Utopian socialism is a label used to define the first currents of modern
socialist thought as exemplified by the work of
Henri de Saint-Simon,
Charles Fourier, and
Robert Owen. Utopian socialism is often described as the presentation of visions and outlines for imaginary or futuristic ideal societies, with positive ideals being the main reason for moving society in such a direction. Later socialists and critics of utopian socialism viewed "utopian socialism" as not being grounded in actual material conditions of existing society, and in some cases, as reactionary. These visions of ideal societies competed with
Marxist-inspired revolutionary social democratic movements.
