We had a history teacher at school who never gave anyone more than 8 out of 10 for a piece of work, no matter how good. It made a mockery of the ten-point scale. Likewise in language, having words we're wary of using is a shame. I like "true" and use it a lot. Anyway, I know what's underlying this, of course, so let me say without fear or favour that evolution is real. It's a true phenomenon! We also have a theory for it which is very good at trying to get closer to the truths therein. That's what science is all about, trying to look for what is really true. Of course, there is one area of human thought that routinely misuses the word, We call it religion.
