The Commens Dictionary

Quote from ‘One, Two, Three: Fundamental Categories of Thought and of Nature’


There may be a mere relation of reason between the sign and the thing signified; in that case the sign is an icon. Or there may be a direct physical connection; in that case, the sign is an index. Or there may be a relation which consists in the fact that the mind associates the sign with its object; in that case the sign is a name.

W 5:245
