continual variety of actions all the whole course of his life, that he
has slipped away clear and undecided from the most daring critics. I can
more hardly believe a man's constancy than any other virtue, and believe
nothing sooner than the contrary. He that would judge of a man in detail
and distinctly, bit by bit, would oftener be able to speak the truth. It
is a hard matter, from all antiquity, to pick out a dozen men who have
formed their lives to one certain and constant course, which is the
principal design of wisdom; for to comprise it all in one word, says one
of the ancients, and to contract all the rules of human life into one,
"it is to will, and not to will, always one and the same thing: I will
not vouchsafe," says he, "to add, provided the will be just, for if it be
not just, it is impossible it should be always one." I have indeed
formerly learned that vice is nothing but irregularity, and want of
measure, and therefore 'tis impossible to fix constancy to it. 'Tis a
saying of. Demosthenes, "that the beginning oh all virtue is
consultation and deliberation; the end and perfection, constancy." If we
would resolve on any certain course by reason, we should pitch upon the
best, but nobody has thought on't:

"Quod petiit, spernit; repetit, quod nuper omisit;
AEstuat, et vitae disconvenit ordine toto."

["That which he sought he despises; what he lately lost, he seeks

life."--Horace, Ep., i. I, 98.]

Our ordinary practice is to follow the inclinations of our appetite, be

by the breath of occasion. We never meditate what we would have till the
instant we have a mind to have it; and change like that little creature
