“The most interesting thing in nature is that two species exist, only two species, which are expansionist: mankind and insects. All other species are territorial. The insect is a devourer, an expander, it keeps on expanding so much and it doesn’t even care. And mankind is like that, as well… The two species which are going to end up fighting over the world are going to be insects and human beings.”
Lo que más interesante es en la naturaleza existen dos especies, unicamente dos especies que son expansionistas: el hombre y los insectos. Las demás especies son territoriales. El insecto es devorador, expansionista, hasta que se siegue expandiendo y no le importa. Y el hombre es así... las dos especies que van a acabar peleándose por el mundo van a ser insectos y hombres.

Essay on the Immortality of the Soul
Context: Heaven and Hell suppose two distinct species of men, the good and the bad; but the greatest part of mankind float betwixt vice and virtue. -- Were one to go round the world with an intention of giving a good supper to the righteous, and a sound drubbing to the wicked, he would frequently be embarrassed in his choice, and would find that the merits and the demerits of most men and women scarcely amount to the value of either.
