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.
