REIS, Róbson Ramos dos. Aspects of formal indicative thought: negation and justification. Nat. hum. [online]. 2011, vol.13, n.1, pp. 117-133. ISSN 1517-2430.

According to Heidegger, philosophical concepts have a formal-indicative meaning and the linguistic expression of these concepts results in propositions described as hermeneutic indications ( hermeneutischen Indikationen). Therefore, the formulation and justification of such a kind of sentences allow the introduction of formal-indicative notion of thought. In this paper, we examine two aspects of the formal-indicative thought: its negation and justification. Based on the problem of the origin of negation, presented by Heidegger in Was ist Metaphysik?, we sustain the hypothesis that in formal-indicative thought negation reveals a specific showing function that can be focused by approaching negation as a nihilating comportment instead of as a formal operation. This aspect allows us to introduce the question of the justification in formal indications from a non inferential point of view, but centered in a testimonial aspect which has to be linked with an apophatic and sigetic component of philosophical thought.
