And hard the conflict: horrible the thought,
That Love, who boasts of his all-conquering impulse,
Should have to mourn abortive energies...
But in proportion as Mankind increase,
So evils multiply: till Nature's self,
(The native passions of the human mind)
Engender War; which thins, and segregates,
And rectifies the balance of the world:
As thick-sown plants in the vegetable world,
With stretching branches wage continual War;
