‘Pluralism: is causation many different things?’ proposes that no single theory can explain all cases of causation. Socrates' belief that there is a single essence to something is compared with Wittgenstein's suggestion that some of our notions could be thought of as family resemblance concepts. But how many causes does pluralism require? Ned Hall believes just two concepts are necessary, whereas Aristotle spoke of there being four causes: the material cause, formal cause, efficient cause, and final cause. What is common to all causal truths is that we use them to make a certain kind of inference. The inferentialist view is then discussed.
