The Analogy

Abstract

The argument from analogy is presented in a favourable light in order to properly assess it. It is comprised of two premises. According to the parity premise, the arguments for a moral error theory would entail an epistemic error theory. According to the epistemic existence premise an epistemic error theory is false. It is argued that the parity premise can be given two readings. The first reading—internalism-parity—targets the internalism-based moral error theory. The second reading—irreducibility-parity—targets the irreducibility-based moral error theory. Both readings are motivated. It is claimed that they are plausible and that the argument from analogy represents a strong case against the moral error theory.
