Isaiah Berlin: Doing

“Single-minded monists, ruthless fanatics, men possessed by an all-embracing coherent vision do not know the doubts and agonies of those who cannot wholly blind themselves to reality.”

Isaiah Berlin

Five Essays on Liberty (2002), Introduction (1969)
Context: Those, no doubt, are in some way fortunate who have brought themselves, or have been brought by others, to obey some ultimate principle before the bar of which all problems can be brought. Single-minded monists, ruthless fanatics, men possessed by an all-embracing coherent vision do not know the doubts and agonies of those who cannot wholly blind themselves to reality.

“If I am prevented by others from doing what I could otherwise do, I am to that degree unfree; and if this area is contracted by other men beyond a certain minimum, I can be described as being coerced, or, it may be, enslaved.”

Isaiah Berlin

Five Essays on Liberty (2002), Two Concepts of Liberty (1958)
Context: I am normally said to be free to the degree to which no man or body of men interferes with my activity. Political liberty in this sense is simply the area within which a man can act unobstructed by others. If I am prevented by others from doing what I could otherwise do, I am to that degree unfree; and if this area is contracted by other men beyond a certain minimum, I can be described as being coerced, or, it may be, enslaved. Coercion is not, however, a term that covers every form of inability. If I say that I am unable to jump more than ten feet in the air, or cannot read because I am blind, or cannot understand the darker pages of Hegel, it would be eccentric to say that I am to that degree enslaved or coerced. Coercion implies the deliberate interference of other human beings within the area in which I could otherwise act.

Men

“This they do in the service of an imaginary science; and, like the astrologers and soothsayers whom they have succeeded, cast up their eyes to the clouds, and speak in immense, unsubstantiated images and similes, in deeply misleading metaphors and allegories, and make use of hypnotic formulae with little regard for experience, or rational argument, or tests of proven reliability. Thereby they throw dust in their own eyes as well as in ours, obstruct our vision of the real world, and further confuse an already sufficiently bewildered public about the relations of morality to politics, and about the nature and methods of the natural sciences and historical studies alike.”

“What has been shown by Machiavelli, who is often (like Nietzsche) congratulated for tearing off hypocritical masks, brutally revealing the truth, and so on, is not that men profess one thing and do another (although no doubt he shows this too) 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 (as the existentialists call it, or of “false consciousness,” to use a Marxist formula) 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.”

“Injustice, poverty, slavery, ignorance — these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible.”
