Kant's Critique of Judgement · Immanuel Kant
METHODOLOGY OF THE TELEOLOGICAL JUDGEMENT.[119]
The question is now, whether the objective reality of the concept of a final purpose of creation cannot be exhibited adequately to the theoretical requirements of pure Reason--if not apodictically for the determinant Judgement yet adequately for the maxims of the theoretical reflective Judgement? This is the least one could expect from theoretical philosophy, which undertakes to combine the moral purpose with natural purposes by means of the Idea of one single purpose; but yet this little is far more than it can accomplish. According to the principle of the theoretical reflective Judgement we should say: if we have ground for assuming for the purposive products of nature a supreme Cause of nature--whose causality in respect of the actuality of creation is of a different kind from that required for the mechanism of nature, _i.e._ must be thought as the causality of an Understanding--we have also sufficient ground for thinking in this original Being not merely the purposes everywhere in nature but also a final purpose. This is not indeed a final purpose by which we can explain the presence of such a Being, but one of which we may at least convince ourselves (as was the case in physical Teleology) that we can make the possibility of such a world conceivable, not merely according to purposes, but only through the fact that we ascribe to its existence a final purpose.
But a final purpose is merely a concept of our practical Reason, and can be inferred from no data of experience for the theoretical judging of nature, nor can it be applied to the cognition of nature. No use of this concept is possible except its use for practical Reason according to moral laws; and the final purpose of creation is that constitution of the world which harmonises with that which alone we can put forward definitely according to laws, viz. the final purpose of our pure practical Reason, in so far as it is to be practical.-- Now we have in the moral law, which enjoins on us in a practical point of view the application of our powers to the accomplishment of this final purpose, a ground for assuming its possibility and practicability, and consequently too (because without the concurrence of nature with a condition not in our power, its accomplishment would be impossible) a nature of things harmonious with it. Hence we have a moral ground for thinking in a world also a final purpose of creation.
We have not yet advanced from moral Teleology to a Theology, _i.e._ to the being of a moral Author of the world, but only to a final purpose of creation which is determined in this way. But in order to account for this creation, _i.e._ the existence of things, in accordance with a _final purpose_, we must assume not only first an intelligent Being (for the possibility of things of nature which we are compelled to judge of as _purposes_), but also a _moral_ Being, as author of the world, _i.e._ a _God_. This second conclusion is of such a character that we see it holds merely for the Judgement according to concepts of practical Reason, and as such for the reflective and not the determinant Judgement. It is true that in us morally practical Reason is essentially different in its principles from technically practical Reason. But we cannot assume that it must be so likewise in the supreme World-Cause, regarded as Intelligence, and that a peculiar mode of its causality is requisite for the final purpose, different from that which is requisite merely for purposes of nature. We cannot therefore assume that in our final purpose we have not merely a _moral ground_ for admitting a final purpose of creation (as an effect), but also for admitting a _moral Being_ as the original ground of creation. But we may well say, that, _according to the constitution of our rational faculty_, we cannot comprehend the possibility of such a purposiveness _in respect of the moral law_, and its Object, as there is in this final purpose, apart from an Author and Governor of the world, who is at the same time its moral Lawgiver.
The actuality of a highest morally-legislating Author is therefore sufficiently established merely _for the practical use_ of our Reason, without determining anything theoretically as regards its being. For Reason requires, in respect of the possibility of its purpose, which is given to us independently by its own legislation, an Idea through which the inability to follow up this purpose, according to the mere natural concepts of the world, is removed (sufficiently for the reflective Judgement). Thus this Idea gains practical reality, although all means of creating such for it in a theoretical point of view, for the explanation of nature and determination of the supreme Cause, are entirely wanting for speculative cognition. For the theoretical reflective Judgement physical Teleology sufficiently proves from the purposes of nature an intelligent World-Cause; for the practical Judgement moral Teleology establishes it by the concept of a final purpose, which it is forced to ascribe to creation in a practical point of view. The objective reality of the Idea of God, as moral Author of the world, cannot, it is true, be established by physical purposes _alone_. But nevertheless, if the cognition of these purposes is combined with that of the moral purpose, they are, by virtue of the maxim of pure Reason which bids us seek unity of principles so far as is possible, of great importance for the practical reality of that Idea, by bringing in the reality which it has for the Judgement in a theoretical point of view.
To prevent a misunderstanding which may easily arise, it is in the highest degree needful to remark that, in the first place, we can _think_ these properties of the highest Being only according to analogy. How indeed could we explore the nature of that, to which experience can show us nothing similar? Secondly, in this way we only think the supreme Being; we cannot thereby _cognise_ Him and ascribe anything theoretically to Him. It would be needful for the determinant Judgement in the speculative aspect of our Reason, to consider what the supreme World-Cause is in Himself. But here we are only concerned with the question what concept we can form of Him, according to the constitution of our cognitive faculties; and whether we have to assume His existence in order merely to furnish practical reality to a purpose, which pure Reason without any such presupposition enjoins upon us _a priori_ to bring about with all our powers, _i.e._ in order to be able to think as possible a designed effect.
Although that concept may be transcendent for the speculative Reason, and the properties which we ascribe to the Being thereby thought may, objectively used, conceal an anthropomorphism in themselves; yet the design of its use is not to determine the nature of that Being which is unattainable by us, but to determine ourselves and our will accordingly. We may call a cause after the concept which we have of its effect (though only in reference to this relation), without thereby meaning to determine internally its inner constitution, by means of the properties which can be made known to us solely by similar causes and must be given in experience. For example, amongst other properties we ascribe to the soul a _vis locomotiva_ because bodily movements actually arise whose cause lies in the representation of them; without therefore meaning to ascribe to it the only mode [of action] that we know in moving forces (viz. by attraction, pressure, impulse, and consequently motion, which always presuppose an extended being).
Just so we must assume _something_, which contains the ground of the possibility and practical reality, _i.e._ the practicability, of a necessary moral final purpose; but we can think of this, in accordance with the character of the effect expected of it, as a wise Being governing the world according to moral laws, and, conformably to the constitution of our cognitive faculties, as a cause of things distinct from nature, only in order to express the _relation_ of this Being (which transcends all our cognitive faculties) to the Objects of _our_ practical Reason. We do not pretend thus to ascribe to it theoretically the only causality of this kind known to us, viz. an Understanding and a Will: we do not even pretend to distinguish objectively the causality thought in this Being, as regards what is _for us_ final purpose, from the causality thought in it as regards nature (and its purposive determinations in general). We can only assume this distinction as subjectively necessary by the constitution of our cognitive faculties, and as valid for the reflective, not for the objectively determinant Judgement. But if we come to practice, then such a _regulative_ principle (of prudence or wisdom) [commanding us] to act conformably to that as purpose, which by the constitution of our cognitive faculties can only be thought as possible in a certain way, is at the same _constitutive_, _i.e._ practically determinant. Nevertheless, as a principle for judging of the objective possibility of things, it is no way theoretically determinant (_i.e._ it does not say that the only kind of possibility which belongs to the Object is that which belongs to our thinking faculty), but is a mere _regulative_ principle for the reflective Judgement.
_Remark_ This moral proof is not one newly discovered, although perhaps its basis is newly set forth; since it has lain in man’s rational faculty from its earliest germ, and is only continually developed with its advancing cultivation. So soon as men begin to reflect upon right and wrong--at a time when, quite indifferent as to the purposiveness of nature, they avail themselves of it without thinking anything more of it than that it is the accustomed course of nature--this judgement is inevitable, viz. that the issue cannot be the same, whether a man has behaved candidly or falsely, fairly or violently, even though up to his life’s end, as far as can be seen, he has met with no happiness for his virtues, no punishment for his vices. It is as if they perceived a voice within [saying] that the issue must be different. And so there must lie hidden in them a representation, however obscure, of something after which they feel themselves bound to strive; with which such a result would not agree,--with which, if they looked upon the course of the world as the only order of things, they could not harmonise that inner purposive determination of their minds.
Now they might represent in various rude fashions the way in which such an irregularity could be adjusted (an irregularity which must be far more revolting to the human mind than the blind chance that we are sometimes willing to use as a principle for judging of nature). But they could never think any other principle of the possibility of the unification of nature with its inner ethical laws, than a supreme Cause governing the world according to moral laws; because a final purpose in them proposed as duty, and a nature without any final purpose beyond them in which that purpose might be actualised, would involve a contradiction. As to the [inner][136] constitution of that World-Cause they could contrive much nonsense. But that moral relation in the government of the world would remain always the same, which by the uncultivated Reason, considered as practical, is universally comprehensible, but with which the speculative Reason can make far from the like advance.--And in all probability attention would be directed first by this moral interest to the beauty and the purposes in nature, which would serve excellently to strengthen this Idea though they could not be the foundation of it. Still less could that moral interest be dispensed with, because it is only in reference to the final purpose that the investigation of the purposes of nature acquires that immediate interest which displays itself in such a great degree in the admiration of them without any reference to the advantage to be derived from them.
As regards the hope of a future life, if instead of the final purpose we have to accomplish in conformity with the precept of the moral law, we ask of our theoretical faculty of cognition a clue for the judgement of Reason upon our destination (which clue is only considered as necessary or worthy of acceptance in a practical reference), then in this aspect Psychology, like Theology, gives no more than a negative concept of our thinking being. That is, none of its actions or of the phenomena of the internal sense can be explained materialistically; and hence of its separate nature and of the continuance or non-continuance of its personality after death absolutely no ampliative determinant judgement is possible on speculative grounds by means of our whole theoretical cognitive faculty. Here then everything is handed over to the teleological judging of our existence in a practically necessary aspect, and to the assumption of our continuance as a condition requisite for the final purpose absolutely furnished by Reason. And so this advantage (which indeed at first glance seems to be a loss) is apparent; that, as Theology for us can never be Theosophy, or rational _Psychology_ become _Pneumatology_--an ampliative science--so on the other hand this latter is assured of never falling into _Materialism_. Psychology, rather, is a mere anthropology of the internal sense, _i.e._ is the knowledge of our thinking self _in life_; and, as theoretical cognition, remains merely empirical. On the other hand, rational Psychology, as far as it is concerned with questions as to our eternal existence, is not a theoretical science at all, but rests on a single conclusion of moral Teleology; as also its whole use is necessary merely on account of the latter, _i.e._ on account of our practical destination.
For, in truth, when we meet with so many products in nature which are to us marks of an intelligent cause, why should we not think One cause rather than many; and in this One, not merely great intelligence, power, etc., but rather Omniscience, and Omnipotence--in a word, think it as a Cause that contains the sufficient ground of such properties in all possible things? Further, why should we not ascribe to this unique, all-powerful, original Being not only intelligence for natural laws and products, but also, as to a moral Cause of the world, supreme, ethical, practical Reason? For by this completion of the concept a sufficient principle is furnished both for insight into nature and for moral wisdom; and no objection grounded in any way can be made against the possibility of such an Idea.
If now at the same time the moral motives of the mind are aroused, and a lively interest in the latter is added by the force of eloquence (of which they are indeed very worthy), then there arises therefrom a persuasion of the objective adequacy of the proof; and also (in most cases of its use) a wholesome illusion which quite dispenses with all examination of its logical strictness, and even on the contrary regards this with abhorrence and dislike as if an impious doubt lay at its basis.--Now against this there is indeed nothing to say, so long as we only have regard to its popular usefulness. But then the division of the proof into the two dissimilar parts involved in the argument--belonging to physical and moral Teleology respectively--cannot and must not be prevented. For the blending of these makes it impossible to discern where the proper force of the proof lies, and in what part and how it must be elaborated in order that its validity may be able to stand the strictest examination (even if we should be compelled to admit in one part the weakness of our rational insight). Thus it is the duty of the philosopher (supposing even that he counts as nothing the claims of sincerity) to expose the above illusion, however wholesome it is, which such a confusion can produce; and to distinguish what merely belongs to persuasion from that which leads to conviction (for these are determinations of assent which differ not merely in degree but in kind), in order to present plainly the state of the mind in this proof in its whole clearness, and to be able to subject it frankly to the closest examination.
But a proof which is intended to convince, can again be of two kinds; either deciding what the object is _in itself_, or what it is _for us_ (for men in general) according to our necessary rational principles of judgement (proof κατ’ ἀλήθειαν or κατ’ ἄνθρωπον, the last word being taken in its universal signification of man in general). In the first case it is based on adequate principles for the determinant Judgement, in the second for the reflective Judgement. In the latter case it can never, when resting on merely theoretical principles, tend to conviction; but if a practical principle of Reason (which is therefore universally and necessarily valid) lies at its basis, it may certainly lay claim to conviction adequate in a pure practical point of view, _i.e._ to moral conviction. But a proof _tends to conviction_, though without convincing, if it is [merely][139] brought on the way thereto; _i.e._ if it contains in itself only objective grounds, which although not attaining to certainty are yet of such a kind that they do not serve merely for persuasion as subjective grounds of the judgement.[140]
All theoretical grounds of proof resolve themselves either into: (1) Proofs by logically strict _Syllogisms of Reason_; or where this is not the case, (2) _Conclusions_ according to _analogy_; or where this also has no place, (3) _Probable opinion_; or finally, which has the least weight, (4) Assumption of a merely possible ground of explanation, _i.e._ _Hypothesis_.--Now I say that all grounds of proof in general, which aim at theoretical conviction, can bring about no belief of this kind from the highest to the lowest degree, if there is to be proved the proposition of the _existence_ of an original Being, as a God, in the signification adequate to the whole content of this concept; viz. a _moral_ Author of the world, by whom the final purpose of creation is at the same time supplied. (1.) As to the _logically accurate_ proof proceeding from universal to particular, we have sufficiently established in the Critique the following: Since no intuition possible for us corresponds to the concept of a Being that is to be sought beyond nature--whose concept therefore, so far as it is to be theoretically determined by synthetical predicates, remains always problematical for us--there is absolutely no cognition of it to be had (by which the extent of our theoretical knowledge is in the least enlarged). The particular concept of a supersensible Being cannot be subsumed under the universal principles of the nature of things, in order to conclude from them to it, because those principles are valid simply for nature, as an object of sense.
(2.) We can indeed _think_ one of two dissimilar things, even in the very point of their dissimilarity, in accordance with the _analogy_[141] of the other; but we cannot, from that wherein they are dissimilar, _conclude_ from the one to the other by analogy, _i.e._ transfer from the one to the other this sign of specific distinction. Thus I can, according to the analogy of the law of the equality of action and reaction in the mutual attraction and repulsion of bodies, also conceive of the association of the members of a commonwealth according to rules of right; but I cannot transfer to it those specific determinations (material attraction or repulsion), and ascribe them to the citizens in order to constitute a system called a state.--Just so we can indeed conceive of the causality of the original Being in respect of the things of the world, as natural purposes, according to the analogy of an Understanding, as ground of the forms of certain products which we call works of art (for this only takes place on behalf of the theoretical or practical use that we have to make by our cognitive faculty of this concept in respect of the natural things in the world according to a certain principle). But we can in no way conclude according to analogy, because in the case of beings of the world Understanding must be ascribed to the cause of an effect which is judged artificial, that in respect of nature the same causality which we perceive in men attaches also to the Being which is quite distinct from nature. For this concerns the very point of dissimilarity which is thought between a cause sensibly conditioned in respect of its effects and the supersensible original Being itself in our concept of it, and which therefore cannot be transferred from one to the other.-- In the very fact that I must conceive the divine causality only according to the analogy of an Understanding (which faculty we know in no other being than in sensibly-conditioned man) lies the prohibition to ascribe to it this Understanding in its peculiar signification.[142]
(3.) _Opinion_ finds in _a priori_ judgements no place whatever, for by them we either cognise something as quite certain or else cognise nothing at all. But if the given grounds of proof from which we start (as here from the purposes in the world) are empirical, then we cannot even with their aid form any opinion as to anything beyond the world of sense, nor can we concede to such venturesome judgements the smallest claim to probability. For probability is part of a certainty possible in a certain series of grounds (its grounds compare with the sufficient ground as parts with a whole), the insufficient ground of which must be susceptible of completion. But since, as determining grounds of one and the same judgement, they must be of the same kind, for otherwise they would not together constitute a whole (such as certainty is), one part of them cannot lie within the bounds of possible experience and another outside all possible experience. Consequently, since merely empirical grounds of proof lead to nothing supersensible, and since what is lacking in the series of them cannot in any way be completed, we do not approach in the least nearer in our attempt to attain by their means to the supersensible and to a cognition thereof. Thus in any judgement about the latter by means of arguments derived from experience, probability has no place.
(4.) If an _hypothesis_ is to serve for the explanation of the possibility of a given phenomenon, at least its possibility must be completely certain.[143] It is sufficient that in an hypothesis I disclaim any cognition of actuality (which is claimed in an opinion given out as probable); more than this I cannot give up. The possibility of that which I place at the basis of my explanation, must at least be exposed to no doubt; otherwise there would be no end of empty chimeras. But to assume the possibility of a supersensible Being determined according to certain concepts would be a completely groundless supposition. For here none of the conditions requisite for cognition, as regards that in it which rests upon intuition, is given, and so the sole criterion of possibility remaining is the mere principle of Contradiction (which can only prove the possibility of the thought, not of the object thought). The result then is this. For the existence [Dasein] of the original Being, as a Godhead, or of the soul as an immortal spirit, absolutely no proof in a theoretical point of view is possible for the human Reason, which can bring about even the least degree of belief. The ground of this is quite easy to comprehend. For determining our Ideas of the supersensible we have no material whatever, and we must derive this latter from things in the world of sense, which is absolutely inadequate for such an Object. Thus, in the absence of all determination of it, nothing remains but the concept of a non-sensible something which contains the ultimate ground of the world of sense, but which does not furnish any knowledge (any amplification of the concept) of its inner constitution.
