Abstract: Abstract In this paper the authors analyze the pattern of reasoning in schizophrenia, according to proof theory. In particular they consider the clinical form of “organized” (paranoid subtype) and “disorganized” schizophrenia. In the first form they focusing on the conservation and an “excess” of the use of standard inference rules that formalize certain logical modes of reasoning, but also the incorrect use of premises not context sensitive. The authors also suggest that in disorganized subtype the inference rules are not derived from a tautological proposition, but the patient use non-standard inference rules like assonance, analogy and metaphor, relative to a particular focalized and pervasive mental state. In these case the premises and conclusion of reasoning are represented by a formalized logic expression
