Famous quotes containing the words dark and/or matter:
“In business be as able as you can, but do not be cunning; cunning is the dark sanctuary of incapacity.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Hardly ever can a youth transferred to the society of his betters unlearn the nasality and other vices of speech bred in him by the associations of his growing years. Hardly ever, indeed, no matter how much money there be in his pocket, can he ever learn to dress like a gentleman-born. The merchants offer their wares as eagerly to him as to the veriest “swell,” but he simply cannot buy the right things.”
—William James (1842–1910)
