Da Fórmula Porchat: conflito das filosofias, vontade de incredulidade, decidibilidade

The Porchat Formula — i.e., the intuition of an undecidable conflict of philosophies - has both propaedeutic and compulsory role for a non-dogmatic treatment of the history of philosophical systems. While acknowledging such a role, the present article intends to point out to the problematic character of the supposed correspondence between “conflict of philosophies” and “philosophical undecidability”. To this end, it maintains that the feeling of philosophical undecidability has as its unthinking reference a kind of nostalgia for decidability. The article suggests abandoning the topic of undecidability as a false philosophical problem and sustains the need to consider the effects of philosophical practice on the configuration of ordinary life and to take such effects as forms of decidability. For this it is necessary to consider philosophical activity as inscribed in the larger field of the manufacture of human experience.
