You may have heard that “common sense” is the most abundant resource in the Universe. After all, have you ever met anyone who thought they needed more?
I have met many, perhaps all of us, who think everyone else needs more. But, along that line, I may be deficient. Please explain to me how Romney endorsing Perry two years ago is more a positive for Romney that it is for Perry. I am missing the "pure" logic leading to that conclusion.
Concerning your personal page, I recommend to you James Burke's Connections. You may modify your opinion of human development. It is his opinion that the development of irrigation led to the development of agriculture which in turn led to counting, distribution, accounting, etc. It is a very interesting book.
