The formal logic configures some connected models when facing and subjecting truth and continuous linear causality based on concepts of substance. Herein the "lottery", the "stray bullet" and the pain are understood as expressions from discontinuity and "chance" linked to a causality that goes further than the immediate relationship established between the intentionality of the subject presented in the cause and effect. The discontinuous and undecided logical allows questioning about the non-casual logical and about the statute of the effect, extending so the listening work concerning the pain and the therapeutic practice.
