Opposites like BLUNT and SHARP delineate spectrums of metal hardiness, object shape, and/or communication expression styles between people amongst other descriptions. These words give us the tools to accurately describe so much of human existence through the prism of human experience; never-ending conflict. As long as there are moments, situations, and people, there will always be some sort of conflict. This is obviously an oversimplification. Hell, this book is one giant oversimplification, but a truth is a truth, no matter how overly simplified it is.
