We deepen the relationships between main Matte Blanco's ideas and Aristotelian logic, calling into question also phallic logic, after having premised some discussions on the possible intertwinements between logic and psychoanalysis again. Hence, further possible applications to informatics are also considered. In particular, we have outlined possible, first formalizations attempts of the processes involved in the passage from primary to secondary process according to Freudian theory, from a logical viewpoint, with the involvement of phallus logic and the usual Boolean one. Besides this, we conclude the chapter making mention to the so-called affect logic according to Luc Ciompi, with its relationships with natural sciences, as well as to other formalizations of the main psychoanalytic concepts from the topological and quasi-topological perspective, so reaching to identify possible pathways leading to fuzzy logic and other domains of application.
Top7.1 The Possible Relationships Between Psychoanalysis And Logic
In order to understand better the intertwinements between psychoanalysis and logic, as established above all by Matte Blanco, it is useful to briefly discuss the central points of classical logical discipline. First of all, its basic concepts, from the psychological point of view, may be considered as specific mental operations. Among these are the notions of event, object, class, set, affirmation, negation, relation, equation, converse, and so on. For belonging to formal logic, each of these needs a precise definition. In what follows, if not otherwise specified, we mainly refer to (Rayner, 1995).
If logic is considered as a mathematical discipline, then the above concepts should be mentioned together with others of greatest precision, such as unit, quantity, enumeration (counting), addition, subtraction, zero, infinity, point, line, space, rate, rate of change, and so on. From the psychological point of view, these concepts are probably conceived by most people, but only at an intuitive level. Surely the intuitive origins of logical and mathematical concepts can often be detected at the early stages of life. For instance, it has been ascertained that a baby as young as six months can reliably detect the difference for instance between two and three objects, hence to do estimates from the rough comparison between two groups of a few elements.
