Ignacio Matte Blanco (3 October 1908 – 11 January 1995) was a Chilean psychiatrist and psychoanalyst who developed a logic-based explanation for the operation of the unconscious, and for the non-logical aspects of experience. In applying the complexity and paradoxes of mathematical logic to psychoanalysis, he pioneered a coherent way of understanding the clinical situation. He has an international following that includes physicists, mathematicians, cyber-scientists, psychologists, mathematical philosophers, neuroscientists, theologians, linguistics and literary scholars.
Life Matte Blanco was born in Santiago, Chile. He was educated in Chile and qualified there as a medical doctor. He entered psychoanalysis with Fernando Allende Navarro, Latin America's first qualified psychoanalyst. Having moved to London in 1933, he trained in psychiatry at South London's Maudsley Hospital and in psychoanalysis at the British Psychoanalytical Society where he was supervised by Anna Freud and James Strachey, becoming a member of the British Society in 1938. He subsequently worked in the United States, from 1940. He returned to Chile in 1943 where he co-founded the Psychoanalytic Society. In 1966 he travelled to Italy, never to return to his homeland. He settled in Rome with his family. He died there at the age of 86.
The unconscious Matte Blanco argues that in the unconscious "a part can represent the whole" and that "past, present, and future are all the same"'. He set out to examine the five characteristics of the unconscious that Freud had outlined: timelessness, displacement, condensation, replacement of external by internal reality, and absence of mutual contradiction. Matte Blanco hypothesized the nature of unconscious logic, as opposed to conscious logic. He deduced that if the unconscious has consistent characteristics it must follow rules, or there would be chaos. However the nature of these hypothetical characteristics indicates that their rules differ from conventional logic. In his work The Unconscious as Infinite Sets, Matte Blanco proposes that the structure of the unconscious can be summarised by the principles of Generalisation and of Symmetry: 1) The principle of Generalization: here logic does not take account of individuals as such, it deals with them only as members of classes, and of classes of classes. 2) The principle of Symmetry: here the logic treats the converse of any relation as identical to it; that is, it deals with relationships as symmetrical'. While the principle of Generalisation might be compatible with conventional logic, discontinuity is introduced by the principle of Symmetry under which relationships are treated as symmetrical, or reversible. Whereas asymmetrical thinking distinguishes individuals from one another by the relationship between them, reality testing, symmetrical thinking, by contrast, sees relations as holding indiscriminately across a field of individuals. For example, an asymmetrical relationship, X is greater than Y, becomes reversible so that Y is simultaneously greater and smaller than X. Matte Blanco draws here on Klein's understanding that "I am angry (with a person or thing)" as very close to "Someone or something is very angry with me"; and indeed he suggests that Klein was the most creative and original of all those who have drawn inspiration from Freud, highlighting in particular her famous concept of projective identification. For Matte Blanco, "unconsciousness" is marked by symmetry, where there is a tendency towards 'sameness' and likewise, an implicit aversion to 'difference', while the quality of ego-functioning registers and bears difference, in a sense he called asymmetry .
The symmetrical and the asymmetrical Matte Blanco divided the unconscious into two modes of being: the symmetrical and the asymmetrical. Asymmetrical relations are relations that are non reversible. For example, “Jack reads the newspaper” cannot be reversed to the newspaper reading Jack. In this way, asymmetrical relations are logical relations and underlie everyday logic and common sense. They govern the conscious sphere of the human mind. Symmetrical relations, on the other hand, move in both directions simultaneously. For example, 'Daniel sits on a stone' can be reversed as, 'a stone sits on Daniel', without being untrue. Symmetrical relations, govern the unconscious mind. Matte Blanco states that the symmetrical, unconscious realm is the natural state of man and is a massive and infinite presence while the asymmetrical, conscious realm is a small product of it. This is why the principle of symmetry is all-encompassing and can dissolve all logic, leading to the asymmetrical relations perfectly symmetrical. To show the illogical nature of symmetry, Matte Blanco said: "In the thought system of symmetry, time does not exist. An event that occurred yesterday can also occur today or tomorrow. Traumatic events of the past are not only seen in the unconscious as ever present and permanently happening but also about to happen." He said that "We are always, in a given mental product, confronted by a mixture of the logic of the unconscious with that of the preconscious and consciousness". Matte Blanco gives this mixture of two logics the name bi-logic and points out that our thinking is usually bi-logical, expressing the both types of logic to differing extents.
