To begin with, we put the proposition: pure phenomenology is the science of pure consciousness.

We would be in a nasty position indeed if empirical science were the only kind of science possible.

In all the areas within which the spiritual life of humanity is at work, the historical epoch wherein fate has placed us is an epoch of stupendous happenings.

The ideal of a pure phenomenology will be perfected only by answering this question; pure phenomenology is to be separated sharply from psychology at large and, specifically, from the descriptive psychology of the phenomena of consciousness.

All consciousness is consciousness of something

Merely fact-minded sciences make merely fact-minded people.

To every object there correspond an ideally closed system of truths that are true of it and, on the other hand, an ideal system of possible cognitive processes by virtue of which the object and the truths about it would be given to any cognitive subject.
