Humanity is the virtue of a woman, generosity of a man.7 The fair-sex, who have commonly much more tenderness than ours, have seldom so much generosity.

Context

“The propriety of generosity and public spirit is founded upon the same principle with that of justice. Generosity is different from humanity. Those two qualities, which at first sight seem so nearly allied, do not always belong to the same person. Humanity is the virtue of a woman, generosity of a man.7 The fair-sex, who have commonly much more tenderness than ours, have seldom so much generosity. That women rarely make considerable donations, is an observation of the civil law.j Humanity consists merely in the exquisite fellow-feeling which the spectator entertains with the sentiments of the persons principally concerned, so as to grieve for their sufferings, to resent their injuries, and to rejoice at their good fortune.” source
