Astronomers tell us that planets, after they have finished their progressive motion, for some small time acquiesce and become stationary, as they term it. Now in the study of philosophy it is not so; there is no point of rest or acquiescence during the whole procedure, for the nature of progress is to be always advancing, more or less. The scales in which our actions are, as it were, weighed cannot at all stand in equilibrio, but our soul is continually either raised by the addition of good, or cast with the counterpoise of evil.

Therefore, as the oracle told the Cirrhaeans that they ought to fight continually, day and night; so you and every wise man ought to be perpetually upon your guard, and if you can be assured that you maintain a constant combat with vice, that you are always at enmity with it and never so much as come to terms, or receive any diversions, applications, or avocations, as so many heralds from the enemies’ camp, in order to a treaty with it; then you may, with a great deal of confidence and alacrity, go on with the management of your warlike expedition, and very reasonably at last expect a conquest, and enjoy a crown of righteousness for your reward.
