History of Western Philosophy - Bertrand Russell [409]
The above arguments assume, as Kant does, that percepts are caused by 'things in themselves', or, as we should say, by events in the world of physics. This assumption, however, is by no means logically necessary. If it is abandoned, percepts cease to be in any important sense 'subjective', since there is nothing with which to contrast them.
The 'thing-in-itself' was an awkward element in Kant's philosophy, and was abandoned by his immediate successors, who accordingly fell into something very like solipsism. Kant's inconsistencies were such as to make it inevitable that philosophers who were influenced by him should develop rapidly either in the empirical or in the absolutist direction; it was, in fact, in the latter direction that German philosophy moved until after the death of Hegel.
Kant's immediate successor, Fichte (1762–1814), abandoned 'things in themselves', and carried subjectivism to a point which seems almost to involve a kind of insanity. He holds that the Ego is the only ultimate reality, and that it exists because it posits itself; the non-Ego, which has a subordinate reality, also exists only because the Ego posits it. Fichte is not important as a pure philosopher, but as the theoretical founder of German nationalism, by his Addresses to the German Nation (1807–8), which were intended to rouse the Germans to resistance to Napoleon after the battle of Jena. The Ego as a metaphysical concept easily became confused with the empirical Fichte; since the Ego was German, it followed that the Germans were superior to all other nations. 'To have character and to be a German,' says Fichte, 'undoubtedly mean the same thing.' On this basis he worked out a whole philosophy of nationalistic totalitarianism, which had great influence in Germany.
His immediate successor Schelling (1775–1854) was more amiable but not less subjective. He was closely associated with the German romantics; philosophically, though famous in his day, he is not important. The important development from Kant's philosophy was that of Hegel.

CURRENTS OF THOUGHT IN THE NINETEENTH CENTURY
The intellectual life of the nineteenth century was more complex than that of any previous age. This was due to several causes. First: the area concerned was larger than ever before; America and Russia made important contributions, and Europe became more aware than formerly of Indian philosophies, both ancient and modern. Second: science, which had been a chief source of novelty since the seventeenth century, made new conquests, especially in geology, biology, and organic chemistry. Third: machine production profoundly altered the social structure, and gave men a new conception of their powers in relation to the physical environment. Fourth: a profound revolt, both philosophical and political, against traditional systems in thought, in politics, and in economics, gave rise to attacks upon many beliefs and institutions that had hitherto been regarded as unassailable. This revolt had two very different forms, one romantic, the other rationalistic. (I am using these words in a liberal sense.) The romantic revolt passes
