Thomas Aquinas

“ Art. 1 - Whether meanness is a vice? Objection 1: It seems that meanness is not a vice. For just as vice moderates great things, so does it moderate little things: wherefore both the liberal and the magnificent do little things. But magnificence is a virtue. Therefore likewise meanness is a virtue rather than a vice. ”

“ Hence it is manifest that the vice of meanness, whereby a man intends to spend less than his work is worth, and thus fails to observe due proportion between his expenditure and his work, has a vice opposed to it, whereby a man exceeds this same proportion, by spending more than is proportionate to his work. ”

“ Just as the magnificent man has this in common with the liberal man, that he spends his money readily and with pleasure, so too the mean man in common with the illiberal or covetous man is loth and slow to spend. ”
