The Main point Neil Postman is trying to get across is that students were never fully taught about what a definition really is. Neil says, “From the earliest grades through graduate school, students are given definitions and, with few exceptions, are not told whose definitions they are, for what purposes they were invented, and what alternative definitions might serve equally as well. The result is that students come to believe that definitions are not invented; that they are not even human creations; that, in fact, they are—how shall I say it?—part of the natural world, like clouds, trees, and stars.”
