One of the books I use in teaching is a nice little one about clear thinking by Jamie Whyte. I don't agree with all his arguments but it has great tools for crap detecting. One of his best lines is that you know that a political statement is meaningless when it would be impossible for a sane person to disagree with it: "this country needs hope" - "no it doesn't, it needs despair"; "we want a better health service" - "rubbish! I want a worse one." You get the idea.
Amongst the mountains of verbiage produced by the American Presidential candidates, unless I have dozed off and missed something, I haven't caught a single statement of substance. It all seems to follow Whyte's formula for saying nothing. Is this all there is or am I not listening hard enough?
