Consciousness is a much smaller part of our mental life than we are conscious of, because we cannot be conscious of what we are not conscious of.

Consciousness is not wholly, nor even primarily a device for receiving sense-impressions.

There is no such thing as a complete consciousness.

I have no knowledge of myself as I am but only as I appear to myself. The consciousness of oneself is therefore very far from being a knowledge of oneself.

Whatever is beyond this narrow rational consciousness we mistake for our only consciousness.

We don't know much about our current selves, do we?

Consciousness is unquantifiable, a ghost in the machine, barely considered real at all, though in a sense this flickering mosaic of awareness is the only true reality that we can ever know.

Consciousness is not sharply defined, but fades into sub-consciousness; and beyond that we must postulate something indefinite but yet continuous with our mental nature. This I take it be the world-stuff.

Self-consciousness is not knowledge but a story one tells about oneself.

It is impossible to imagine existence in the absence of subjective sensation we call reflective consciousness.

I am very conscious that there is no scientific explanation for the fact that we are conscious.

There is no scientific explanation for consciousness yet it is.

What you call the subconscious, is in my opinion the real human consciousness.

If most of us remain ignorant of ourselves, it is because self-knowledge is painful and we prefer the pleasures of illusion.
