By freedom he meant a condition in which men were not prevented from choosing both the object and the manner of their worship. For him only a society in which this condition was realised could be called fully human. Its realisation was an ideal which Mill regarded as more precious than life itself.

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.

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.

The very desire for guarantees that our values are eternal and secure in some objective heaven is perhaps only a craving for the certainties of childhood or the absolute values of our primitive past.

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.

But to manipulate men, to propel them towards goals which you - the social reformer - see, but they may not, is to deny their human essence, to treat them as objects without wills of their own, and therefore to degrade them.

Everything is what it is: liberty is liberty, not equality or fairness or justice or culture, or human happiness or a quiet conscience.

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.

The notion that one can discover large patterns or regularities in the procession of historical events is naturally attractive to those who are impressed by the success of the natural sciences in classifying, correlating, and above all predicting.

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.
