Letters 66.33

As reason is, so also are actions; therefore all actions are equal. For since they resemble reason, they also resemble each other. Moreover, I hold that actions are equal to each other in so far as they are honourable and right actions. There will be, of course, great differences according as the material varies, as it becomes now broader and now narrower, now glorious and now base, now manifold in scope and now limited. However, that which is best in all these cases is equal; they are all honourable.
