or value, it holds that no one has access to an absolute view of the world cut off from perspective. Instead, all such 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.For the perspectivist divergence between truth and value, and its opposition to correspondence theories of truth, see: Including its pre-Nietzschean forms, perspectivism traditionally holds that: "All seeing occurs from some point of view, in accordance with our interests. There is neither a view from nowhere nor a view from everywhere; ..Though we have no absolute view, cut off from the perspective, it does not follow that all perspectives are 'equally valid.' On the contrary, some perspectives are better than others. We know this not because we have the ability to compare perspectives to whatever lies outside any perspective, but because we can (and do) compare perspectives to one another."

' regarding a particular proposition. See especially page 148. 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 , as may the entire philosophical problem of how true knowledge is to penetrate one's perspectival limitations.

Montaigne

Montaigne's philosophy presents in itself a 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 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 "

", he writes:


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 begins by challenging the underlying notions of 'viewing from nowhere', 'viewing from everywhere', and 'viewing without interpreting' as being absurdities. Instead, all 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: 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

. 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

project, that all that has been considered non-perspectival knowledge, the entire tradition of Western metaphysics, has itself been only a perspective.

Here, contemporary scholar Ken Gemes views Nietzsche's perspectivism to above all be a principle of

Later developments


20th century

In the 20th century, perspectivism was discussed separately by
José Ortega y Gasset José Ortega y Gasset (; ; 9 May 1883 – 18 October 1955) was a Spanish philosopher and essayist. He worked during the first half of the 20th century while Spain oscillated between monarchy, republicanism and dictatorship. His philosoph ...

. 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.
