The words proud and pride , on the contrary, are sometimes taken in a good sense. We frequently say of a man, that he is too proud, or that he has too much noble pride, ever to suffer himself to do a mean thing. Pride is, in this case, confounded with magnanimity.
 Adam Smith, The Theory of Moral Sentiments (1759). copy citation

Context

“We sometimes say of a man, when we are talking of him in good-humour, that he is the better for his vanity, or that his vanity is more diverting than offensive; but we still consider it as a foible and a ridicule in his character.
The words proud and pride , on the contrary, are sometimes taken in a good sense. We frequently say of a man, that he is too proud, or that he has too much noble pride, ever to suffer himself to do a mean thing. Pride is, in this case, confounded with magnanimity. Aristotle, a philosopher who certainly knew the world, in drawing the character of the magnanimous man, paints him with many features which, in the two last centuries, were commonly ascribed to the Spanish character: that he was deliberate in all his resolutions; slow, and even tardy, in all his actions; that his voice was grave, his speech deliberate, his step and motion slow; that he appeared indolent and even slothful, not at all disposed to bustle about little matters, but to act with the most determined and vigorous resolution upon all great and illustrious occasions; that he was not a lover of danger, or forward to expose himself to little dangers, but to great dangers; and that, when he exposed himself to danger, he was altogether regardless of his life.17
