 Because Hume’s analysis takes “the glue” out of the causal relation—a cause doesn’t make its effect occur, it is only regularly followed by its effect—it is commonly classified as skeptical. And in a sense it is, if one treats the making-things-happen “glue” to be essential to any relation properly called “causal”. But Hume’s views are not radical enough to count as skeptical in the sense intended by legal theoreticians. For Hume gives what Saul Kripke calls a “skeptical solution” to the problem of causation (1982: 66–68): Hume doesn’t deny that causation exists, but he reduces it to something less ontologically queer than “glue”.
