I don't know about you, but I definitely don't read enough philosophy (I don't read enough, period). Recently I was exposed to the philosophical view of perspectivism and it knocked my socks off. It feels like a conceptual cure for all that ails us, or at least a damn good dose of reality. A lot of this stuff you probably already "know," but I've found the clear conceptual framework of perspectivism easier to grasp and keep close at hand. Combined with ideas like non-violent communication, realizations like perspectivism provide the foundation for relating to one another in a more peaceful and understanding fashion, as well as with an efficiency that makes it more likely to actually find common ground on social problems and to perhaps even collaborate in solving them.
Here's what my cutting and pasting of wikipedia has to say about perspectivism (it might look like a slog, but trust me, it's worth it):
take place from particular perspectives. This means that there are many possible conceptual schemes, or perspectives which determine any possible judgment of truth or value that we may make; this implies that no way of seeing the world can be taken as definitively "true", but does not necessarily propose that all perspectives are equally valid.
Perspectivism rejects objective metaphysics as impossible, and claims that there are no objective evaluations which transcend cultural formations or subjective designations. This means that there are no objective facts, and that there can be no knowledge of a thing in itself. This separates truth from a particular (or single) vantage point, and means that there are no ethical or epistemological absolutes.  This leads to constant reassessment of rules (i.e., those of philosophy, the scientific method, etc.) according to the circumstances of individual perspectives. “Truth” is thus formalized as a whole that is created by integrating different vantage points together.
We always adopt perspectives by default, whether we are aware of it or not, and the individual concepts of existence are defined by the circumstances surrounding that individual. Truth is made by and for individuals and peoples.
The article includes a quote from Nietzsche's post-humous, The Will to Power:
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.[emphasis added] 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.
