Possibility, Necessity, and Existence: Abbagnano and His Predecessors by Nino Langiulli (review)

BOOK REVIEWS 503 Possibility, Necessity, and Existence: Abbagnarw and His Predecessors. By NINO LANGIULLI. Philadelphia: Temple University Press, 1992. Pp. xv + 205. $44.95 (cloth). Although Nicola Abbagnano would agree in some sense with the currently fashionable claim that metaphysics is dead, Nino Langiulli's treatment of Abbagnano's thought constitutes a challenge to that claim. The aim, of Possibility, Necessity, and Existence is "to expound and elucidate historically and analytically the concepts of possibility, necessity, and existence as they are refracted through the thought of the twentieth-century Italian philosopher Nicola Abbagnano." Langiulli characterizes Abbagnano as a bold and original thinker whose defense of "possibility" as the fundamental sense of being is understood by Abbagnano himself as an anti-metaphysical position. In his critical reflections, however, especially in the last chapter, Langiulli shows that Abbagnano is indeed engaged in an inquiry that can only be called metaphysical . Parts I and II are preparatory to the third part in which the concept of possibility and its relation to existence are most directly addressed. Part I provides a historical overview of four phases of the movement of Abbagnano's thought "from a positive existentialism to a radical empiricism." Abbagnano's version of existentialism is "positive" in that it sees in human finitude the very possibility of man's relationship with being. Here Abbagnano is distinguished from other existentialists such as Heidegger, Jaspers, Marcel, and Sartre. His criticisms of these positions are among the most important and interesting parts of the book. Heidegger and Jaspers both begin by apprehending human existence as a structure of possibilities but then reduce human existence to a structure of impossibilities. Christian existentialists such as Marcel really treat possibilities as potentialities to be inevitably realized. For Sartre all possibilities are equivalent, but for Abbagnano "the complete arbitrariness of choice among human possibilities does not imply freedom at all, but the impossibility of choice" (18). Here also Langiulli's comparison of Abbagnano with Quine, Sellars, and Rorty is pertinent and illuminating: Abbagnano would share Rorty's criticism of Quine and Sellars for holding on to vestiges of the old empiricism, but Abbagnano would not accept Rorty's "emptying" of philosophy itself. The influence of Abbagnano on his student Umberto Eco and on Gianni Vattimo and the differences between Abbagnano and Derrida's views of possibility are spelled out by Langiulli. In a section entitled "Dumping Philosophy and the Madness of It That Is Also Folly," Langiulli locates Abbagnano clearly and precisely within the debate over the legitimacy of reason. Abbagnano finds the basis of philosophical madness in the persistent tendency to take one aspect of human life as an absolute determinant, thus marginalizing or ignoring all others. "This privileged status has even been attributed to reason, but only when it 504 BOOK REVIEWS is absolutized or divinized as a superhuman force regulating the whole of nature, humanity included, according to necessary and necessitating laws" (39). So, for example, the order of mathematics or the techniques of verification and control employed in physics are transferred to the human world. But Abbagnano's rejection of absolutized reason is not a rejection of reason as such. He sees the current favoring of the nonrational and irrational aspects of life as a kind of folly and madness, "the vertigo of absurdity." The deliberate and crass ignorance of history and the search for novelty are also forms of madness. Part II consists of four chapters that trace the sources for Abbagnano's concept of possibility. The first of these sources is Plato's treatment of existence and possibility in the Sophist, where Abbagnano finds what he takes to be the antecedent for his own thought and for existentialism in general: the idea that possibility is both the structure and the ground of existing things. The two persistent themes of Greek metaphysics that Abbagnano is concerned to overcome are found most explicitly in Aristotle: the priority of actuality over possibility and the primacy of necessity over possibility. Kant is credited with opening the path for contemporary thought with his concept of real possibility (as distinguished from merely logical possibility). Finally, Abbagnano is indebted to Kierkegaard's criticisms of Aristotle and Hegel in the Philosophical...
