I must, however, be of opinion, that the sentiments of those, who are inclined to think favourably of mankind, are more advantageous to virtue, than the contrary principles, which give us a mean opinion of our nature. When a man is prepossessed with a high notion of his rank and character in the creation, he will naturally endeavour to act up to it, and will scorn to do a base or vicious action, which might sink him below that figure which he makes in his own imagination. Accordingly we find, that all our polite and fashionable moralists insist upon this topic, and endeavour to represent vice as unworthy of man, as well as odious in itself.
David Hume, Of the Dignity or Meanness of Human Nature.
