In my personal experience, truth never lies at the extremes, only ever in the middle. Here's a bad example: It's never true that person X is a "horrible person" but rather that person X is horrible in some ways, wonderful in others, or horrible to some people, wonderful to others, or horrible at some times, wonderful at others, etc
It's a bad example because whether there is such a thing as "a horrible person" in the first place, is debatable. But bad or not, the example does illustrate the principle that more things are seen in shades of grey, than in pure black and white.
The ancient Greek philosopher Aristotle is among those hair-splitters who came up with the so-called Law of the Excluded Middle (who made it a law?), which crudely stated means that for any statement, either the statement is true or its opposite is true. In turn the Law implies that if something is true, its opposite is false; and if something is false, its opposite is true. The Law does not acknowledge any middle ground, but rather sees only the opposing extremes. (Which kind of describes the state of human culture today!).
The Law of the Excluded Middle is well-suited to Newtonian, deterministic, reductionist physics. In contrast, modern (Quantum/Einsteinian) physics deals mainly with probabilities, not unbreakable laws. And then there's quantum physicist Niels Bohr's "complementarity principle" in terms of which apparently contradictory things may both be true (eg light comes in waves; light comes in particles) depending on context, perspective and intention.
Just as Euclidean geometry has come to be recognised as one of many domains in a meta-geometry, so too is the Law's black and white logic just a small territory within a broader, meta-logic.
The above in relation to a FaceBook comment by James Quirk:
... the law of the excluded middle. And I think it's basically a false law. When we exclude the middle, we exclude everything that actually matters. As we all know, in the real world, life is never only A or only B. Aristotle's bifurcated logic disconnects itself from the ambiguity of reality, and lays the foundation for the creation of falsely-based cultures (like our current one). Even computers do not operate on strictly Aristotelian dualistic logic. There are three possible states for each circuit - on, off, and null. The null state is where "on" or "off" are meaningless because there is no power to the device at all.
