"What has been shown by Machiavelli, who is often congratulated for tearing off hypocritical masks, brutally revealing the truth, and so on, is not that men profess one thing and do another but that when they assume that the two ideals are compatible, or perhaps are even one and the same ideal, and do not allow this assumption to be questioned, they are guilty of bad faith which their actual behavior exhibits. Machiavelli calls the bluff not just of official morality—the hypocrisies of ordinary life—but of one of the foundations of the central Western philosophical tradition, the belief in the ultimate compatibility of all genuine values. His own withers are unwrung. He has made his choice. He seems wholly unworried by, indeed scarcely aware of, parting company with traditional Western morality."

“Isaiah Berlin, Beyond the Wit" by Evan R. Goldstein”

“If, as I believe, the ends of men are many, and not all of them are in principle compatible with each other, then the possibility of conflict — and of tragedy — can never wholly be eliminated from human life, either personal or social. The necessity of choosing between absolute claims is then an inescapable characteristic of the human condition. This gives its value to freedom as Acton conceived of it — as an end in itself, and not as a temporary need, arising out of our confused notions and irrational and disordered lives, a predicament which a panacea could one day put right.”

“For there exists a great chasm between those, on one side, who relate everything to a single central vision, one system, less or more coherent or articulate, in terms of which they understand, think and feel - a single, universal, organising principle in terms of which alone all that they are and say has significance - and, on the other side, those who pursue many ends, often unrelated and even contradictory, connected, if at all, only in de facto way for some psychological or physiological cause, related to no moral or aesthetic principle. This last lead lives, perform acts and entertain ideas that are centrifugal rather than centripetal; their thought is scattered or difused, moving on many levels, seizing upon the essence of a vast variety of experiences and objects; for they are themselves, consciously or unconsciously seeking to fit them into or exclude them from any one unchanging, all-embracing, sometimes self-contradictory and incomplete at times fanatical, military inner vision. The first kind of intellectual and artistic personality belongs to the hedgehogs, the second to the foxes.”

“All forms of tampering with human beings, getting at them, shaping them against their will to your own pattern, all thought control and conditioning is, therefore, a denial of that in men which makes them men and their values ultimate.”

“Few new truths have ever won their way against the resistance of established ideas save by being overstated.”
