Letter 39 — On Noble Aspirations (§4)

“It is the quality of a great soul to scorn great things and to prefer that which is ordinary rather than that which is too great. For the one condition is useful and life-giving; but the other does harm just because it is excessive. Similarly, too rich a soil makes the grain fall flat, branches break down under too heavy a load, excessive productiveness does not bring fruit to ripeness. This is the case with the soul also; for it is ruined by uncontrolled prosperity, which is used not only to the detriment of others, but also to the detriment of itself.”
