The harp, and the viol, the tabret, and pipe, and wine, are in their feasts: but they regard not the work of the LORD, neither consider the operation… - Isaiah Berlin

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.

Knowledge increases autonomy both in the sense of Kant, and in that of Spinoza and his followers. I should like to ask once more: is all liberty just that? The advance of knowledge stops men from wasting their resources upon delusive projects. It has stopped us from burning witches or flogging lunatics or predicting the future by listening to oracles or looking at the entrails of animals or the flight of birds. It may yet render many institutions and decisions of the present – legal, political, moral, social – obsolete, by showing them to be as cruel and stupid and incompatible with the pursuit of justice or reason or happiness or truth as we now think the burning of widows or eating the flesh of an enemy to acquire skills. If our powers of prediction, and so our knowledge of the future, become much greater, then, even if they are never complete, this may radically alter our view of what constitutes a person, an act, a choice; and eo ipso our language and our picture of the world. This may make our conduct more rational, perhaps more tolerant, charitable, civilised, it may improve it in many ways, but will it increase the area of free choice? For individuals or groups?

And it shall come to pass in the last days, that the mountain of the LORD's house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
