 Instead, they are ‘grasped by an intuitive act of human reason’ (FE 3). ‘The use of the senses, and the physical sciences, give us no propositions in which ‘right’ or ‘obligatory’ occurs as a term’ (KT 87). There are ‘two types of predicate—those that can be discovered by experience to belong to their subjects, and those that can be discovered by insight, and let us grant that rightness belongs to the second class’ (KT 81). In science, ‘sense-experience…furnishes…real data’ (RG 40). In ethics, ‘no such appeal is possible. We have no more direct way of access to the facts about rightness and goodness and about what things are right or good, than by thinking about them’ (RG 40; emphasis added; also 82).
