Philosophy Lexicon of Arguments

Intuitionism: A) intuitionism in mathematics assumes that the objects to be inspected, e.g. numbers are only constructed in the process of the investigation and are therefore not finished objects, which are discovered. This has an effect on the double negation and the sentence of the excluded middle.
B) Intuitionism of ethics assumes that moral principles are fixed and are immediately (or intuitively) knowable.
