George A. Kelly, a psychologist born in Kansas, began to elaborate personal construct theory in the first half of the twentieth century; Humberto R. Maturana, a Chilean biologist, started to conceive his theory of autopoiesis during the second half of the same century. The two were unknown to each other, yet their theories show striking similarities. Though the focus of convenience of personal construct theory is psychotherapy whereas the theory of autopoiesis is a biological theory of knowledge, Kelly’s ingenious ideas can be enriched by the way in which Maturana deals with features common to both theories.
