Ignacio Matte Blanco (October 3, 1908 – January 11, 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.
