Three great men have entirely rejected teleology, or the explanation from final causes, and many small men have echoed them. These three are, Lucretius, Bacon of Verulam, and Spinoza. But in the case of all three we know clearly enough the source of this aversion, namely, that they regarded it as inseparable from speculative theology, of which, however, they entertained so great a distrust (which Bacon indeed prudently sought to conceal) that they wanted to give it a wide berth. We find Leibnitz also entirely involved in this prejudice, for, with characteristic naïveté, he expresses it as something self-evident in his Lettre à M. Nicaise (Spinozæ op. ed Paulus, vol. ii. p. 672): “Les causes finales, ou ce qui est la même chose, la consideration de la sagesse divine dans l'ordre des choses.” (The devil also même chose!) At the same point of view we find, indeed, Englishmen even at the present day. The Bridgewater-Treatise-men – Lord Brougham, &c. – nay, even Richard Owen also, in his “Ostéologie Comparée,” thinks precisely as Leibnitz, which I have already found fault with in the first volume. To all these teleology is at once also theology, and at every instance of design recognised in nature, instead of thinking and learning to understand nature, they break at once into the childish cry, “Design! design!” then strike up the refrain of their old wives' philosophy, and stop their ears against all rational arguments, such as, however, the great Hume has already advanced against them.5
The ignorance of the Kantian philosophy now, after seventy years, which is really a disgrace to Englishmen of learning, is principally responsible for this whole outcast position of the English; and this ignorance, again, depends, at least in great measure, upon the nefarious influence of the detestable English clergy, with whom stultification of every kind is a thing after their own hearts, so that only they may be able still to hold the English nation, otherwise so intelligent, involved in the most degrading bigotry; therefore, inspired by the basest obscurantism, they oppose with all their might the education of the people, the investigation of nature, nay, the advancement of all human knowledge in general; and both by means of their connections and by means of their scandalous, unwarrantable wealth, which increases the misery of the people, they extend their influence even to university teachers and authors, who accordingly (for example, Th. Brown, “On Cause and Effect”) resort to suppressions and perversions of every kind simply in order to avoid opposing even in a distant manner that “cold superstition” (as Pückler very happily designates their religion, or the current arguments in its favour).
But, on the other hand, the three great men of whom we are speaking, since they lived long before the dawn of the Kantian philosophy, are to be pardoned for their distrust of teleology on account of its origin; yet even Voltaire regarded the physico-theological proof as irrefutable. In order, however, to go into this somewhat more fully: first of all, the polemic of Lucretius (iv. 824-858) against teleology is so crude and clumsy that it refutes itself and convinces us of the opposite. But as regards Bacon (De augm. scient., iii. 4), he makes, in the first place, no distinction with reference to the use of final causes between organised and unorganised nature (which is yet just the principal matter), for, in his examples of final causes, he mixes the two up together. Then he banishes final causes from physics to metaphysics; but the latter is for him, as it is still for many at the present day, identical with speculative theology. From this, then, he regards final causes as inseparable, and goes so far in this respect that he blames Aristotle because he has made great use of final causes, yet without connecting them with speculative theology (which I shall have occasion immediately especially to praise). Finally, Spinoza (Eth. i. prop. 36, appendix) makes it abundantly clear that he identifies teleology so entirely with physico-theology, against which he expresses himself with bitterness, that he explains Natura nihil frustra agere: hoc est, quod in usum hominum non sit: similarly, Omnia naturalia tanquam ad suum utile media considerant, et credunt aliquem alium esse, qui illa media paraverit; and also: Hinc statuerunt, Deos omnia in usum hominum fecisse et dirigere. Upon this, then, he bases his assertion: Naturam finem nullum sibi præfixum habere et omnes causas finales nihil, nisi humana esse figmenta. His aim merely was to block the path of theism; and he had quite rightly recognised the physico-theological proof as its strongest weapon. But it was reserved for Kant really to refute this proof, and for me to give the correct exposition of its material, whereby I have satisfied the maxim: Est enim verum index sui et falsi. But Spinoza did not know how else to help himself but by the desperate stroke of denying teleology itself, thus design in the works of nature – an assertion the monstrosity of which is at once evident to every one who has gained any accurate knowledge of organised nature. This limited point of view of Spinoza, together with his complete ignorance of nature, sufficiently prove his entire incompetence in this matter, and the folly of those who, upon his authority, believe they must judge contemptuously of final causes.
Aristotle, who just here shows his brilliant side, contrasts very advantageously with these modern philosophers. He goes unprejudiced to nature, knows of no physico-theology – such a thing has never entered his mind, – and he has never looked at the world for the purpose of seeing whether it was a bungled piece of work. He is in his heart pure from all this, for he also sets up hypotheses as to the origin of animals and men (De generat. anim., iii. 11) without lighting upon the physico-theological train of thought. He always says: “ἡ φυσις ποιει (natura facit), never ἡ φυσις πεποιηται” (natura facta est). But after he has truly and diligently studied nature, he finds that it everywhere proceeds teleologically, and he says: “ματην ὁρωμεν ουδεν ποιουσαν την φυσιν” (naturam nihil frustra facere cernimus), De respir., c. 10; and in the books, De partibus animalium, which are a comparative anatomy: “Ουδε περιεργον ουδεν, ουτε ματην ἡ φυσις ποιει. – Ἡ φυσις ἑνεκα του ποιει παντα. – Πανταχου δε λεγομεν τοδε τουδε ἑνεκα, ὁπου αν φαινηται τελος τι, προς ὁ ἡ κινησις περαινει; ὡστε ειναι φανερον, ὁτι εστι τι τοιουτον, ὁ δη και καλουμεν φυσιν. Επει το σωμα οργανον; ἑνεκα τινος γαρ ἑκαστον των μοριων, ομοιως τε και το ὁλον.” (Nihil supervacaneum, nihil frustra natura facit. – Natura rei alicujus gratia facit omnia. – Rem autem hanc esse illius gratia asserere ubique solemus, quoties finem intelligimus aliquem, in quem motus terminetur; quocirca ejusmodi aliquid esse constat, quod Naturam vocamus. Est enim corpus instrumentum: nam membrum unumquodque rei alicujus gratia est, tum vero totum ipsum.) At greater length, p. 633 and 645 of the Berlin quarto edition, and also De incessu animalium, c. 2: “Ἡ φυσις ουδεν ποιει ματην, αλλ᾽ αει, εκ των ενδεχομενων τῃ ουσιᾳ, περι ἑκαστον γενος ζωου το αριστον.” (Natura nihil frustra facit, sed semper ex iis, quæ cuique animalium generis essentiæ contingunt, id quod optimum est.) But he expressly recommends teleology at the end of the books De generatione animalium, and blames Democritus for having denied it, which is just what Bacon, in his prejudice, praises in him. Especially, however, in the “Physica,” ii. 8, p. 198, Aristotle speaks ex professo of final causes, and establishes them as the true principle of the investigation of nature. In fact, every good and regular mind must, in considering organised nature, hit upon teleology, but unless it is determined by the preconceived opinions, by no means either upon physico-theology or upon the anthropo-teleology condemned by Spinoza. With regard to Aristotle generally, I wish further to draw attention to the fact here, that his teaching, so far as it concerns unorganised nature, is very defective and unserviceable, as in the fundamental conceptions of mechanics and physics he accepts the most gross errors, which is the less pardonable, since before him the Pythagoreans and Empedocles had been upon the right path and had taught much better. Empedocles indeed, as we learn from Aristotle's second book, De cœlo (c. 1, p. 284), had already grasped the conception of a tangential force arising from rotation, and counteracting
Let me here remark in passing that, judging from the German literature since Kant, one would necessarily believe that Hume's whole wisdom had consisted in his obviously false scepticism with regard to the law of causality, for this alone is everywhere referred to. In order to know Hume one must read his “Natural History of Religion” and his “Dialogues on Natural Religion.” There one sees him in his greatness, and these, together with Essay 21 “Of National Characters,” are the writings on account of which – I know of nothing that says more for his fame – even to the present day, he is everywhere hated by the English clergy.
