I think one of the problems [with raising intelligent children in modern society] is compulsory schooling...and that children are sitting there, and they are taught and told what to believe; they are passive from the very beginning – and one must be very, very aggressive intellectually to have a high IQ [...] the child is taught. Right from the beginning, it's a passive process. He or she sits there, and they simply try to believe everything they're told?
