilation of the object is self-contradictory, and
this is the conception of an ens realissimum. It possesses, you say,
all reality, and you feel yourselves justified in admitting the
possibility of such a being. (This I am willing to grant for the
present, although the existence of a conception which is not
self-contradictory is far from being sufficient to prove the
possibility of an object.)* Now the notion of all reality embraces
in it that of existence; the notion of existence lies, therefore, in
the conception of this possible thing. If this thing is annihilated in
thought, the internal possibility of the thing is also annihilated,
which is self-contradictory.
*A conception is always possible, if it is not self-contradictory.
This is the logical criterion of possibility, distinguishing the
object of such a conception from the nihil negativum. But it may be,
notwithstanding, an empty conception, unless the objective reality
of this synthesis, but which it is generated, is demonstrated; and a
proof of this kind must be based upon principles of possible
experience, and not upon the principle of analysis or contradiction.
This remark may be serviceable as a warning against concluding, from
the possibility of a conception- which is logical- the possibility
of a thing- which is real.
I answer: It is absurd to introduce- under whatever term
disguised- into the conception of a thing, which is to be cogitated
solely in reference to its possibility, the conception of its
existence. If this is admitted, you will have apparently gained the
day, but in reality have enounced nothing but a mere tautology. I ask,
is the proposition, this or that thing (which I am admitting to be
possible) exists, an analytical or a synthetical proposition? If the
former, there is no addition made to the subject of your thought by
the affirmation of its existence; but then the conception in your
minds is identical with the thing itself, or you have supposed the
existence of a thing to be possible, and then inferred its existence
from its internal possibility- which is but a miserable tautology. The
word reality in the conception of the thing, and the word existence in
the conception of the predicate, will not help you out of the
difficulty. For, supposing you were to term all positing of a thing
reality, you have thereby posited the thing with all its predicates in
the conception of the subject and assumed its actual existence, and
this you merely repeat in the predicate. But if you confess, as
every reasonable person must, that every existential proposition is
synthetical, how can it be maintained that the predicate of
existence cannot be denied without contradiction?- a property which is
the characteristic of analytical propositions, alone.
I should have a reasonable hope of putting an end for ever to this
sophistical mode of argumentation, by a strict definition of the
conception of existence, did not my own experience teach me that the
illusion arising from our confounding a logical with a real
predicate (a predicate which aids in the determination of a thing)
resists almost all the endeavours of explanation and illustration. A
logical predicate may be what you please, even the subject may be
predicated of itself; for logic pays no regard to the content of a
judgement. But the determination of a conception is a predicate, which
adds to and enlarges the conception. It must not, therefore, be
contained in the conception.
Being is evidently not a real predicate, that is, a conception of
something which is added to the conception of some other thing. It
is merely the positing of a thing, or of certain determinations in it.
Logically, it is merely the copula of a judgement. The proposition,
God is omnipotent, contains two conceptions, which have a certain
object or content; the word is, is no additional predicate- it
merely indicates the relation of the predicate to the subject. Now, if
I take the subject (God) with all its predicates (omnipotence being
one), and say: God is, or, There is a God, I add no new predicate to
the conception of God, I merely posit or affirm the existence of the
subject with all its predicates- I posit the object in relation to
my conception. The content of both is the same; and there is no
addition made to the conception, which expresses merely the
possibility of the object, by my cogitating the object- in the
expression, it is- as absolutely given or existing. Thus the real
contains no more than the possible. A hundred real dollars contain
no more than a hundred possible dollars. For, as the latter indicate
the conception, and the former the object, on the supposition that the
content of the former was greater than that of the latter, my
conception would not be an expression of the whole object, and would
consequently be an inadequate conception of it. But in reckoning my
wealth there may be said to be more in a hundred real dollars than
in a hundred possible dollars- that is, in the mere conception of
them. For the real object- the dollars- is not analytically
contained in my conception, but forms a synthetical addition to my
conception (which is merely a determination of my mental state),
although this objective reality- this existence- apart from my
conceptions, does not in the least degree increase the aforesaid
hundred dollars.
By whatever and by whatever number of predicates- even to the
complete determination of it- I may cogitate a thing, I do not in
the least augment the object of my conception by the addition of the
statement: This thing exists. Otherwise, not exactly the same, but
something more than what was cogitated in my conception, would
exist, and I could not affirm that the exact object of my conception
had real existence. If I cogitate a thing as containing all modes of
reality except one, the mode of reality which is absent is not added
to the conception of the thing by the affirmation that the thing
exists; on the contrary, the thing exists- if it exist at all- with
the same defect as that cogitated in its conception; otherwise not
that which was cogitated, but something different, exists. Now, if I
cogitate a being as the highest reality, without defect or
imperfection, the question still remains- whether this being exists or
not? For, although no element is wanting in the possible real
content of my conception, there is a defect in its relation to my
mental state, that is, I am ignorant whether the cognition of the
object indicated by the conception is possible a posteriori. And
here the cause of the present difficulty becomes apparent. If the
question regarded an object of sense merely, it would be impossible
for me to confound the conception with the existence of a thing. For
the conception merely enables me to cogitate an object as according
with the general conditions of experience; while the existence of
the object permits me to cogitate it as contained in the sphere of
actual experience. At the same time, this connection with the world of
experience does not in the least augment the conception, although a
possible perception has been added to the experience of the mind.
But if we cogitate existence by the pure category alone, it is not
to be wondered at, that we should find ourselves unable to present any
criterion sufficient to distinguish it from mere possibility.
Whatever be the content of our conception of an object, it is
necessary to go beyond it, if we wish to predicate existence of the
object. In the case of sensuous objects, this is attained by their
connection according to empirical laws with some one of my
perceptions; but there is no means of cognizing the existence of
objects of pure thought, because it must be cognized completely a
priori. But all our knowledge of existence (be it immediately by
perception, or by inferences connecting some object with a perception)
belongs entirely to the sphere of experience- which is in perfect
unity with itself; and although an existence out of this sphere cannot
be absolutely declared to be impossible, it is a hypothesis the
truth of which we have no means of ascertaining.
The notion of a Supreme Being is in many respects a highly useful
idea; but for the very reason that it is an idea, it is incapable of
enlarging our cognition with regard to the existence of things. It
is not even sufficient to instruct us as to the possibility of a being
which we do not know to exist. The analytical criterion of
possibility, which consists in the absence of contradiction in
propositions, cannot be denied it. But the connection of real
properties in a thing is a synthesis of the possibility of which an
a priori judgement cannot be formed, because these realities are not
presented to us specifically; and even if this were to happen, a
judgement would still be impossible, because the criterion of the
possibility of synthetical cognitions must be sought for in the
world of experience, to which the object of an idea cannot belong. And
thus the celebrated Leibnitz has utterly failed in his attempt to
establish upon a priori grounds the possibility of this sublime
ideal being.
The celebrated ontological or Cartesian argument for the existence
of a Supreme Being is therefore insufficient; and we may as well
hope to increase our stock of knowledge by the aid of mere ideas, as
the merchant to augment his wealth by the addition of noughts to his
cash account.
SECTION V. Of the Impossibility of a Cosmological Proof
of the Existence of God.
It was by no means a natural course of proceeding, but, on the
contrary, an invention entirely due to the subtlety of the schools, to
attempt to draw from a mere idea a proof of the existence of an object
corresponding to it. Such a course would never have been pursued, were
it not for that need of reason which requires it to suppose the
existence of a necessary being as a basis for the empirical regress,
and that, as this necessity must be unconditioned and a priori, reason
is bound to discover a conception which shall satisfy, if possible,
this requirement, and enable us to attain to the a priori cognition of
such a being. This conception was thought to be found in the idea of
an ens realissimum, and thus this idea was employed for the attainment
of a better defined knowledge of a necessary being, of the existence
of which we were convinced, or persuaded, on other grounds. Thus
reason was seduced from her natural courage; and, instead of
concluding with the conception of an ens realissimum, an attempt was
made to begin with it, for the purpose of inferring from it that
idea of a necessary existence which it was in fact called in to
complete. Thus arose that unfortunate ontological argument, which
neither satisfies the healthy common sense of humanity, nor sustains
the scientific examination of the philosopher.
The cosmological proof, which we are about to examine, retains the
connection between absolute necessity and the highest reality; but,
instead of reasoning from this highest reality to a necessary
existence, like the preceding argument, it concludes from the given.
unconditioned necessity of some being its unlimited reality. The track
it pursues, whether rational or sophistical, is at least natural,
and not only goes far to persuade the common understanding, but
shows itself deserving of respect from the speculative intellect;
while it contains, at the same time, the outlines of all the arguments
employed in natural theology- arguments which always have been, and
still will be, in use and authority. These, however adorned, and hid
under whatever embellishments of rhetoric and sentiment, are at bottom
identical with the arguments we are at present to discuss. This proof,
termed by Leibnitz the argumentum a contingentia mundi, I shall now
lay before the reader, and subject to a strict examination.
It is framed in the following manner: If something exists, an
absolutely necessary being must likewise exist. Now I, at least,
exist. Consequently, there exists an absolutely necessary being. The
minor contains an experience, the major reasons from a general
experience to the existence of a necessary being.* Thus this
argument really begins at experience, and is not completely a
priori, or ontological. The object of all possible experience being
the world, it is called the cosmological proof. It contains no
reference to any peculiar property of sensuous objects, by which
this world of sense might be distinguished from other possible worlds;
and in this respect it differs from the physico-theological proof,
which is based upon the consideration of the peculiar constitution
of our sensuous world.
*This inference is too well known to require more detailed
discussion. It is based upon the spurious transcendental law of
causality, that everything which is contingent has a cause, which,
if itself contingent, must also have a cause; and so on, till the
series of subordinated causes must end with an absolutely necessary
cause, without which it would not possess completeness.
The proof proceeds thus: A necessary being can be determined only in
one way, that is, it can be determined by only one of all possible
opposed predicates; consequently, it must be completely determined
in and by its conception. But there is only a single conception of a
thing possible, which completely determines the thing a priori: that
is, the conception of the ens realissimum. It follows that the
conception of the ens realissimum is the only conception by and in
which we can cogitate a necessary being. Consequently, a Supreme Being
necessarily exists.
In this cosmological argument are assembled so many sophistical
propositions that speculative reason seems to have exerted in it all
her dialectical skill to produce a transcendental illusion of the most
extreme character. We shall postpone an investigation of this argument
for the present, and confine ourselves to exposing the stratagem by
which it imposes upon us an old argument in a new dress, and appeals
to the agreement of two witnesses, the one with the credentials of
pure reason, and the other with those of empiricism; while, in fact,
it is only the former who has changed his dress and voice, for the
purpose of passing himself off for an additional witness. That it
may possess a secure foundation, it bases its conclusions upon
experience, and thus appears to be completely distinct from the
ontological argument, which places its confidence entirely in pure a
priori conceptions. But this experience merely aids reason in making
one step- to the existence of a necessary being. What the properties
of this being are cannot be learned from experience; and therefore
reason abandons it altogether, and pursues its inquiries in the sphere
of pure conception, for the purpose of discovering what the properties
of an absolutely necessary being ought to be, that is, what among
all possible things contain the conditions (requisita) of absolute
necessity. Reason believes that it has discovered these requisites
in the conception of an ens realissimum- and in it alone, and hence
concludes: The ens realissimum is an absolutely necessary being. But
it is evident that reason has here presupposed that the conception
of an ens realissimum is perfectly adequate to the conception of a
being of absolute necessity, that is, that we may infer the
existence of the latter from that of the former- a proposition which
formed the basis of the ontological argument, and which is now
employed in the support of the cosmological argument, contrary to
the wish and professions of its inventors. For the existence of an
absolutely necessary being is given in conceptions alone. But if I
say: "The conception of the ens realissimum is a conception of this
kind, and in fact the only conception which is adequate to our idea of
a necessary being," I am obliged to admit, that the latter may be
inferred from the former. Thus it is properly the ontological argument
which figures in the cosmological, and constitutes the whole
strength of the latter; while the spurious basis of experience has
been of no further use than to conduct us to the conception of
absolute necessity, being utterly insufficient to demonstrate the
presence of this attribute in any determinate existence or thing.
For when we propose to ourselves an aim of this character, we must
abandon the sphere of experience, and rise to that of pure
conceptions, which we examine with the purpose of discovering
whether any one contains the conditions of the possibility of an
absolutely necessary being. But if the possibility of such a being
is thus demonstrated, its existence is also proved; for we may then
assert that, of all possible beings there is one which possesses the
attribute of necessity- in other words, this being possesses an
absolutely necessary existence.
All illusions in an argument are more easily detected when they
are presented in the formal manner employed by the schools, which we
now proceed to do.
If the proposition: "Every absolutely necessary being is likewise an
ens realissimum," is correct (and it is this which constitutes the
nervus probandi of the cosmological argument), it must, like all
affirmative judgements, be capable of conversion- the conversio per
accidens, at least. It follows, then, that some entia realissima are
absolutely necessary beings. But no ens realissimum is in any
respect different from another, and what is valid of some is valid
of all. In this present case, therefore, I may employ simple
conversion, and say: "Every ens realissimum is a necessary being." But
as this proposition is determined a priori by the conceptions
contained in it, the mere conception of an ens realissimum must
possess the additional attribute of absolute necessity. But this is
exactly what was maintained in the ontological argument, and not
recognized by the cosmological, although it formed the real ground
of its disguised and illusory reasoning.
Thus the second mode employed by speculative reason of demonstrating
the existence of a Supreme Being, is not only, like the first,
illusory and inadequate, but possesses the additional blemish of an
ignoratio elenchi- professing to conduct us by a new road to the
desired goal, but bringing us back, after a short circuit, to the
old path which we had deserted at its call.
I mentioned above that this cosmological argument contains a perfect
nest of dialectical assumptions, which transcendental criticism does
not find it difficult to expose and to dissipate. I shall merely
enumerate these, leaving it to the reader, who must by this time be
well practised in such matters, to investigate the fallacies
residing therein.
The following fallacies, for example, are discoverable in this
mode of proof: 1. The transcendental principle: "Everything that is
contingent must have a cause"- a principle without significance,
except in the sensuous world. For the purely intellectual conception
of the contingent cannot produce any synthetical proposition, like
that of causality, which is itself without significance or
distinguishing characteristic except in the phenomenal world. But in
the present case it is employed to help us beyond the limits of its
sphere. 2. "From the impossibility of an infinite ascending series
of causes in the world of sense a first cause is inferred"; a
conclusion which the principles of the employment of reason do not
justify even in the sphere of experience, and still less when an
attempt is made to pass the limits of this sphere. 3. Reason allows
itself to be satisfied upon insufficient grounds, with regard to the
completion of this series. It removes all conditions (without which,
however, no conception of Necessity can take place); and, as after
this it is beyond our power to form any other conceptions, it
accepts this as a completion of the conception it wishes to form of
the series. 4. The logical possibility of a conception of the total of
reality (the criterion of this possibility being the absence of
contradiction) is confound. ed with the transcendental, which requires
a principle of the practicability of such a synthesis- a principle
which again refers us to the world of experience. And so on.
The aim of the cosmological argument is to avoid the necessity of
proving the existence of a necessary being priori from mere
conceptions- a proof which must be ontological, and of which we feel
ourselves quite incapable. With this purpose, we reason from an actual
existence- an experience in general, to an absolutely necessary
condition of that existence. It is in this case unnecessary to
demonstrate its possibility. For after having proved that it exists,
the question regarding its possibility is superfluous. Now, when we
wish to define more strictly the nature of this necessary being, we do
not look out for some being the conception of which would enable us to
comprehend the necessity of its being- for if we could do this, an
empirical presupposition would be unnecessary; no, we try to
discover merely the negative condition (conditio sine qua non),
without which a being would not be absolutely necessary. Now this
would be perfectly admissible in every sort of reasoning, from a
consequence to its principle; but in the present case it unfortunately
happens that the condition of absolute necessity can be discovered
in but a single being, the conception of which must consequently
contain all that is requisite for demonstrating the presence of
absolute necessity, and thus entitle me to infer this absolute
necessity a priori. That is, it must be possible to reason conversely,
and say: The thing, to which the conception of the highest reality
belongs, is absolutely necessary. But if I cannot reason thus- and I
cannot, unless I believe in the sufficiency of the ontological
argument- I find insurmountable obstacles in my new path, and am
really no farther than the point from which I set out. The
conception of a Supreme Being satisfies all questions a priori
regarding the internal determinations of a thing, and is for this
reason an ideal without equal or parallel, the general conception of
it indicating it as at the same time an ens individuum among all
possible things. But the conception does not satisfy the question
regarding its existence- which was the purpose of all our inquiries;
and, although the existence of a necessary being were admitted, we
should find it impossible to answer the question: What of all things
in the world must be regarded as such?
It is certainly allowable to admit the existence of an
all-sufficient being- a cause of all possible effects- for the purpose
of enabling reason to introduce unity into its mode and grounds of
explanation with regard to phenomena. But to assert that such a
being necessarily exists, is no longer the modest enunciation of an
admissible hypothesis, but the boldest declaration of an apodeictic
certainty; for the cognition of that which is absolutely necessary
must itself possess that character.
The aim of the transcendental ideal formed by the mind is either
to discover a conception which shall harmonize with the idea of
absolute necessity, or a conception which shall contain that idea.
If the one is possible, so is the other; for reason recognizes that
alone as absolutely necessary which is necessary from its
conception. But both attempts are equally beyond our power- we find it
impossible to satisfy the understanding upon this point, and as
impossible to induce it to remain at rest in relation to this
incapacity.
Unconditioned necessity, which, as the ultimate support and stay
of all existing things, is an indispensable requirement of the mind,
is an abyss on the verge of which human reason trembles in dismay.
Even the idea of eternity, terrible and sublime as it is, as
depicted by Haller, does not produce upon the mental vision such a
feeling of awe and terror; for, although it measures the duration of
things, it does not support them. We cannot bear, nor can we rid
ourselves of the thought that a being, which we regard as the greatest
of all possible existences, should say to himself: I am from
eternity to eternity; beside me there is nothing, except that which
exists by my will; whence then am I? Here all sinks away from under
us; and the greatest, as the smallest, perfection, hovers without stay
or footing in presence of the speculative reason, which finds it as
easy to part with the one as with the other.
Many physical powers, which evidence their existence by their
effects, are perfectly inscrutable in their nature; they elude all our
powers of observation. The transcendental object which forms the basis
of phenomena, and, in connection with it, the reason why our
sensibility possesses this rather than that particular kind of
conditions, are and must ever remain hidden from our mental vision;
the fact is there, the reason of the fact we cannot see. But an
ideal of pure reason cannot be termed mysterious or inscrutable,
because the only credential of its reality is the need of it felt by
reason, for the purpose of giving completeness to the world of
synthetical unity. An ideal is not even given as a cogitable object,
and therefore cannot be inscrutable; on the contrary, it must, as a
mere idea, be based on the constitution of reason itself, and on
this account must be capable of explanation and solution. For the very
essence of reason consists in its ability to give an account, of all
our conceptions, opinions, and assertions- upon objective, or, when
they happen to be illusory and fallacious, upon subjective grounds.
Detection and Explanation of the Dialectical Illusion in
all Transcendental Arguments for the Existence of a
Necessary Being.
Both of the above arguments are transcendental; in other words, they
do not proceed upon empirical principles. For, although the
cosmological argument professed to lay a basis of experience for its
edifice of reasoning, it did not ground its procedure upon the
peculiar constitution of experience, but upon pure principles of
reason- in relation to an existence given by empirical
consciousness; utterly abandoning its guidance, however, for the
purpose of supporting its assertions entirely upon pure conceptions.
Now what is the cause, in these transcendental arguments, of the
dialectical, but natural, illusion, which connects the conceptions
of necessity and supreme reality, and hypostatizes that which cannot
be anything but an idea? What is the cause of this unavoidable step on
the part of reason, of admitting that some one among all existing
things must be necessary, while it falls back from the assertion of
the existence of such a being as from an abyss? And how does reason
proceed to explain this anomaly to itself, and from the wavering
condition of a timid and reluctant approbation- always again
withdrawn- arrive at a calm and settled insight into its cause?
It is something very remarkable that, on the supposition that
something exists, I cannot avoid the inference that something exists
necessarily. Upon this perfectly natural- but not on that account
reliable- inference does the cosmological argument rest. But, let me
form any conception whatever of a thing, I find that I cannot cogitate
the existence of the thing as absolutely necessary, and that nothing
prevents me- be the thing or being what it may- from cogitating its
non-existence. I may thus be obliged to admit that all existing things
have a necessary basis, while I cannot cogitate any single or
individual thing as necessary. In other words, I can never complete
the regress through the conditions of existence, without admitting the
existence of a necessary being; but, on the other hand, I cannot
make a commencement from this being.
If I must cogitate something as existing necessarily as the basis of
existing things, and yet am not permitted to cogitate any individual
thing as in itself necessary, the inevitable inference is that
necessity and contingency are not properties of things themselves-
otherwise an internal contradiction would result; that consequently
neither of these principles are objective, but merely subjective
principles of reason- the one requiring us to seek for a necessary
ground for everything that exists, that is, to be satisfied with no
other explanation than that which is complete a priori, the other
forbidding us ever to hope for the attainment of this completeness,
that is, to regard no member of the empirical world as
unconditioned. In this mode of viewing them, both principles, in their
purely heuristic and regulative character, and as concerning merely
the formal interest of reason, are quite consistent with each other.
The one says: "You must philosophize upon nature," as if there existed
a necessary primal basis of all existing things, solely for the
purpose of introducing systematic unity into your knowledge, by
pursuing an idea of this character- a foundation which is
arbitrarily admitted to be ultimate; while the other warns you to
consider no individual determination, concerning the existence of
things, as such an ultimate foundation, that is, as absolutely
necessary, but to keep the way always open for further progress in the
deduction, and to treat every determination as determined by some
other. But if all that we perceive must be regarded as conditionally
necessary, it is impossible that anything which is empirically given
should be absolutely necessary.
It follows from this that you must accept the absolutely necessary
as out of and beyond the world, inasmuch as it is useful only as a
principle of the highest possible unity in experience, and you
cannot discover any such necessary existence in the would, the
second rule requiring you to regard all empirical causes of unity as
themselves deduced.
The philosophers of antiquity regarded all the forms of nature as
contingent; while matter was considered by them, in accordance with
the judgement of the common reason of mankind, as primal and
necessary. But if they had regarded matter, not relatively- as the
substratum of phenomena, but absolutely and in itself- as an
independent existence, this idea of absolute necessity would have
immediately disappeared. For there is nothing absolutely connecting
reason with such an existence; on the contrary, it can annihilate it
in thought, always and without self-contradiction. But in thought
alone lay the idea of absolute necessity. A regulative principle must,
therefore, have been at the foundation of this opinion. In fact,
extension and impenetrability- which together constitute our
conception of matter- form the supreme empirical principle of the
unity of phenomena, and this principle, in so far as it is empirically
unconditioned, possesses the property of a regulative principle.
But, as every determination of matter which constitutes what is real
in it- and consequently impenetrability- is an effect, which must have
a cause, and is for this reason always derived, the notion of matter
cannot harmonize with the idea of a necessary being, in its
character of the principle of all derived unity. For every one of
its real properties, being derived, must be only conditionally
necessary, and can therefore be annihilated in thought; and thus the
whole existence of matter can be so annihilated or suppressed. If this
were not the case, we should have found in the world of phenomena
the highest ground or condition of unity- which is impossible,
according to the second regulative principle. It follows that
matter, and, in general, all that forms part of the world of sense,
cannot be a necessary primal being, nor even a principle of
empirical unity, but that this being or principle must have its
place assigned without the world. And, in this way, we can proceed
in perfect confidence to deduce the phenomena of the world and their
existence from other phenomena, just as if there existed no
necessary being; and we can at the same time, strive without ceasing
towards the attainment of completeness for our deduction, just as if
such a being- the supreme condition of all existences- were
presupposed by the mind.
These remarks will have made it evident to the reader that the ideal
of the Supreme Being, far from being an enouncement of the existence
of a being in itself necessary, is nothing more than a regulative
principle of reason, requiring us to regard all connection existing
between phenomena as if it had its origin from an all-sufficient
necessary cause, and basing upon this the rule of a systematic and
necessary unity in the explanation of phenomena. We cannot, at the
same time, avoid regarding, by a transcendental subreptio, this formal
principle as constitutive, and hypostatizing this unity. Precisely
similar is the case with our notion of space. Space is the primal
condition of all forms, which are properly just so many different
limitations of it; and thus, although it is merely a principle of
sensibility, we cannot help regarding it as an absolutely necessary
and self-subsistent thing- as an object given a priori in itself. In
the same way, it is quite natural that, as the systematic unity of
nature cannot be established as a principle for the empirical
employment of reason, unless it is based upon the idea of an ens
realissimum, as the supreme cause, we should regard this idea as a
real object, and this object, in its character of supreme condition,
as absolutely necessary, and that in this way a regulative should be
transformed into a constitutive principle. This interchange becomes
evident when I regard this supreme being, which, relatively to the
world, was absolutely (unconditionally) necessary, as a thing per
se. In this case, I find it impossible to represent this necessity
in or by any conception, and it exists merely in my own mind, as the
formal condition of thought, but not as a material and hypostatic
condition of existence.
