“Only when he has attained a final knowledge of all things will man have come to know himself. For things are only the boundaries of man.”

“Language as putative science. - The significance of language for the evolution of culture lies in this, that mankind set up in language a separate world beside the other world, a place it took to be so firmly set that, standing upon it, it could lift the rest of the world off its hinges and make itself master of it. To the extent that man has for long ages believed in the concepts and names of things as in aeternae veritates he has appropriated to himself that pride by which he raised himself above the animal: he really thought that in language he possessed knowledge of the world. The sculptor of language was not so modest as to believe that he was only giving things designations, he conceived rather that with words he was expressing supreame knowledge of things; language is, in fact, the first stage of occupation with science. Here, too, it is the belief that the truth has been found out of which the mightiest sources of energy have flowed. A great deal later - only now - it dawns on men that in their belief in language they have propagated a tremendous error. Happily, it is too late for the evolution of reason, which depends on this belief, to be put back. - Logic too depends on presuppositions with which nothing in the real world corresponds, for example on the presupposition that there are identical things, that the same thing is identical at different points of time: but this science came into existence through the opposite belief (that such conditions do obtain in the real world). It is the same with mathematics, which would certainly not have come into existence if one had known from the beginning that there was in nature no exactly straight line, no real circle, no absolute magnitude.”

“He who has attained the freedom of reason to any extent cannot, for a long time, regard himself otherwise than as a wanderer on the face of the earth - and not even as a traveler towards a final goal, for there is no such thing. But he certainly wants to observe and keep his eyes open to whatever actually happens in the world; therefore he cannot attach his heart too firmly to anything individual; he must have in himself something wandering that takes pleasure in change and transitoriness.”

“One thing a man must have: either a naturally light disposition or a disposition lightened by art and knowledge.”

“I do not believe that an “impulseto knowledge” is the father of philosophy; but that another impulse, here as elsewhere, has only made use of knowledge (and mistaken knowledge!) as an instrument.But whoever considers the fundamental impulses of man with a view to determining how far they may have here acted as INSPIRING GENII (or as demons and cobolds), will find that they have all practiced philosophy at one time or another, and that each one of them would have been only too glad to look upon itself as the ultimate end of existence and the legitimate LORD over all the other impulses.”

“No one can draw more out of things, books included, than he already knows. A man has no ears for that to which experience has given him no access.”

“The man of knowledge must be able not only to love his enemies but also to hate his friends.”
