I was teaching philosophical ethics yesterday and came across these quotations I’d saved up about the possibility of human freedom.
The first, from Thomas Nagel, simply describes what a hard-core version of determinism looks like:
Some people have thought that it is never possible for us to do anything different from what we actually do, in the absolute sense. They acknowledge that what we do depends on our choices, decisions, and wants, and that we make different choices in different circumstances: we’re not like the earth rotating on its axis with monotonous regularity. But the claim is that, in each case, the circumstances that exist before we act determine our actions and make them inevitable. The sum total of a person’s experiences, desires and knowledge, his or her hereditary constitution, the social circumstances and the nature of the choice facing them, together with other factors that we may not know about, all combine to make a particular acting in the circumstances inevitable. This view is called determinism… [quoted in Alban McCoy, An Intelligent Person's Guide to Christian Ethics, 34-35]
The second quotation, from Isaiah Berlin, is about how freedom is in fact a presupposition of ordinary personal and social life, whether we like to admit it philosophically or not:
The whole of our common morality, in which we speak of obligation and duty, right and wrong, moral praise and blame – the way in which people are praised or condemned, rewarded or punished, for behaving in a way in which they were not forced to behave, when they could have behaved otherwise – this network of beliefs and practices, on which all current morality seems to me to depend, presupposes the notion of responsibility, and responsibility entails the ability to choose between black and white, right and wrong, pleasure and duty; as well as, in a wider sense, between forms of life, forms of government, and the whole constellations of moral values in terms of which most people, however much they may or may not be aware of it, do in fact live. [Liberty, 324]
