 to transform it into social property, necessarily follows. This advance however does not signify the restoration of the old primitive common property, but the establishment of a far higher better developed form of communal proprietorship, which, far from being an impediment to production, rather, for the first time is bound to put an end to its limitations and to give it the full benefit of modern discoveries in chemistry and mechanical inventions.

But the necessity of clearness on this point led to the doctrine of a soul which could leave the body, then to the idea of the immortality of the soul, finally, to monotheism. The old materialism was therefore negated by idealism. But in the further development of philosophy idealism became untenable, and is negated by modern materialism. This, the negation of negation, is not the mere reestablishment of the old, but unites, with the surviving foundations, the whole thought content of a two thousand years development of philosophy and science, as well as the history of these two thousand years. It is in a special sense no philosophy but a single concept of the universe which has to prove and realise itself not in a science of sciences apart, but in actual science. Philosophy is here also cast aside, that is "destroyed and preserved," destroyed as to its form, preserved as to its real content. Where Herr Duehring only sees word-jugglery a more real content is brought to light by the newer point of view.

Finally, even the Rousseau doctrine of equality, of which that of Herr Duehring is only a feeble and false plagiarism, has no existence unless the Hegelian
