“The bodily effect of our sufferings is less than one would suppose; it is memory that prolongs the pain, imagination which projects it into the future, and makes us really to be pitied. This is, I think, one of the reasons why we are more callous to the sufferings of animals than of men, although a fellow-feeling ought to make us identify ourselves equally with either. We scarcely pity the cart-horse in his shed, for we do not suppose that while he is eating his hay he is thinking of the blows he has received and the labors in store for him.” – Jean-Jacques Rousseau, Emile (quoted by Jacques Derrida in Of Grammatology (trans. Gayatri Chakravorty Spivak))
