““Thus we can regard the phenomenon of reproduction as founded in the very nature of being. But we must stop there. The perpetuation of the species does not necessitate sexual differentiation. True enough, this differentiation is characteristic of existents to such an extent that it belongs in any realistic definition of existence. But it nevertheless remains true that both a mind without a body and an immortal man are strictly inconceivable, whereas we can imagine a parthenogenetic or hermaphroditic society.””
