... there is no such thing as a rational world and a separate irrational world, but only one world containing both.

The truth is not a crystal that can be slipped into one's pocket, but an endless current into which one falls headlong.

If there is a sense of reality, there must also be a sense of possibility.

We have gained reality and lost dream. No more lounging under a tree and peering at the sky between one's big and second toes; there's work to be done. To be efficient, one cannot be hungry and dreamy but must eat steak and keep moving.

It will always be the same possibilities, in sum or on the average, that go on repeating themselves until a man comes along who does not value the actuality above idea. It is he who first gives the new possibilities their meaning, their direction, and he awakens them.

And what would you do, ... if you could rule the world for a day? I suppose I would have no choice but to abolish reality.

A particularly fine head on a man usually means that he is stupid; particularly deep philosophers are usually shallow thinkers; in literature, talents not much above the average are usually regarded by their contemporaries as geniuses.
