Sigmund Freud (1856–1939) who defined psychoanalysis can also be considered a vordenker of fauceir theory. At least, he discovered two important feature among psychological fauceirs that are crucial to all fauceirs.
- Property inheritance. (Inheritance is not meant as inheritance from parents to children, but in the sense of inheritance of encapsulated psychological fauceirs in an evolving mind.)
- Enslavement. He called it repression, Verdrängung.

It has to be criticized, however, that he focused inheritance and repression on sexual experiences only. But there is a myriad of fauceirs that show the same behavior, not all of them subconscious. Also consciously, stories, the units by which reality is memorized, are altered to fit a higher level fauceir, a theory for instance.
