Toward a new theory of causation
Abstract
In this paper today, I would like to offer a new analysis of causation and of causal claims. It is an unorthodox one, as you will see, but I suspect that in the not too distant future it will be seen as intuitively, perhaps even trivially, true. I hardly need defend the urgency of my project. Ever since Hume, philosophers have wondered whether there are causes. This is a desperate situation. With no causes, it's hard to see how brushing my teeth is likely to prevent tooth decay. Indeed, it would not be unreasonable to read Hume as an advocate of rotten teeth, which might explain the sad state that many British mouths find themselves in today. The attentive listener will have noted that I said Hume's advocacy of rotten teeth might explain the abysmal state of British oral hygiene. Of course, if Hume is right about causation then nothing explains anything, and that explains why I have been tentative in my claim. The account I would like to propose is this. The claim ‘x causes y’ is to be understood in the following way: ‘x makes y happen’. That is, to say that x is the cause of y is just to say that x makes y happen. Or, to put it more succinctly, if x is the cause of y, then x makes y happen. This is no doubt a startling claim, and one in need of further clarification and defense. To begin, I should like to contrast my analysis with another that might, on its surface, appear similar. Suppose one were to claim that 'x is the cause of y' means that x brings y about. But ‘bringing about’ is hardly an informative verbal clause, and does little ampliative work. This way of putting it lacks the opaque transparency that we’ve come to expect of philosophical analyses of causation. Now this new account is not necessarily inconsistent with other, more traditional analyses, such as Lewis and Hausman's analyses of causation in terms of counterfactuals or Eells' probabilistic theory of causation. Consider first counterfactual analyses of causation. These are efforts to account for the meaning of causal dependencies..
