The bird is gone, and in what meadow does it now sing?

What constitutes the authentic human being?

We are in a maze which we built, and then we fell into, now can't get out. To make the game into something real, something more than merely an intellectual exercise, we elected to lose our exceptional faculties, to reduce us an entire level. This unfortunately, includes a loss of memory.

I think that, like in my writing, reality is always a soap bubble, Silly Putty thing anyway. In the universe people are in, people put their hands through the walls, and it turns out they're living in another century entirely. I often have the feeling — and it does show up in my books — that this is all just a stage.

A man is an angel that has gone deranged.

The pre-Socratic Greek philosopher Parmenides taught that the only things that are real are things which never change... and the pre-Socratic Greek philosopher Heraclitus taught that everything changes. If you superimpose their two views, you get this result: Nothing is real.

I never liked the idea of doing what a machine says. I hate having to salute something built in a factory.
