Viewing the world in absolutes is a pretty common way to learn nothing about it and reality as a whole. Many of our concepts especially the ones that are hard to verify have shifted a whole lot from their original usages exactly because many of our imaginary "perfect" concepts are simply not really applicable to reality. But before throwing a useful concept of idea away, one should try to modify it in a way that it would actually have meaning and a level of utility. Our concepts about the world should help us expand our knowledge or it instead of limiting it.

It's also import to mention the words are not magic and don't have permanently affixed meanings, but only usages with definitions that often differ depending on the contexts. That's why subscribing to the black and white understanding of a concept that is disconnected from reality is a way of actually misusing or at least underutilizing the power and/or utility of a particular concept. When we further our knowledge and/or understanding of a concept, we also develop the ability to refine its definition and usage instead of throwing it all away in an all-or-nothing scenario instead of just fixing what we have found to be contradictory or of lower practical value.
