Scientific production in psychology, especially in intersection with neurobiology, encompasses a vast array of methodologically impeccable works, rigorous research, and sophisticated statistical elaborations. Often, however, these publications demonstrate a narrow scope, a limited perspective, and do not appear to possess significant implications in our daily lives, nor sufficient scientific robustness. This tendency towards fragmentation of knowledge in postmodern sciences may reflect what Francois Lyotard (1979) defined as a short-range plural rationality, with fluid and reversible legitimations. Fortunately, Mark Solms' The Hidden Spring is a text that does not conform to this logic; furthermore, it offers something new: the desired exception. It is a book that broadens horizons, both personal and in knowledge, in constructing a model (starting from the neuropsychoanalytic one) that can guide both clinical practice and research.
