# Perspectivism

Perspectivism (also called perspectivalism) is the epistemological principle that perception of and knowledge of something are always bound to the interpretive perspectives of those observing it. While perspectivism does not regard all perspectives and interpretations as being of equal truth or value, it holds that no one has access to an absolute view of the world cut off from perspective. Instead, all such viewing occurs from some point of view which in turn affects how things are perceived. Rather than attempt to determine truth by correspondence to things outside any perspective, perspectivism thus generally seeks to determine truth by comparing and evaluating perspectives among themselves. Perspectivism may be regarded as an early form of epistemological pluralism, though in some accounts includes treatment of value theory, moral psychology, and realist metaphysics.
Early forms of perspectivism have been identified in the philosophies of Protagoras, Michel de Montaigne, and Gottfried Leibniz. However, its first major statement is considered to be Friedrich Nietzsche's development of the concept in the 19th century, influenced by Gustav Teichmüller's use of the term some years prior. For Nietzsche, perspectivism takes the form of a realist antimetaphysics while rejecting both the correspondence theory of truth and the notion that the truth-value of a belief always constitutes its ultimate worth-value. The perspectival conception of objectivity used by Nietzsche sees the deficiencies of each perspective as remediable by an asymptotic study of the differences between them. This stands in contrast to Platonic notions in which objective truth is seen to reside in a wholly non-perspectival domain.
According to Alexander Nehamas, perspectivism is often misinterpreted as a form of relativism, whereby we acknowledge the true virtue of fully rejecting the 'Law of excluded middle' regarding a particular proposition. Lacewing Michael adds that although perspectivism doesn't accede to an objective view of the world that is detached from our subjectivity, our assessment of reality can still approach "objectivity" subjectively and asymptotically. Nehamas also describes how perspectivism does not prohibit someone from holding some interpretations to be definitively true. It only alerts us that we cannot objectively determine the truth from outside our perspective. The idea that perspectivism is an absolutely true thesis, is called weak perspectivism by Brian Lightbody.
The basic principle that things are perceived differently from different perspectives (or that perspective determines one's limited and unprivileged access to knowledge) has sometimes been accounted as a rudimentary, uncontentious form of perspectivism. The basic practice of comparing contradictory perspectives to one another may also be considered one such form of perspectivism (See also: Intersubjectivity), as may the entire philosophical problem of how true knowledge is to penetrate one's perspectival limitations.

## Precursors and early developments

In Western languages, scholars have found perspectivism in the philosophies of Heraclitus (c. 540 – c. 480 BCE), Protagoras (c. 490 – c. 420 BCE), Michel de Montaigne (1533 – 1592 CE), and Gottfried Leibniz (1646 – 1716 CE). The origins of perspectivism have also been found to lie also within Renaissance developments in philosophy of art and its artistic notion of perspective. In Asian languages, scholars have found perspectivism in Buddhist, Jain, and Daoist texts. Anthropologists have found a kind of perspectivism in the thinking of some indigenous peoples. Some theologians believe John Calvin interpreted various scriptures in a perspectivist manner.

### Ancient Greek philosophy

The Western origins of perspectivism can be found in the pre-Socratic philosophies of Heraclitus and Protagoras. In fact, a major cornerstone of Plato's philosophy is his rejection and opposition to perspectivism—this forming a principal element of his aesthetics, ethics, epistemology, and theology. The antiperspectivism of Plato made him a central target of critique for later perspectival philosophers such as Nietzsche.

### Montaigne

Montaigne's philosophy presents in itself a perspectivism less as a doctrinaire position than as a core philosophical approach put into practice. Inasmuch as no one can occupy a God's-eye view, Montaigne holds that no one has access to a view which is totally unbiased, which does not interpret according to its own perspective. It is instead only the underlying psychological biases which view one's own perspective as unbiased. In a passage from his "Of Cannibals", he writes:
   Men of intelligence notice more things and view them more carefully, but they [interpret] them; and to establish and substantiate their interpretation, they cannot refrain from altering the facts a little. They never present things just as they are but twist and disguise them to conform to the point of view from which they have seen them; and to gain credence for their opinion and make it attractive, they do not mind adding something of their own, or extending and amplifying.

## Nietzsche

In his works, Nietzsche makes a number of statements on perspective which at times contrast each other throughout the development of his philosophy. Nietzsche's perspectivism begins by challenging the underlying notions of 'viewing from nowhere', 'viewing from everywhere', and 'viewing without interpreting' as being absurdities. Instead, all viewing is attached to some perspective, and all viewers are limited in some sense to the perspectives at their command. In The Genealogy of Morals he writes:
   Let us be on guard against the dangerous old conceptual fiction that posited a 'pure, will-less, painless, timeless knowing subject'; let us guard against the snares of such contradictory concepts as 'pure reason', 'absolute spirituality', 'knowledge in itself': these always demand that we should think of an eye that is completely unthinkable, an eye turned in no particular direction, in which the active and interpreting forces, through which alone seeing becomes seeing something, are supposed to be lacking; these always demand of the eye an absurdity and a nonsense. There is only a perspective seeing, only a perspective knowing; and the more affects we allow to speak about one thing, the more eyes, different eyes, we can use to observe one thing, the more complete will our 'concept' of this thing, our 'objectivity' be.
In this, Nietzsche takes a contextualist approach which rejects any God's-eye view of the world. This has been further linked to his notion of the death of God and the dangers of a resulting relativism. However, Nietzsche's perspectivism itself stands in sharp contrast to any such relativism. In outlining his perspectivism, Nietzsche rejects those who claim everything to be subjective, by disassembling the notion of the subject as itself a mere invention and interpretation. He further states that, since the two are mutually dependent on each other, the collapse of the God's-eye view causes also the notion of the thing-in-itself to fall apart with it. Nietzsche views this collapse to reveal, through his genealogical project, that all that has been considered non-perspectival knowledge, the entire tradition of Western metaphysics, has itself been only a perspective. His perspectivism and genealogical project are further integrated into each other in addressing the psychological drives that underlie various philosophical programs and perspectives, as a form of critique. Here, contemporary scholar Ken Gemes views Nietzsche's perspectivism to above all be a principle of moral psychology, rejecting interpretations of it as an epistemological thesis outrightly. It is through this method of critique that the deficiencies of various perspectives can be alleviated—through a critical mediation of the differences between them rather than any appeals to the non-perspectival. In a posthumously published aphorism from The Will to Power, Nietzsche writes:
   "Everything is subjective," you say; but even this is interpretation. The "subject" is not something given, it is something added and invented and projected behind what there is.—Finally, is it necessary to posit an interpreter behind the interpretation? Even this is invention, hypothesis.
   In so far as the word "knowledge" has any meaning, the world is knowable; but it is interpretable otherwise, it has no meaning behind it, but countless meanings.—"Perspectivism."
   It is our needs that interpret the world; our drives and their For and Against. Every drive is a kind of lust to rule; each one has its perspective that it would like to compel all the other drives to accept as a norm.
While Nietzsche does not plainly reject truth and objectivity, he does reject the notions of absolute truth, external facts, and non-perspectival objectivity.

### Truth theory and the value of truth

Despite receiving much attention within contemporary philosophy, there is no academic consensus on Nietzsche's conception of truth. While his perspectivism presents a number of challenges regarding the nature of truth, its more controversial element lies in its questioning of the value of truth. Contemporary scholars Steven D. Hales and Robert C. Welshon write that:
   Nietzsche's writings on truth are among the most elusive and difficult ones in his corpus. One indication of their obscurity is that on an initial reading he appears either blatantly inconsistent in his use of the words 'true' and 'truth', or subject to inexplicable vacillations on the value of truth.

## Later developments
### 20th century

In the 20th century, perspectivism was discussed separately by José Ortega y Gasset and Karl Jaspers. Ortega's perspectivism, replaced his previous position that "man is completely social". His reversal is prominent in his work Verdad y perspectiva ("Truth and perspective"), where he explained that "each man has a mission of truth" and that what he sees of reality no other eye sees. He explained:
   From different positions two people see the same surroundings. However, they do not see the same thing. Their different positions mean that the surroundings are organized in a different way: what is in the foreground for one may be in the background for another. Furthermore, as things are hidden one behind another, each person will see something that the other may not.
Ortega also maintained that perspective is perfected by the multiplication of its viewpoints. He noted that war transpires due to the lack of perspective and failure to see the larger contexts of the actions among nations. Ortega also cited the importance of phenomenology in perspectivism as he argued against speculation and the importance of concrete evidence in understanding truth and reality. In this discourse, he highlighted the role of "circumstance" in finding out the truth since it allows us to understand realities beyond ourselves.

### 21st century

During the 21st century, perspectivism has led a number of developments within analytic philosophy and philosophy of science, particularly under the early influence of Ronald Giere, Jay Rosenberg, Ernest Sosa, and others. This contemporary form of perspectivism, also known as scientific perspectivism, is more narrowly focused than prior forms—centering on the perspectival limitations of scientific models, theories, observations, and focused interest, while remaining more compatible for example with Kantian philosophy and correspondence theories of truth. Furthermore, scientific perspecitivism has come to address a number of scientific fields such as physics, biology, cognitive neuroscience, and medicine, as well as interdisciplinarity and philosophy of time. Studies of perspectivism have also been introduced into contemporary anthropology, initially through the influence of Eduardo Viveiros de Castro and his research into indigenous cultures of South America.
