It has been generally, but not always, the custom of naturalists to degrade the powers of dumb animals into mere instinct, and not to allow them reason; and on the other hand to elevate the qualities of man, by entirely disavowing the power of instinct in man, giving him the use of reason alone. It appears to me, that there is such a quality as instinct; by which I understand a desire to do any thing without knowing why, or without having the object in view which it is to reach. I am of opinion that both reason and instinct act in man and also in brutes; and I will even grant that the proportion of reason to instinct is greater in man than in other animals; but that the latter possess a great portion of reason would it seems be absurd to dispute.
English philosopher, writer, inventor, and social reformer (1783/4–1861)
(1783/4 – 2 December 1861) was an English philosopher, writer, inventor, and social reformer. He was best known for his pioneering advocacy of the moral consideration of animals, early veganism, and opposition to animal exploitation. A founding member of the Society for the Prevention of Cruelty to Animals (later the RSPCA), he later established the Animals' Friend Society to promote a more comprehensive ethical stance toward animals. His 1824 treatise, Moral Inquiries on the Situation of Man and of Brutes, offered one of the first systematic critiques of animal use, combining philosophical argument with proposals for social reform. He also supported causes including women's rights, anti-slavery, and the welfare of the poor. In addition to his activism, Gompertz was an accomplished mechanical inventor who sought to develop alternatives to animal labour.
