Moral Letters to Lucilius Section 4

Magni animi est magna contemnere ac mediocria malle quam nimia. Illa enim utilia vitaliaque sunt; at haec eo, quod superfluunt, nocent. Sic segetem nimia sternit ubertas, sic rami nimio onere franguntur, sic ad maturitatem non pervenit nimia fecunditas. Idem animis quoque evenit, quos inmoderata felicitas rumpit, qua non tantum in aliorum iniuriam, sed etiam in suam utuntur.

Il est d’une âme grande de mépriser les grandeurs, et d’aimer mieux la médiocrité que l’excès : la médiocrité seule est utile et fait vivre l’homme ; l’excès nuit par son superflu même. Ainsi versent les épis trop pressés ; ainsi la branche surchargée de fruits se rompra ; ainsi l’exubérance n’arrive point à maturité. Il en est de même des esprits ; une prospérité sans mesure les brise :

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.
