“What,” argues he, “if you do not know whether your man be ungrateful or grateful⁠—will you wait until you know, or will you not lose the opportunity of bestowing a benefit? To wait is a long business⁠—for, as Plato says, it is hard to form an opinion about the human mind⁠—not to wait, is rash.” To this objector we shall answer, that we never should wait for absolute knowledge of the whole case, since the discovery of truth is an arduous task, but should proceed in the direction in which truth appeared to direct us. All our actions proceed in this direction: it is thus that we sow seed, that we sail upon the sea, that we serve in the army, marry, and bring up children. The result of all these actions is uncertain, so we take that course from which we believe that good results may be hoped for. Who can guarantee a harvest to the sower, a harbour to the sailor, victory to the soldier, a modest wife to the husband, dutiful children to the father? We proceed in the way in which reason, not absolute truth, directs us. Wait, do nothing that will not turn out well, form no opinion until you have searched but the truth, and your life will pass in absolute inaction. Since it is only the appearance of truth, not truth itself, which leads me hither or thither, I shall confer benefits upon the man who apparently will be grateful.
