Epicurus says, "gratitude is a virtue that has commonly profit annexed to it." And where is the virtue that has not? But still the virtue is to be valued for itself, and not for the profit that attends it.
Seneca the YoungerVirtue is shut out from no one; she is open to all, accepts all, invites all, gentlemen, freedmen, slaves, kings, and exiles; she selects neither house nor fortune; she is satisfied with a human being without adjuncts.
Seneca the Younger
