Y: Do you bear in mind, that in breeding the silkworms, we cause more to come into existence than would otherwise be the case? Z: Though I think we a… - Lewis Gompertz

It is an axiom that the more pleasure and the less pain there is in the Universe, the better it is. If, then, a person suffer pain instead of pleasure, whether he be criminal or not, the pain will be increased and the pleasure decreased; and, as this disagrees with the axiom just cited, it is wrong.

And though I cannot conceive how any person can shut his eyes to the general state of misery throughout the universe, I still think that it is for a wise purpose; that the evils of life, which could not properly be otherwise, will in the course of time be rectified, and the exquisite pleasures for which we are formed will be enjoyed in our progeny: also that we may ourselves become the inhabitants of the improved world, or of some other world improved in a like manner; and that even if the different species of all the present animals should become extinct, as indicated by what we have observed of the different bones in the several strata, the discoveries of the present time may enrich the future, unless every trace of them should be destroyed at once.

Delightful representations of animated nature have indeed been made by the best authors, which I hope I shall be pardoned in dissenting from, and confess that though I am not blind to there being much enjoyment, the different evils of all animals, and of all classes of mankind, strike me with the most force. Those authors construe almost all things into so many tokens of happiness. If they look at a drop of water through a microscope, and see a multitude of animalcula swimming about, they seem to conclude that they must all be in a state of pleasure; not judging by analogy, that for one whose motions are the effect of happy sensation, there may be several which are struggling for food, from disease, and other such causes; that even the very fluid they inhabit is disputed by larger animals, who are continually destroying them and giving them the agonies of death after a very short life, whether it be of pleasure or of pain, and thereby embittering the draught of the thinking part of mankind. The different actions and cries indeed of all creatures, are adverted to as enlivening scenes of happiness; not noticing how many of them, which to the uninformed may appear to proceed from enjoyment, are in fact produced by fear, anger, pain, and the like; and which close observation will frequently discover them to be. How are the weak and sickly males oppressed by the strong and healthy ones, crossed in their amours, deprived of their food, injured in their bodies, and at last driven to end their lives in solitary places!
