To be forward to praise others implies either great eminence, that can afford to, part with applause; or great quickness of discernment, with confidence in our own judgments; or great sincerity and love of truth, getting the better of our self-love.
William HazlittWe had rather do anything than acknowledge the merit of another if we can help it. We cannot bear a superior or an equal. Hence ridicule is sure to prevail over truth, for the malice of mankind, thrown into the scale, gives the casting weight.
William HazlittBelieve all the good you can of everyone. Do not measure others by yourself. If they have advantages which you have not, let your liberality keep pace with their good fortune. Envy no one, and you need envy no one.
William Hazlitt
