Externism

This character appears in many plays by authors from the Jára Cimrman Theatre in Prague.

The first act of the theatre performance is usually filled with a lecture on Cimrman's personality, followed by a theatrical play.

The theory of externism is described in a monologue by a Cimrmanologist having a lecture on Jára Cimrman's significance in the field of philosophy in the first act of the theatre play Akt (The Nude) by Zdeněk Svěrák, Ladislav Smoljak and Jiří Šebánek.

He compared the world to a space with a small place in the middle, where Jára Cimrman is missing.

Later Cimrman elaborated the theory in more detail, as Cimrmanologists found out when reading Albert Einstein's correspondence.

Albert Einstein considered the theory to be "funny", which Cimrmanologists read as an expression of admiration.

According to this vulgar materialist (which also means "pharmacist" in Czech), the truth is the basic principle of our knowledge.

Cimrman stated that at the beginning of every learning process, our knowledge is formed by a mistake, which is precise, and we must refute it.
