Self-interest makes some people blind, and others sharp-sighted.

Some people displease with merit, and others' very faults and defects are pleasing.

People's personalities, like buildings, have various facades, some pleasant to view, some not.

Heat of blood makes young people change their inclinations often, and habit makes old ones keep to theirs a great while.

The name and pretense of virtue is as serviceable to self-interest as are real vices.

The sure way to be cheated is to think one's self more cunning than others.
