This short article attempts to overcome the destructive polarization in psychoanalysis today between those who characterize psychoanalysis as a branch of the humanities and those who designate it a science. The author proposes that "Bohr's epistemological device of complementarity" can be used to resolve this problem. He demonstrates that it is not enough to be concerned with the meaning of things, as for instance Schafer is, since the basis of psychoanalysis concerns affects; without understanding the affectual component, the meaning of things themselves is meaningless. In this context he very succinctly summarizes the problem: "… affects signify simultaneously what is historically meaningful and what is or has been biologically purposeful." Thus, to return to the author's original assertion, complementarity prevents the polarization between psychoanalysis as a science and psychoanalysis as a branch of the humanities.
