Nature of existentialist thought and manner
According to existentialism: (1) Existence is always particular and individual—always my existence, your existence, his existence. (2) Existence is primarily the problem of existence (i.e., of its mode of being); it is, therefore, also the investigation of the meaning of Being. (3) This investigation is continually faced with diverse possibilities, from among which the existent (i.e., the human individual) must make a selection, to which he must then commit himself. (4) Because these possibilities are constituted by the individual’s relationships with things and with other humans, existence is always a being-in-the-world—i.e., in a concrete and historically determinate situation that limits or conditions choice. Humans are therefore called Dasein (“there being”) because they are defined by the fact that they exist, or are in the world and inhabit it.
With respect to the first point, that existence is particular, existentialism is opposed to any doctrine that views human beings as the manifestation of an absolute or of an infinite substance. It is thus opposed to most forms of idealism, such as those that stress Consciousness, Spirit, Reason, Idea, or Oversoul. Second, it is opposed to any doctrine that sees in human beings some given and complete reality that must be resolved into its elements in order to be known or contemplated. It is thus opposed to any form of objectivism or scientism since these stress the crass reality of external fact. Third, existentialism is opposed to any form of necessitarianism; for existence is constituted by possibilities from among which the individual may choose and through which he can project himself. And, finally, with respect to the fourth point, existentialism is opposed to any solipsism (holding that I alone exist) or any epistemological idealism (holding that the objects of knowledge are mental), because existence, which is the relationship with other beings, always extends beyond itself, toward the being of these entities; it is, so to speak, transcendence.
Starting from these bases, existentialism can take diverse and contrasting directions. It can insist on the transcendence of Being with respect to existence, and, by holding this transcendence to be the origin or foundation of existence, it can thus assume a theistic form. On the other hand, it can hold that human existence, posing itself as a problem, projects itself with absolute freedom, creating itself by itself, thus assuming to itself the function of God. As such, existentialism presents itself as a radical atheism. Or it may insist on the finitude of human existence—i.e., on the limits inherent in its possibilities of projection and choice. As such, existentialism presents itself as a humanism.
From 1940 on, with the diffusion of existentialism through continental Europe, its directions developed in keeping with the diversity of the interests to which they were subject: the religious interest, the metaphysical (or nature of Being) interest, and the moral and political interest. This diversity was rooted, at least in part, in the diversity of sources on which existentialism draws. One such source is the subjectivism of the 4th–5th-century theologian St. Augustine, who exhorted others not to go outside themselves in the quest for truth, for it is within them that truth abides. “If you find that you are by nature mutable,” he wrote, “transcend yourself.” Another source is the Dionysian Romanticism of the 19th-century German philosopher Friedrich Nietzsche, who exalted life in its most irrational and cruel features and made this exaltation the proper task of the “higher man,” who exists beyond good and evil. Still another source is the nihilism of the Russian author Fyodor Dostoyevsky, who, in his novels, presented human beings as continually defeated as a result of their choices and as continually placed before the insoluble enigma of themselves. As a consequence of the diversity of these sources, existentialist doctrines focus on several aspects of existence.
They focus, first, on the problematic character of the human situation, through which the individual is continually confronted with diverse possibilities or alternatives, among which he may choose and on the basis of which he can project his life.
Second, the doctrines focus on the phenomena of this situation and especially on those that are negative or baffling, such as the concern or preoccupation that dominates the individual because of the dependence of all his possibilities upon his relationships with things and with other people; the dread of death or of the failure of his projects; the “shipwreck” upon insurmountable “limit situations” (death, the struggle and suffering inherent in every form of life, the situation in which everyone daily finds himself); the guilt inherent in the limitation of choices and in the responsibilities that derive from making them; the boredom from the repetition of situations; and the absurdity of his dangling between the infinity of his aspirations and the finitude of his possibilities.
Third, the doctrines focus on the intersubjectivity that is inherent in existence and is understood either as a personal relationship between two individuals, I and thou, such that the thou may be another person or God, or as an impersonal relationship between the anonymous mass and the individual self deprived of any authentic communication with others.
Fourth, existentialism focuses on ontology, on some doctrine of the general meaning of Being, which can be approached in any of a number of ways: through the analysis of the temporal structure of existence; through the etymologies of the most common words—on the supposition that in ordinary language Being itself is disclosed, at least partly (and thus is also hidden); through the rational clarification of existence by which it is possible to catch a glimpse, through ciphers or symbols, of the Being of the world, of the soul, and of God; through existential psychoanalysis that makes conscious the fundamental “project” in which existence consists; or, finally, through the analysis of the fundamental modality to which all the aspects of existence conform—i.e., through the analysis of possibility.
There is, in the fifth place, the therapeutic value of existential analysis that permits, on the one hand, the liberating of human existence from the beguilements or debasements to which it is subject in daily life and, on the other, the directing of human existence toward its authenticity—i.e., toward a relationship that is well-grounded on itself, and with other humans, with the world, and with God.
The various forms of existentialism may also be distinguished on the basis of language, which is an indication of the cultural traditions to which they belong and which often explains the differences in terminology among various authors. The principal representatives of German existentialism in the 20th century were Martin Heidegger and Karl Jaspers; those of French personalistic existentialism were Gabriel Marcel and Jean-Paul Sartre; that of French phenomenology were Maurice Merleau-Ponty; that of Spanish existentialism was José Ortega y Gasset; that of Russian idealistic existentialism was Nikolay Berdyayev (who, however, lived half of his adult life in France); and that of Italian existentialism was Nicola Abbagnano. The linguistic differences, however, are not decisive for a determination of philosophical affinities. For example, Marcel and Sartre were farther apart than Heidegger and Sartre; and there was greater affinity between Abbagnano and Merleau-Ponty than between Merleau-Ponty and Marcel.
