Example text

The logical empiricists early identified several features of a law on which there has continued to be wide agreement: laws are universal statements of the form “All a’s are b’s” or “if event e happens, then invariably, event f occurs”. For example, “All pure samples of iron conduct electric currents at standard temperature and pressure” or “if an electric current is applied to a sample of iron under standard temperature and pressure, then the sample conducts the current”. These are terminological variants of the same law.

The first condition guarantees the relevance of the explanans to the explanandum. The second condition is so stated to exclude as an explanation a patently non-explanatory argument like: 1 2 All free-falling bodies have constant acceleration. It rained on Monday. Therefore, 3 It rained on Monday. Notice this argument satisfies all the other conditions on explanation. In particular, it is a deductively valid argument because every proposition deductively implies itself, so 2 implies 3. But it is no explanation, if only because nothing can explain itself!

If we substitute for “Belgium” something more general, such as “any nation’s”, the result is more general, but plainly false. One response to the fact that many explanations don’t cite laws that are often made in defense of D-N explanation is to argue that such explanations are “explanation sketches” which could eventually be filled out to satisfy D-N strictures, especially once we have uncovered all the boundary conditions and the relevant laws of human action. Counterexamples of this sort in the natural sciences are more difficult to find, and defenders of the D-N model are confident they can deal with such cases by arguing that the alleged counterexample does satisfy all conditions.
