Read part 1: Tom Sorell on why human beings are the only animals who act morally.
Read part 2: Mark Rowlands argues that animals can act morally – we need to look at the evidence.
Read part 4: Anthropomorphism is an obsession of yesterday, replies Rowlands.

Mark Rowlands thinks that my scepticism about moral behaviour in animals is a product of “moral intellectualism”. According to moral intellectualism as Rowlands characterises it, it is necessary for moral behaviour that the agent be able to think about or describe in moral terms what he or she does when he or she acts morally. That is not quite my position. What I think is necessary for moral behaviour is acting for certain kinds of reason, where the reasons operate to produce the relevant behaviour. The reasons need not be explicitly articulable by the agent, though often they can be.
