The Time of Our Lives

Published online by Cambridge University Press:  04 May 2010

Extract

Early last century an article appeared which transformed the philosophy of time. The article was James Ellis McTaggart's ‘The unreality of time’, published in 1908. As his title implies, McTaggart argued in this article that there is in reality no such thing as time. But that claim, although startling enough, is not what makes the article so remarkable. The same claim had after all been made long before McTaggart, for example by Kant in 1781, and in McTaggart's sense it is still made by those who think that time is merely one of the four dimensions of an unchanging ‘block universe’. However, most of those who think this are more influenced by Minkowski's comment, also made in 1908, that relativity has doomed space and time to ‘fade away into mere shadows’ of a unified spacetime than they are by McTaggart's more substantial arguments.

10 For present purposes we can neglect all such distances and delays. For first, they may be negligible, as they are for so-called ‘basic actions’ like moving our limbs (see Danto, Arthur, ‘Basic Actions’, American Philosophical Quarterly 2 (1965), 141148Google Scholar). And second, even when they are not negligible, they mostly only affect when an action ends, not when it starts. Thus my action, going to London, started almost as soon as I acquired the belief that it was time to leave Cambridge. That belief is what caused my action, i.e. caused it to start, then and there, even though the action ended sixty miles away and ninety minutes later. So even in this case it is true enough to say that our actions are caused by the beliefs and desires we have when we do them, meaning when we start to do them.
