Langton’s framework is a controversial interpretation of Kant. It argues that we can only know thin gs though being causally affected\, but the causal properties are irreducib le to the intrinsic properties\, and therefore the intrinsic properties are unknowable. Lewis’s framework is an exploration of the Ramsey-Carnap-Lewis account of theoretical terms. It argues that the fundamental theoretical t erms in the perfect science are multiply realizable\, and therefore their r ealizers are unknowable. Despite their difference in background\, they both use arguments whose premises involve the possibility of role changing – th e possibility that the same intrinsic/fundamental property can realize diff erent causal roles in other possible worlds. I present a new model of laws of nature which is different from the classical ones\, i.e. the strong law model and the reductionist model. It might show that Langton’s argument mig ht be unsound\, and Lewis’s argument might be weakened. I will then suggest a new way to modify Lewis’s argument to retain its argumentative power in the face of the model.\nView your event at http://www.google.com/calendar/e vent?action=VIEW&eid=YmdiNHRxZzJxMTh2NDltMmpwY2RpczdyODQgc3lkcGhpbEBhcnRzLn VzeWQuZWR1LmF1&tok=NTIjMmJlcm9za3ZqcjJnMjRyam50cWxxZWdzNm9AZ3JvdXAuY2FsZW5k YXIuZ29vZ2xlLmNvbTEzZjMyMzIyODQxMDcyNzQ1MTRiZWQ3NDgzYWYxYTliMjhmOTIwY2E&ctz =Australia/Sydney&hl=en_GB.
