Perfection is immutable. But for things imperfect change is the way to perfect them. It gets the name of wilfulness when it will not admit of a lawful change to the better. Therefore constancy without knowledge cannot be always good. In things ill it is not virtue, but an absolute vice.
Owen FelthamTruth and fidelity are the pillars of the temple of the world; when these are broken, the fabric falls, and crushes all to pieces.
Owen FelthamIrresolution is a worse vice than rashness. He that shoots best may sometimes miss the mark; but he that shoots not at all can never hit it. Irresolution loosens all the joints of a state; like an ague, it shakes not this nor that limb, but all the body is at once in a fit. The irresolute man is lifted from one place to another; so hatcheth nothing, but addles all his actions.
