Intuitionists

But he differs from intuitionists by discarding appeals to intuition of non-empirical moral truths as "worthless" Ayer, Language, 106 since the intuition of one person often contradicts that of another.

Ethical intuitionists assert that, if we see a good person or a right action, and our faculty of moral intuition is sufficiently developed and unimpaired, we simply intuit that the person is good or that the action is right.

For intuitionists, infinity is described as potential; terms synonymous with this notion are becoming or constructive.

From this springboard, intuitionists seek to reconstruct what they consider to be the corrigible portion of mathematics in accordance with Kantian concepts of being, becoming, intuition, and knowledge.

However, neither moral realism nor ethical non-naturalism are essential to the view; most ethical intuitionists simply happen to hold those views as well.

In general, intuitionists allow the use of the law of excluded middle when it is confined to discourse over finite collections (sets), but not when it is used in discourse over infinite sets (e.g. the natural numbers).

The intuitionists believed that aesthetic experience was disclosed by a single mental faculty of some kind.
