One more current battle involving the unknown is between sociobiologists and antisociobiologists， and it is a marvel for students to behold. To observe， in open-mouthed astonishment， one group of highly intelligent， beautifully trained， knowledgeable， and imaginative scientists maintaining that all behavior， animal and human， is governed exclusively by genes， and another group of equally talented scientists asserting that all behaviors is set and determined by the environment or by culture， is an educational experience that no college student should be allowed to miss. The essential lesson to be learned has nothing to do with the relative validity of the facts underlying the argument. It is the argument itself that is the education： we do not yet know enough to settle such questions.
