This question arose in a previous HN post "Set Theory and Foundations of Mathematics" https://news.ycombinator.com/item?id=9981229 .
Meanings aren't found, because they aren't an aspect of the outside world but of our mental landscape. Meanings are invented by human beings and then imposed upon the outside world. As a result, I'm sure some people have already imposed a meaning upon everything in their mental landscape, while others have not. It helps if you limit your mental landscape to only those things to which you can readily impose a meaning you find convenient and desirable, and ignore the rest of the outside world.
