n.
In metaethics, a form of cognitivism that holds that moral statements can be known to be true or false immediately through a kind of rational intuition.
In the 17th and 18th centuries, intuitionism was defended by Ralph Cudworth , Henry More (161487), Samuel Clarke (16751729), and Richard Price (172391); in the 20th century its supporters included H.A Prichard (18711947), G.E. Moore , and David Ross . Intuitionists have differed over the kinds of moral truths that are amenable to direct apprehension. For example, whereas Moore thought that it is self-evident that certain things are morally valuable, Ross thought that we know immediately that it is our duty to do acts of a certain type.
