“The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: “his bow-wow manner must have had a good deal to do with the effect produced.””
—Virginia Woolf (1882–1941)
“Continual success in obtaining those things which a man from time to time desireth, that is to say, continual prospering, is that men call FELICITY; I mean Felicity of this life. For there is no such thing as perpetual Tranquillity of mind, while we live here; because Life it self is but Motion, and can never be without Desire, nor without Faeroe, no more than without Sense.”
—Thomas Hobbes (1579–1688)
“Give the slave the least elevation of religious sentiment, and he is not slave: you are the slave: he not only in his humility feels his superiority, feels that much deplored condition of his to be a fading trifle, but he makes you feel it too. He is the master.”
—Ralph Waldo Emerson (1803–1882)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“False greatness is unsociable and remote: conscious of its own frailty, it hides, or at least averts its face, and reveals itself only enough to create an illusion and not be recognized as the meanness that it really is. True greatness is free, kind, familiar and popular; it lets itself be touched and handled, it loses nothing by being seen at close quarters; the better one knows it, the more one admires it.”
—Jean De La Bruyère (1645–1696)
