Am I a good person? Deep down, do I even really want to be a good person, or do I only want to seem like a good person so that people (including myself) will approve of me? Is there a difference? How do I ever actually know whether I'm bullshitting myself, morally speaking?
One can study what exists and how consciousness functions; but one cannot analyze (or “prove”) existence as such, or consciousness as such. These are irreducible primaries. (An attempt to “prove” them is self-contradict ory: it is an attempt to “prove” existence by means of nonexistence, and consciousness by means of unconsciousness. )
