According to Leon Chwistek, there are four kinds of reality:
First, there is popular reality...also known as common sense. The sun comes up in the east and sets in the west – everyone knows that!


Fourth, and last, there is visionary reality...this is what we think we know from dreams, religious revelation, hallucinations. For example, you could dream that each day there was a brand new sun, rising dripping gold from waters surrounding the world, and plunging to its death at night.
Did Chwistek think that all of these kinds of reality were equally...real? Probably not. This Polish man, born on this date in 1884, was a university professor of logic, and he explored the philosophy of science as well as mathematics.
But he was also an avant-garde painter and a critic of literature and art.
And his four types of reality mapped onto four types of painting:
1- Primitivism

3- Impressionism

4- Futurism

Umberto Boccioni, Elasticity |
In other aspects of his all his various sorts of work, Chwistek defended common sense and physical reality over the claims of metaphysics and religions. To point out that people use the word “real” and “reality” in these various ways doesn't mean that all of these things ARE real!
Here are a few of my favorite Chwistek pieces:

It's unusual to have a mathematician / logician / philosopher who is also a painter / art theorist!
