I definitely agree to such a course. Usually it was covered in such courses as Literature and Political Science. It would be interesting to locate texts for such a course.

From what I've seen, the "new" education automatically includes such thinking. Another poster on this forum complained about a math problem where questions were asked based on an illustration (or diagram) that the answers could be answered "considering 20 initial items." He complained that in the first diagram there were only 19 items. I don't know why, but this confused him because his thinking was so limited. I don't believe this was a printing error. The only honest answer would be that "solutions could not be found based on the diagram." All that was necessary was to recognize that the first diagram contained one less than was stated. Anyone who expects to answer an unsolvable problem is the bearer of constricted thinking. He also could have responded on the assumption that there actually were 20 items. But his answers would require that this be stated initially. (No imagination.)

Y'know Glaucon, lately I've been thinking about the difference between really stupid and merely ignorant. Stupidity, of course, is permanent, and may result from genetic inheritance or some sort of brain damage. Ignorance, on the other hand, is curable. Judging textual construction and spelling, several posters on this forum aren't stupid, but surprisingly ignorant.

Wouldn't it be great if every grammar and high school in the country had courses on critical thinking? FOX News would rail against such a plan of course - it would slowly put them out of business! What a delightful idea!!
