Psychological determinism

Psychological determinism is the view that psychological phenomena are determined by factors outside of a person's control.
Daniel Bader discusses two forms of psychological determinism:

Orectic psychological determinism is the view that we always act upon our greatest drive. This is often called psychological hedonism, and if the drive is specified for self-interest, psychological egoism.
Rational psychological determinism claims that we always act according to our "strongest" or "best" reason.
