Chwistek was a Polish avant-garde painter, theoretician of modern art, literary critic, logician, philosopher and mathematician.
Chwistek developed his theory of the multiplicity of realities first with regard to the arts. He distinguished four basic types of realities, then matched them with four basic types of painting.
The four types of realities were:
1. popular reality (common-sense realism)
2. physical reality (constructed by physics)
3. phenomenal reality (sensory impressions)
4. visionary/intuitive reality (dreams, hallucinations, subconscious states).
The types of painting corresponding to the above were:
1. Primitivism
2. Realism
3. Impressionism
4. Futurism
