The author is concerned with steering existentialism in a positive direction, making it at once more rigorous as to method and more genuinely relevant to the human situation. In arguing that possibility is the fundamental mode and sense of human reality, he challenges the positions of other existentialists who, though they employ the concept of the possible as the basic tool of philosophical analysis, do so incoherently. By a careful and consistent use of this concept, he clarifies its relations with those of inquiry, commitment, time, freedom and death. Critical Existentialism by Nicola Abbagnano.
