My experience is what I agree to attend to.

Whenever two people meet, there are really six people present. There is each man as he sees himself, each man as the other person sees him, and each man as he really is.

The total possible consciousness may be split into parts which co-exist but mutually ignore each other.

Compared with men, it is probable that brutes neither attend to abstract characters, nor have associations by similarity. Their thoughts probably pass from one concrete object to its habitual concrete successor far more uniformly than is the case with us. In other words, their associations of ideas are almost exclusively by contiguity. So far, however, as any brute might think by abstract characters instead of by association of con cretes, he would have to be admitted to be a reasoner in the true human sense. How far this may take place is quite uncertain.

The greatest empiricists among us are only empiricists on reflection: when left to their instincts, they dogmatize like infallible popes.

When you have broken the reality into concepts you never can reconstruct it in its wholeness.
