Post-truth is about a historical problem regarding
truth in everyday life, especially politics. But truth has long been one of the major preoccupations of
philosophy. Truth is also one of the most complicated concepts in the history of philosophy, and much of the research and public debate about post-truth assumes a particular theory of truth, what philosophers call a
correspondence theory of truth. The latter might be considered the most prominent theory of truth, though with its share of critics, whereby words correspond to an accepted or mutually available reality to be examined and confirmed. Another major theory of truth is
coherence theory, where truth is not just about one claim but a series of statements that cohere about the world. Several academic experts note that the emphasis on philosophical debates about truth have little to do with the concept of post-truth as it has historically emerged in popular politics (see
post-truth politics), not in philosophy. As the philosopher
Julian Baggini explains: The merits of these competing theories are of mainly academic concern. When people debate whether there were weapons of mass destruction in
Saddam Hussain's Iraq, whether global warming is real and anthropogenic, or whether austerity is necessary, their disagreements are not the consequence of competing theories of truth. No witness need ask a judge which theory she has in mind when asked to promise to tell the truth, the whole truth and nothing but the truth. Why then has truth become so problematic in the world outside academic philosophy? One reason is that there is major disagreement and uncertainty concerning what counts as a reliable
source of truth. For most of human history, there was some stable combination of trust in religious texts and leaders, learned experts and the enduring folk wisdom called
common sense. Now, it seems, virtually nothing is universally taken as an authority. This leaves us having to pick our own experts or simply to trust our guts. It follows that according to experts who approach the concept of post-truth as something historically specific, as a contemporary sociological phenomenon, post-truth theory is only remotely related to traditional debates in philosophy about the nature of truth. In other words, post-truth as a contemporary phenomenon is not about asking "what is truth?" or "is X true?" but "why don't we agree that this or that is true?" A broad range of scholarship increasingly insists a breakdown in institutional authority for truth-telling (government, news media, especially) ushered by
new media and communication technologies of
user-generated content, new media editing technologies (visual, audio-visual), and a saturating promotional culture has resulted in confusion and "games of truth"-telling, even truth markets.
Friedrich Nietzsche Not all commentators, however, treat post-truth as a historically specific phenomenon discussed through implicit correspondence, coherence, or pragmatist theories of truth. They discuss it within a philosophical tradition that asks what truth is.
Friedrich Nietzsche, a 19th-century German philosopher, is sometimes cited in this camp of post-truth commentators. Friedrich Nietzsche is sometimes invoked as a predecessor to theories of post-truth. He argues that humans create the concepts through which they define the good and the just, thereby replacing the concept of truth with the concept of value, and grounding reality in the human will and
will to power. In his 1873 essay
Truth and Lying in an Extra-Moral Sense, Nietzsche holds that humans create truth about the world through their use of
metaphor,
myth, and
poetry. He writes,If someone hides an object behind a bush, then seeks and finds it there, that seeking and finding is not very laudable: but that is the way it is with the seeking and finding of "truth" within the rational sphere. If I define the mammal and then after examining a camel declare, "See, a mammal", a truth is brought to light, but it is of limited value. I mean, it is anthropomorphic through and through and contains not a single point that would be "true in itself" or really and universally valid, apart from man. The investigator into such truths is basically seeking just the metamorphosis of the world into man; he is struggling to understand the world as a human-like thing and acquires at best a feeling of assimilation. According to Nietzsche, all insights and ideas arise from a particular perspective. This means that there are many possible perspectives in which a truth or value judgment can be made. This amounts to declaring that there is no "true" way of seeing the world, but it does not necessarily mean that all perspectives are equally valid. Nietzschean
perspectivism denies that a metaphysical objectivism is anything possible and asserts that there are no objective evaluations capable of transcending any cultural formation or subjective designations. This means that there are no objective facts and that understanding or knowledge of a thing in itself is not possible: Therefore, the truth (and above all the belief in it) is an error, but it is an error necessary for life: "Truth is a kind of error without which a certain kind of living creature would not be able to live".
