I am truly horrified by modern man. Such absence of feeling, such narrowness of outlook, such lack of passion and information, such feebleness of thought.

Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men.

Human development is a form of chronological unfairness, since late-comers are able to profit by the labors of their predecessors without paying the same price.

Unaware of the absurdity of it, we introduce our own petty household rules into the economy of the universe for which the life of generations, peoples, of entire planets, has no importance in relation to the general development.

One must open men's eyes, not tear them out.

I believe in nothing here, except a handful of people, a few ideas, and the fact that one cannot arrest movement.

We could hardly believe that after so many ordeals, after all the trials of modern skepticism, there was still so much left in our souls to destroy.
