In the old lingo, one’s ‘mind’ mediates one’s knowledge of anything.
And it seems all too easy for people to treat their ‘minds’ like ‘windows’ which they look through but never see.
It may not be so easy to get people to see the ‘window’ and to see, among other things, the obscuring, distorting ‘dirt’—some of it language-related—that they've gotten used to ignoring.
First, you have to look at your own ‘dirty window'— hard work even for the most intelligent.
