It was the classics of Marxism that revealed those errors and pointed them out." - Trofim Lysenko (died 20 Nov 1976) "What mankind needs, declared everready Anthropologist Earnest A. Hooton, is 'a science . . . that will teach each person . . . how to behave like a human being.' He found cause for worry in an educational system that 'offers the student opportunities to learn about practically everything except himself.'" - quotes attributed to Earnest A. Hooton from Time magazine, 26 May 1947. | |
