Harman (1986) asserts that logic is neither a normative nor a psychological theory and, although immediate implication and inconsistency may play a role in reasoning, there is nothing special about logic in this connection. Field (2009) purports to reject these claims but actually accepts them and concludes that, because of the semantic paradoxes, logic is ‘somehow connected to norms of thought’. A real non sequitur!
