The gods deal with good men according to the same rule as schoolmasters with their pupils, who exact most labour from those of whom they have the surest hopes. Do you imagine that the Lacedaemonians, who test the mettle of their children by public flogging, do not love them? Their own fathers call upon them to endure the strokes of the rod bravely, and when they are torn and half dead, ask them to offer their wounded skin to receive fresh wounds. Why then should we wonder if God tries noble spirits severely? There can be no easy proof of virtue. Fortune lashes and mangles us: well, let us endure it: it is not cruelty, it is a struggle, in which the oftener we engage the braver we shall become. The strongest part of the body is that which is exercised by the most frequent use: we must entrust ourselves to Fortune to be hardened by her against herself: by degrees she will make us a match for herself. Familiarity with danger leads us to despise it. Thus the bodies of sailors are hardened by endurance of the sea, and the hands of farmers by work; the arms of soldiers are powerful to hurl darts, the legs of runners are active: that part of each man which he exercises is the strongest: so by endurance the mind becomes able to despise the power of misfortunes.
