" Moralists try to persuade us that the sexual instinct hasn't got so very much to do with love. They're apt to speak of it as if it were an epiphenomenon" .

“道德家试图说服我们， 性本能与爱并没有太大关系。他们倾向于把它当作一种附带现来谈论它” 。

Consequently, theories of evolution which consider the mind as emerging from the forces of living matter or as a mere epiphenomenon of this matter are incompatible to the truth about man.

因此，进化论认为心灵是从命物质力量中产，者仅仅是命物质附带现，与人类真相是不相容。
