Abstract
Research goes through singularity, particularity and universality. It does not depart from an extreme to arrive into the other one (like in the classic agreement induction vs. deduction). In this context, universality is the horizon of science, to achieve this, a subjective dimension is excluded. On the one hand, psychoanalysis has a complex relationship with science: it researches, like science, under the pretension of getting valid assertions for a work community, but, on the other hand, psychoanalysis has its horizon on the radicalization of singularity, under the mandate of putting back the subjectivity excluded on science operations.

Transference to practice
Given its conception on the subject, psychoanalysis allows the research of issues like education in an unique way. For example, Freud thinks education is an impossible enterprise (next to governing and psychoanalyzing): There is something in human uniqueness –drive- that is untamable, there is a “psychic economy” and subject decisions must go through them, beyond those hours of exposition to morals, independently of how they set their objectives. Knowledge, students’ relationship with it, behavior, authority, students’ attitude towards it, interaction… acquire a new meaning.
