Context

“So great is the force of custom that out of those whom nature has only made men, are created all conditions of men. For some districts are full of masons, others of soldiers, etc. Certainly nature is not so uniform. It is custom then which does this, for it constrains nature. But sometimes nature gains the ascendancy, and preserves man's instinct, in spite of all custom, good or bad. 98 Bias leading to error.—It is a deplorable thing to see all men deliberating on means alone, and not on the end. Each thinks how he will acquit himself in his condition; but as for the choice of condition, or of country, chance gives them to us.” source
