Agency and Manipulability Causation: What’s the Difference in Practice?

Agency “ … an event A is a cause of a distinct event B just in case bringing about the occurrence of A would be an effective means by which a free agent could bring about the occurrence of B.‖ [Menzies and Prince, 1993: 187] Manipulability “...the change in B, if any, that is produced by the manipulation of A should be produced only via a causal route that goes through A.” [Woodward, 2008: §§5] The Koch-Henle Postulates (1) The organism must be shown to be constantly present in characteristic form and arrangement in the diseased tissue. (2) The organism which, from its behaviour appears to be responsible for the disease, must be isolated and grown in pure culture. (3) The pure culture must be shown to induce the disease experimentally.
