Questioning moral certainty › What a perspective changes

A perspective is an orientation that affects what becomes salient, which questions are asked, and how an answer is interpreted. “Perspectivism” names a family of readings of Nietzsche's account of knowledge; the book does not present it as a finished theory with a single formal statement. Its arguments repeatedly question whether philosophers can describe the world without interpretation.

In §14 Nietzsche calls physics an interpretation and arrangement of the world rather than a final explanation of it. In §22 he challenges the language of nature's conformity to laws. He imagines another interpreter describing the same regularities through the unrestricted exercise of power. The alternative need not change the claim that events have a necessary and calculable course. It changes the conceptual story about what that regularity means.

His point therefore cannot simply be that the physical observations are whatever an observer wants. The imagined interpreters share phenomena to be explained. They disagree about the framework through which those phenomena become intelligible. At the end of §22 Nietzsche anticipates the reply that his proposed account is itself an interpretation, and accepts the description. His challenge turns back upon his own philosophy.

The book's perspective-sensitive arguments do not establish that every belief is equally good. Nietzsche continually distinguishes interpretations and valuations, often sharply. Nor should “relativism” be defined as nothing more than treating all beliefs as equally valid; philosophical positions called relativist vary considerably. The useful question here is what grounds a judgment between interpretations once a wholly uninterpreted standpoint has been challenged.

Consider a hypothetical dispute over a school's examination results. One observer sees improved performance; another asks whether the examination rewards too narrow a range of abilities. They might agree about every score and still disagree about what counts as educational achievement. Identifying their perspectives makes the disagreement clearer. It does not determine whether either examination policy is justified, or excuse a false report of the scores.

This example illustrates a distinction; it is not Nietzsche's example or evidence about actual schools. It also exposes a limit to suspicion. If every unwelcome result is dismissed as merely someone else's perspective, inquiry loses the ability to correct itself. A defensible perspective must remain answerable to objections and to the material it claims to interpret.
