Abstract
The article, focused on the Giorgio Agamben’s research methodology, deals with the concept of the threshold of indifference aiming to deepen its meaning and strategic function. Therefore it is an investigation into the author’s unsaid. Starting from the hypothesis that this Agamben’s concept is the result of the engagement of the reflection of Gilles Deleuze, real stone guest of Agambenian studies, on that of Walter Benjamin, the comparison has been started with the operators who seem to preside over the Benjaminian threshold (the dialectics at a standstill) and the Deleuzian zone of indiscernibility (the disjunctive synthesis). Introduced in this philosophical context, the threshold of indifference came to be delineated as a tactic of the immanation, as a tactic of the tertium datur, the third included: an intensive and non-substantial third, which results from the de-identification of the terms of dichotomies and binary relations as a new starting point.
