The author draws from Evandro Agazzi’s concept of the epistemology of psychological sciences to define the essential elements that guarantee the scientific basis of the term. What the author deduces from the Professor’s philosophy is the need to define the object of a science, the standards of its protocolary nature; in other words, the collection of data and the rigorousness of the concept itself. With all this in mind, the author argues that a discipline such as psychoanalysis can be defined as scientific in so far as its specific content is clear. This is true even if this type of science differs from the physical-mathematical methodologies that distinguish the sciences that are based on physics/maths, and that claim to be the only worthy sciences, thus diminishing the scientific basis of psychoanalysis, leading to a sort of reductionism. From this viewpoint, the author has gathered a number of methodologies and theoretical concepts proving that psychoanalytic intervention abides by the rules of scientificity.
