In privileging subjective truth, Kierkegaard captures two of the central themes in existentialism. First, to follow one's own truth may require suspending one's universal duty to others. As we will see in more detail in chapter 6, we are all confronted with painful, life-defining moments when we have to choose between being true to objective moral laws or being true to oneself. For the existentialists, it is only the latter choice that manifests ‘the highest truth attainable.’ Second, Kierkegaard shows how theoretical detachment cannot give us access to our own truth. The truth of one's own existence is not thought but felt in penetrating emotional experiences of dread and anguish. These truths are dreadful because they have no objective or rational justification and are, therefore, incomprehensible to others. No one else can understand the commitments that matter to me as an individual. It is important to note, however, that this position does not make Kierkegaard an ‘irrationalist.’ It shows, rather, that rationality and objectivity are only a part of what it means to be human, but when it comes to one's own concrete concerns, it is of little or no use. Subjective truths cannot be reasoned about; they must be lived. This idea, that the ‘highest truths’ emerge out of the situated concerns of the individual, is further developed by Nietzsche, who radicalizes Kierkegaard by rejecting the notion of objective truth altogether and suggesting that all we have access to is our own finite and limited ‘perspective,’ and there is no way to detach or to step outside of it.
Perspectivism
Nietzsche, like Kierkegaard, was highly suspicious of systematic philosophy, largely because it was self-legitimating, that is, it uncritically assumes the truth of a set of principles and then uses these principles to construct the system. On Nietzsche's view, this kind of philosophy is ‘weak’ and ‘dishonest’ because it fails to rigorously question the principles that hold the system together. This is why he proclaims, “I mistrust all systematizers and avoid them. The will to a system is a lack of integrity” (1990, 35). For Nietzsche, metaphysical systems do not reveal the way the world really is because there is no ‘real’ world to begin with. “The ‘apparent’ world is the only one. The ‘real’ world has only been lyingly added …” (46). All systems, whether religious, philosophical, or scientific, are simply human constructions that express a psychological need for stability and control that protects us from the terrifying mutability and impermanence of existence. Indeed, to be human means to already inhabit and tacitly accept a socially constructed perspective that “we cannot see around” (Nietzsche 1995, 374).
Nietzsche's account of the interpretative or perspectival character of existence undermines the assumption that, through a method of rational detachment, the philosopher can attain ‘the perspective of eternity’ and gain knowledge of timeless truths or empirical ‘facts.’ From the point of view of perspectivism, “facts are precisely what there is not, only interpretations. We cannot establish any fact ‘in itself’. … [The world] has no meaning behind it, but countless meanings” (Nietzsche 1968, 481). The upshot of this account is that reality or truth is not discovered by means of reason; it is created. Throughout human history we invent different names for things and then call them true. Nietzsche calls this “the greatest difficulty … [that is] to recognize that unspeakably more depends on what things are called than on what they are” (1995, 58). Truths are viewed as “a mobile army of metaphors” that are invented and that continue to endure only insofar as they are “useful” (1954b, 46–47). They are passed down from generation to generation until they become “worn out” (47) and uncritically accepted as fact. Today, for instance, Euro-Americans generally accept the democratic ideals of equality, justice, and individual rights. But in Nietzsche's view, these are just calcified interpretations that have emerged historically from a contingent series of events that happened to take hold of the public imagination several centuries ago and over time came to be uncritically regarded as true. This is why Nietzsche says, “That you perceive something as [true] may be caused by the fact that you have never reflected on yourself, and are blindly accepting what has been designated as right to you since childhood” (1995, 335).
This means, of course, that consciousness itself is a social construction. All of our so-called inner beliefs, values, and thoughts are shaped by a particular sociohistorical perspective, and we can make sense of ourselves — and the social roles that we play — only in terms of this perspective. In this sense, our thoughts are not our own because consciousness does not belong to us. In order to have a thought, a need, or a desire we must have a word for it, because “all consciousness occurs in words” (354). Consciousness, therefore, is conditioned by a social world and the linguistic conventions that shape it. Nietzsche explains:
My thought is … that consciousness does not really belong to the individual existence of human beings, but rather to the social and herd nature in them; that, as a consequence, consciousness is subtly developed only in regard to social and herd usefulness, and consequently each of us, despite the best will to understand oneself as individually as possible, ‘to know oneself,’ will always just bring to one's consciousness precisely what is not individual in one. (354)
For Nietzsche, growing into social conventions in the way that we do has resulted in a standardized, leveled-down, and conformist consciousness, where “everything that becomes conscious becomes, by the same token, shallow, thin, relatively stupid, general … a signal of the herd” (354). With the conformity of herd consciousness, everything “strange, unusual, questionable, [and] disturbing” is explained and understood against the secure and stable backdrop of what is familiar and known. Nietzsche calls this the “instinct of fear” (355). It is flight from the horror that our perspectives are not secure and timeless but historically contingent and that there are innumerable ways of knowing the world, and this makes us afraid to question what we know, namely, the perspective that is most comforting and “familiar to us” (355).
To be sure, perspectivism serves important psychological and social functions because it allows us to arrange and make sense of an otherwise frightening and absurd existence. This is why Nietzsche says, “Truth is that sort of error without which a certain species of life could not live” (1968, 293). His critical aim, then, is not to deny the social utility of our belief in truth but to come to grips with the fact that the alleged stability and permanence of our truths is an “illusion” (1996, III, 24). Here, Nietzsche captures an important theme that will take center stage in twentieth-century incarnations of existential phenomenology: the idea that philosophy always begins from within the particular, embodied, sociohistorical context we grow into, a context that cannot be represented or explained by means of detachment and objectivity. This is because all rational explanations are parasitic on our own situated existence. As Heidegger will later write: “The existential nature of man is the reason why man can represent beings as such and why he can be conscious of them. All consciousness presupposes … existence as the essential of man” (1956, 205). And if an objective explanation of existence is impossible, then the best we can do is describe our experience as it ‘appears to us.’
Phenomenology
Inaugurated by Edmund Husserl (1859–1938) in 1900, the method of phenomenology was conceived as a return ‘to the things themselves.’ Rather than trying to systematically explain ‘what things are’ in terms of their material or psychic composition, phenomenology is a method that is concerned with describing ‘how things are,’ that is, how things reveal themselves or appear to us in ordinary experience. Phenomenology, then, is the science of phenomena, where ‘phenomena’ refers to that which appears, shows up, or is given to us in the immediacy of our everyday lives. This does not mean that appearances are somehow different from the way things really are. Phenomenology is not concerned with the traditional philosophical problem of discovering the enduring essence or reality that is hidden behind the flux of appearances. Indeed, the core epistemological distinction between ‘appearance’ and ‘reality’ is rejected altogether. Phenomenology is concerned simply with the phenomenon as it appears, as it “shows itself in itself” (Heidegger 1962, 51). The aim is to show that there is no reality or ‘thing-in-itself’ to be found behind the appearance. Indeed, the method of phenomenology demonstrates that appearances (or phenomena) are the things themselves. “This is why,” as Sartre explains, “we reject the dualism of appearance and essence. The appearance does not hide the essence, it reveals it; it is the essence” (1956, 4–5).
