Forms

idéalisme m (plural idéalismes)[1]

Etymology

It is formed from French idéal + -isme.[2][3][4] Bloch and Wartburg list it among the derivatives of the base, which is from Late Latin ideālis, taken in 1578 to serve as an adjective for some senses of idée.[5] Littré derives it instead from the verb idéaliser.[6]

Earliest recorded meaning

Diderot used it in 1749, in the Lettre sur les aveugles, for a philosophical doctrine that reduces existence to thought.[2][7]

Semantic evolution

The word first belonged to philosophy, for any system that brings being back to thought and things back to the mind;[7][4] idéalisme transcendantal was said of Kant's philosophy from 1801.[7][4] In 1828 Villemain applied it to literature and the arts, for a view that makes the portrayal of an idealized nature the aim of art, in contrast with realism and naturalism.[2][7]

In common use, from Renan (1863), it named an attitude that subordinates thought and conduct to an ideal.[2][7] A pejorative use followed in Romain Rolland (1904), for a tendency to neglect reality and live on illusions.[7][8]
