From whence comith this? Brings back memories from my collegiate days (mid 60's). I once ventured into a philosophy class, not by choice but by academic requirement and heard something similar.
You were probably in a logic class, something I think should be taught systematically from sixth grade on up (by private schools, not state schools). The philosophy department, while containing the most psychotic leftist nuts, also contains some of the most consistent conservative Christians.
The Marxists have used the American people’s utter lack of logic to pull the wool over our eyes. How else do we think Obama can think he can get away with blaming ATMs and corporate jet owners for the bad economy?
