There are four powers: memory and intellect, desire and covetousness. The two first are mental and the others sensual. The three senses sight, hearing, and smell cannot well be prevented; touch and taste not at all.

Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.

Whoever in discussion adduces authority uses not intellect but rather memory.

Those who, in debate, appeal to their qualifications, argue from memory, not from understanding.

A person must have a good memory to keep the promises he has made. A person must have a strong imagination to be able to have pity. So closely is morality tied to the quality of the intellect.

Memory says, 'I did that.' Pride replies, 'I could not have done that.' Eventually, memory yields.
