“It follows that physical love is a safety valve. If the present generation has not attained its aim, it has not done so because of its passions, of which the sex passion is the strongest. And if the sex passion endures there will be a new generation and consequently the possibility of attaining the aim in the next generation. If the next one does not attain it, then the next after that may, and so on, till the aim is attained, the prophecies fulfilled, and mankind attains unity. If not, what would result? If one admits that God created men for the attainment of a certain aim, and created them mortal but sexless, or created them immortal, what would be the result? Why, if they were mortal but without the sex passion, and died without attaining the aim, God would have had to create new people to attain his aim. If they were immortal, let us grant that (though it would be more difficult for the same people to correct their mistakes and approach perfection than for those of another generation) they might attain that aim after many thousands of years, but then what use would they be afterwards? What could be done with them? It is best as it is.⁠ ⁠… But perhaps you don’t like that way of putting it? Perhaps you are an evolutionist? It comes to the same thing.
