[I]f we suppose, that to-morrow I will be changed to you, and you into I, there is no change at all, because then the you is the I, and the I the you… - Lewis Gompertz

The economy of life seems to be that man and most animals if in peace and plenty, would soon overstock the world with their produce, and that most species continue to increase till they exceed the food provided for their support, or till killed to make way for others. Some moralists admire this system of one animal devouring another as they say by this means more can live, and consequently they infer more happiness results. But that more can live by this means we doubt, and still more that the degree of happiness is increased; first, they must convince us that life generally abounds in pleasure, as to us the reverse seems to be the fact; though necessarily admitted by the Almighty for reasons beyond our reach to discover. If we look at the forest, the ocean, the air, or a drop of water in a microscope, all is found teeming with life, and to a superficial eye all is in active enjoyment; but a nice observer soon discovers the universal discord, trepitude and destruction proceeding everywhere: the strong oppressing the weak, one party half starved and ravenously pursuing another, some terrified devoted victims vainly endeavouring to escape the hungry jaws of their pursuer, some perished by want, others devoured alive, thousands destroyed every instant, and few allowed to remain, but those few so nicely balanced as to preserve the species through numerous ages; every fly or reptile, however contemptible in the eyes of some persons being possessed of a pedigree more remote than the most ancient nobility can emblazon, great grandfathers and mothers from time immemorial; and notwithstanding they are in the midst of their enemies, including man, who use every means and violence to destroy them; here by the care of God, they remain preserved from thousands of years back, as uninjured as if in a bandbox!!

It seems that most animals produce many more offspring than can find food, but that their numbers are kept small by other animals who prey upon them, otherwise they would perish by famine: which of the two evils would be the greatest we do not pretend to determine, but as the former is the plan most adopted we must believe it to be the best.

Such animals as be wants, he will nourish on the dregs and refuse of his own food, and give this as a gift; while those which are useless to him are left in a state of starvation, and deprived of the shelter of the forests, cut down by man.
