This paper aims at explaining and defending some of Cora Diamond's thinking about the role of a kind of guides to thinking about ethics. Aids to thinking of this type can take a very general form but can also be applied in context‐sensitive ways. Maria Balaska has raised the question whether Diamond manages to avoid relativism. Oskari Kuusela also criticises Diamond, focussing on whether talk of human equality can be said to correspond to reality. I will consider these objections in (...) turn and try to show that Diamond is not committed either intentionally or otherwise to relativism. (shrink)
