page 227 CHAPTER FOUR THE PHILOSOPHICAL IDEALISTS AS COMRADES-IN-ARMS AND SUCCESSORS OF EMPIRIO-CRITICISM So far we have examined empirio- philosophical trends. First comes the criticism taken by itself. We must now question of the relation of Mach and examine it in its historical development and Avenarius to Kant. in its connection and relation with other 1.

As a matter of fact, the opinion, had not sufficiently "purified development of German classical experience." It is with this "purification of philosophy immediately after Kant gave rise to a criticism of Kantianism exactly It is evident from this that the Humean along the very line followed by Avenarius. Schulze rejects Kant's doctrine of the This line is represented in German thing-in-itself as an inconsistent classical philosophy by Schulze- concession to materialism, i.e., to the Aenesidemus, an adherent of Humean "dogmatic" assertion that in our sensations agnosticism, and by J.

We Kant on the grounds that the latter's sceptics, or followers of Hume, says assumption of the thing-in-itself contradicts Schulze, reject the thing-in-itself as being agnosticism and leads to materialism. In "beyond the bounds of all experience" (p. the same way, but even more vigorously, 57). We reject objective knowledge (p. 25); Kant is criticised by the subjective idealist we deny that space and time really exist Fichte, who maintains that Kant's outside us (p. 100); we reject the presence assumption of the thing-in-itself in our experience of necessity (p. 112), independent of the self is "realism " causality, force, etc. (p. 113).

Fichte sees a crying "dogmatically," saying that since we cannot inconsistency in the assumption of Kant think otherwise there is therefore an a and the Kantians that the thing-in-itself is priori law of thought.

Kant in no way agnosticism of Kant (agnosticism is a refuted the idealist Berkeley (pp. 268-72). denial of objective reality given in sensation), but for a purer agnosticism, for the elimination of Kant's assumption, which itself to be unknowable, transcendental, is contradictory to agnosticism, that there is other-sided, he is an idealist. Recognising a thing-in itself, albeit unknowable, experience, sensations, as the only source noumenal and other-sided, that there is of our knowledge, Kant is directing his necessity and causality, albeit a priori, philosophy towards sensationalism, and given in our understanding, and not in via sensationalism, under certain objective reality. He fought Kant not from conditions, towards materialism. the Left, as the materialists fought Kant, Recognising the apriority of space, time, but from the Right, as the sceptics and causality, etc., Kant is directing his idealists fought Kant. He imagined that he philosophy towards idealism. Both was advancing, when in reality he was consistent materialists and consistent retreating to the programme of criticising idealists (as well as the "pure" agnostics, Kant which Kuno Fischer, speaking of the Humeans) have mercilessly criticised Schulze-Aenesidemus, aptly characterised Kant for this inconsistency. The in the following words: "The critique of pure materialists blamed Kant for his idealism, reason with pure reason [i.e., apriorism] left rejected the idealist features of his system, out is scepticism.

The whole campaign of the Russian Machians agnostics and idealists blamed Kant for his against Engels and Marx. The latest assumption of the thing-in-itself as a discovery by Bogdanov and Bazarov, concession to materialism, "realism" or Yushkevich and Valentinov, trumpeted by "naive realism." Thc agnostics, moreover, them in a thousand different keys, is that rejected not only the thing-in-itself, but Plekhanov is making a "luckless attempt to apriorism as well; while the idealists reconcile Engels with Kant by the aid of a demanded the consistent deduction from compromise -- a thing-in-itself which is just pure thought not only of the a priori forms a wee bit knowable" (Studies,[85] etc., p. of the under standing, but of the world as a 67 and many other places). This discovery whole (by magnifying human thought to an of our Machians discloses a veritable abstract Self or to an "Absolute Idea," or to bottomless pit of utter confusion and a "Universal Will," etc., etc.). And here our monstrous misunderstanding both of Kant Machians, "without noticing" that they had and of the whole course of development of taken as their teachers men who had German classical philosophy.
