...potted thinking is easily accepted, is concentrated in form, and has lost the vitamins essential to mental nourishment. - Susan Stebbing

Perceiving involves more than being sensibly aware of something present to the senses; it involves the activity of perceiving. This is the activity of a person, and in perceiving, the whole person is involved, not merely one or other of his sense organs.

We are content to accept without testing any belief that fits in with our prejudices and whose truth is necessary for the satisfaction of our desires.

We must face the unfortunate fact that we are moved to the acceptance of beliefs by factors that are wholly irrelevant to their truth.
