Philosophy as science, as serious, rigorous, indeed apodictically rigorous science – the dream is over.

All consciousness is consciousness of something.

Immanent and transcendent experience are nevertheless connected in a remarkable way: by a change in attitude, we can pass from the one to the other.

So far as their own phenomenal content is concerned, they do not suffer in any way when believing in Objective actuality is put out of play.

All philosophical disciplines are rooted in pure phenomenology, through whose development, and through it alone, they obtain their proper force.

A new fundamental science, pure phenomenology, has developed within philosophy: This is a science of a thoroughly new type and endless scope.

Psychology, on the other hand, is science of psychic Nature and, therefore, of consciousness as Nature or as real event in the spatiotemporal world.

What phenomenology wants, in all these investigations, is to establish what admits of being stated with the universal validity of theory.

I must achieve internal consistency.

All perception is a gamble.
