In brief:<\/strong> It is the part of the system that has aged most \u2014 but not for the reason usually given. Hegel did not want to invent<\/em> nature out of the concept. He said expressly that natural science precedes the philosophy of nature, and that nature precisely cannot<\/em> be comprehended without remainder. What really catches up with him is the developmental history of life \u2013 and even there not as an error about facts, but as a decision about what a genus is.<\/p>\n\n\n\n

The charge<\/h2>\n\n\n\n

It runs roughly thus: Hegel believed one could derive the laws of nature at one\u2019s desk from the concept<\/a>, held Newton for a bungler and Goethe\u2019s theory of colours for correct, and incidentally proved that there could be only seven planets. The last point is a legend and is taken apart elsewhere<\/a>. The first two deserve a more exact answer.<\/p>\n\n\n\n

What Hegel himself says about the relation to experience<\/h2>\n\n\n\n

Right at the beginning of the philosophy of nature stands a sentence that removes the ground from the charge:<\/p>\n\n\n\n

\n

Not only must philosophy be in agreement with the experience of nature, but the emergence and formation of the philosophical science has empirical physics for its presupposition and condition.<\/p>\nEncyclopaedia (1830), \u00a7 246 Remark<\/cite><\/blockquote>\n\n\n\n

The philosophy of nature therefore invents nothing; it takes the material that natural science supplies and asks after its order. Hegel distinguishes strictly between the emergence<\/em> of a science, in which experience is the basis, and the finished<\/em> science, in which the necessity of the concept establishes the order. Whoever overlooks this distinction reads each of his derivations as a claim about how nature was made.<\/p>\n\n\n\n

The \u201eimpotence of nature\u201c \u2014 Hegel\u2019s own limit<\/h2>\n\n\n\n

The decisive paragraph is \u00a7 250. It says that nature precisely does not sustain the concept:<\/p>\n\n\n\n

\n

It is the impotence of nature to preserve the determinations of the concept only abstractly, and to expose the working out of the particular to external determinability.<\/p>\nEncyclopaedia (1830), \u00a7 250<\/cite><\/blockquote>\n\n\n\n

From this he draws the consequence himself \u2014 and against the philosophy of nature of his contemporaries, not against its critics:<\/p>\n\n\n\n

\n

That impotence of nature sets limits to philosophy, and it is most improper to demand of the concept that it should comprehend such contingencies and, as it has been called, construct or deduce them.<\/p>\nEncyclopaedia (1830), \u00a7 250 Remark<\/cite><\/blockquote>\n\n\n\n

In a footnote he becomes impolite. A critic had demanded that the philosophy of nature kindly deduce his pen:<\/p>\n\n\n\n

\n

Herr Krug once, in this and at the same time in another respect quite naive sense, called upon the philosophy of nature to perform the feat of deducing merely his pen. \u2013 One might have given him hope of this achievement [\u2026] once science had advanced so far [\u2026] that there was nothing more important left to comprehend.<\/p>\nEncyclopaedia (1830), \u00a7 250 Remark, footnote<\/cite><\/blockquote>\n\n\n\n

The man who supposedly wanted to derive everything from the concept declared the deriving of the singular to be \u201emost improper\u201c.<\/p>\n\n\n\n

Where Hegel is wrong \u2013 and where he is not<\/h2>\n\n\n\n

Two things have to be kept apart here that are usually named in one breath.<\/p>\n\n\n\n

The reserve.<\/strong> \u00a7 249 says that the stages of nature proceed from one another \u2013<\/p>\n\n\n\n

but not in such a way that the one were naturally produced out of the other, but rather in the inner Idea that constitutes the ground of nature.<\/p>Encyclopaedia (1830), \u00a7 249<\/cite><\/blockquote>\n\n\n\n

That is the same rule that holds in the Groundlines<\/em>, \u00a7 32<\/a> note: the conceptual order is not the temporal one. The family logically presupposes the concept of property and was historically there first all the same. Whoever holds that rule to be right in the sphere of right cannot hold it against Hegel in the sphere of nature. It is consistent, not evasive.<\/p>\n\n\n\n

The addition.<\/strong> But he does not stop there. In the same paragraph he adds:<\/p>\n\n\n\n

It has been a clumsy representation of older, and also of more recent, philosophy of nature to regard the development and transition of one natural form and sphere into a higher one as an externally actual production, which, however, in order to make it clearer, has been relegated to the darkness of the past \u2026 Thinking consideration must rid itself of such nebulous, at bottom sensuous representations, such as in particular the so-called emergence of plants and animals out of water, and then the emergence of the more developed animal organisations out of the lower ones.<\/p>Encyclopaedia (1830), \u00a7 249 Remark<\/cite><\/blockquote>\n\n\n\n

That is no longer a methodological reserve but a claim about what happened \u2013 and it is false. His own procedure did not require this addition. He could have said: the temporal question is not mine. Instead he says: that is not how it was.<\/p>\n\n\n\n

What the polemic is aimed at<\/h2>\n\n\n\n

The addition is nevertheless intelligible. What Hegel had before him was no research programme but speculative philosophy of nature, which took the sequence of stages for an actual production and, as he says mockingly, \u201ein order to make it clearer, relegated it to the darkness of the past\u201c. Against Oken and his kin the contempt is earned.<\/p>\n\n\n\n

The evolutionary idea itself is older than both \u2013 Anaximander has human beings emerge from fish, Empedocles has limbs join together by chance, Lucretius transmits it \u2013 and Hegel knew it. But it shares with the nature-philosophising of his own day exactly the defect he censures: it asserts a succession and names no mechanism. Nobody had heredity and selection in 1830. Twenty-nine years after this edition Darwin\u2019s Origin of Species<\/em> appeared \u2013 and the succession was suddenly no longer an intimation but something explained. What Hegel rejected was an evolutionism without a mechanism, and that was fit to be rejected.<\/p>\n\n\n\n

The fork in the road: \u00a7 250 Remark<\/h2>\n\n\n\n

So far the matter would be a mere lag. It is more than that, and a passage seldom read in this connection shows it. Hegel knows very well what the findings yield:<\/p>\n\n\n\n

Nature everywhere blurs the essential limits by intermediate and defective formations, which always furnish instances against every fixed distinction \u2013 even within determinate genera (for example that of human beings) by monstrosities, which on the one hand must be counted to that genus, while on the other they lack determinations that would have to be regarded as the essential peculiarity of the genus. \u2013 In order to be able to regard such formations as defective, bad, misshapen, a fixed type is presupposed; but this type could not be drawn from experience, for it is experience that furnishes those so-called monstrosities, deformities, intermediate things and so forth.<\/p>Encyclopaedia (1830), \u00a7 250 Remark<\/cite><\/blockquote>\n\n\n\n

That is the same finding from which Darwin sets out: the blurred limits, the intermediate forms, the impossibility of obtaining the type from the material. The inferences run in opposite directions. Hegel: therefore<\/em> the type does not come from experience but from the concept. Darwin: therefore<\/em> there is no fixed type, the intermediate things are what is real, and the species is the abstraction.<\/p>\n\n\n\n

The same finding, two decisions. At this point the dispute is no empirical lag but a philosophical fork \u2013 and the question at issue is not whether species have changed, but what a genus<\/a> is.<\/p>\n\n\n\n

What the dispute really costs<\/h2>\n\n\n\n

Less than it looks, and in a different place more.<\/p>\n\n\n\n

Less<\/strong> at the level of the great stages. That nature falls apart at all into mechanics, physics and organics, into geological, vegetable and animal nature, is no claim about descent, and the theory of descent does not touch this order. And at the level of species Hegel has already vacated the field: the \u201eimpotence of nature\u201c leaves \u201ethe working out of the particular to external determinability\u201c. In the lecture he puts it in passing and more sharply: \u201eFrom the determination of matter I cannot develop what kinds of matter there are.\u201c From the concept of the animal one cannot develop which animals there are. That is exactly where evolution works \u2013 in the zone Hegel had already withdrawn from the concept himself. There it costs him nothing.<\/p>\n\n\n\n

More<\/strong> at the concept of the genus. For Hegel it is a standard on which the singular fails:<\/p>\n\n\n\n

Its inadequacy to universality is its original disease and the innate germ of death.<\/p>Encyclopaedia (1830), \u00a7 375<\/cite><\/blockquote>\n\n\n\n

The animal dies because it does not suffice for the genus. In Darwin the genus is conversely a result: what the surviving populations share. Ground against result. The two can be brought closer by saying that the theory of descent makes productive, over time, the inadequacy of the singular to the universal that already stands in Hegel. That is attractive, but it turns the genus from an ought into a statistic. At this point a present-day reader has to decide something and not merely reinterpret.<\/p>\n\n\n\n

What remains of Hegel\u2019s basic motive is independent of this: that a temporal succession is not yet an explanation but itself needs explaining. The theory of evolution has not refuted that motive but fulfilled it \u2013 it supplied the mechanism that Hegel found missing in his contemporaries.<\/p>\n\n\n\n

Why the Groundlines do not depend on it<\/h2>\n\n\n\n

The philosophy of right does not stand on the philosophy of nature but beside it. It begins expressly where nature leaves off:<\/p>\n\n\n\n

\n

The ground of right is the realm of spirit in general; its more precise location and point of departure is the will<\/em>, which is free<\/em>, so that freedom constitutes its substance and determination, and the system of right is the realm of actualized freedom, the world of spirit produced from within itself as a second nature<\/em>.<\/p>\nGroundlines, \u00a7 4<\/a><\/cite><\/blockquote>\n\n\n\n

What the Groundlines need from the philosophy of nature is exactly one sentence: that nature is not the ground of right. The arguments about property<\/a>, contract<\/a>, punishment<\/a> and the state<\/a> hang on no physical assumption whatever. One can strike out the philosophy of nature without a single sentence in the Groundlines falling over \u2014 and therefore the Achilles heel, if it is one, is at any rate not the heel on which the thinking about right depends.<\/p>\n\n\n\n
