Intutitionist theory. Ethics as intuitions.
Ross accepted G. E. Moore's argument that any equation of intrinsic good with a natural property commits the 'naturalistic fallacy'. However, Ross argues that Moore committed a similar fallacy in equating the rightness of an action with its maximization of good. That we ought always to maximize good is a synthetic and, in fact, false proposition. We have a number of distinct prima-facie obligations, of which this is only one and not always the most stringent. An act may be prima facie obligatory for a number of different reasons, and is absolutely right if the prima-facie obligation to do it is the weightiest. His attack on consequentialism and notion of a prima-facie moral obligation has had an enduring influence. OCP
