The biography of a person allows us to reconstruct his lifestyle, his personality, and this finds correspondence in his thought. The early recollections which, according to Adler, can provide valuable clues like projective tests and dreams cannot be considered a biography and, especially if taken from multiple sources, must be carefully screened and verified. If you don't do it, the Individual Psychology is banalized and discredited. Similarly, the important assessment of the position in the family constellation cannot be simplistically transferred to the fruitful contrast of ideas between Freud and Adler, especially now that there is documentary evidence of their debate and the schism of the psychoanalytic movement.
