Plato already suggested that philosophy has to do with death: the task of the philosopher is an exercise-for-death, both theoretical and practical. And if then Spinoza, in polite but resolute opposition, could affirm that philosophy was «non mortis, sed vitae meditatio», it is above all because that proposition has, as its subject, the free, wise, man who has already won his struggle against death (against his idea), and so he can act with a confidence that comes to him from a divine, imperturbable, non-mortal science. These two positions, apparently conflicting, finally converge at least in recognizing death's place, even if it is negative. Based on those reflections, Carlo Angelino (1938-2022) proposed, in an intense discussion with the great philosophical, religious, and literary traditions, an antithetical thought. The aim of this talk is therefore to briefly illustrate the main lines of Angelino's discourse, firstly tracing his cultural and theoretical references, with particular regard to Plato, Nietzsche, and Heidegger. Then, secondly, to show how the essential point of that reflection is precisely the thought of death, and that it remains so, only explored in all its abyssal depth, or ambiguity, from the writings contained in "Religione e filosofia" (1983) up to the comprehensive, latest collection "L'essere e/o il male" (2018). Searching, with Heidegger, for a new, different beginning for philosophy, he found it not in Being, but in Evil. From that perspective, only knowledge of finiteness could be conceived, as a mortal knowledge in constant antithetical relationship with that other part - the part of mystery, as opposed to that of certainty - that also constructs reality: evil and good, finite and eternal, death and immortality are the antithetical poles of all human experience. Contracted, these terms suggest a space of the religious, a God who is no longer Gott als Geist (and Geist als Gott), «sibbene Gott als Tod e Tod als Gott».
