Letter 81 (§1)

“You complain that you have met with an ungrateful person. If this is your first experience of that sort, you should offer thanks either to your good luck or to your caution. In this case, however, caution can effect nothing but to make you ungenerous. For if you wish to avoid such a danger, you will not confer benefits; and so, that benefits may not be lost with another man, they will be lost to yourself. It is better, however, to get no return than to confer no benefits. Even after a poor crop one should sow again; for often losses due to continued barrenness of an unproductive soil have been made good by one year's fertility.”
