Perspectivism () is the term coined by Friedrich Nietzsche in developing the philosophical view (touched upon as far back as Plato's rendition of Protagoras) that all ideations take place from particular perspectives. This means that there are many possible conceptual schemes, or perspectives in which judgment of truth or value can be made. This is often taken to imply that no way of seeing the world can be taken as definitively "true", but does not necessarily entail that all perspectives are equally valid.
