"Virtues are dispositions not only to act in particular ways, but also to feel in particular ways. To act virtuously is not, as Kant was later to think, to act against inclination; it is to act from inclination formed by the cultivation of the virtues."

The whole of education should be designed so as to occupy a boy's free time in cultivation of his body.  He has no right to loaf about idly; but after his day's work is done, he ought to harden his young body, so that life may not find him soft when he enters it.  No one should be allowed to sin at the expense of posterity, that is, of the race.
