This is exactly the picture laid by the standard textbook gloss. All phenomenology can do is describe feeble, fleeting, and personal events in consciousness. It seems impossible to say such a theory would lay solid foundations for philosophy as rigorous science. Here we make a claim. If phenomenology is to hold ground as a legitimate science phenomena must not be viewed as finding its origin in consciousness.
Phenomena appear in consciousness.
They are separate from consciousness. Husserl clarifies further just what an phenomenological investigation entails. We already know it will not be seeking objectively valid data. By knowledge of the consciousness in which they appear. It strives for essential knowledge of consciousness.
