The philosopher and scientist Rene Descartes is known for his belief that animals are unfeeling machines, incapable of pain or emotion. To test his theory, it is said that Descartes nailed his wife's dog to a board and dissected it while it was still alive. This action, along with other acts of animal cruelty, has caused many to revise their opinion of Descartes. However, some claim that Descartes did not hold this view and that his conception of animals was more nuanced.

What You'll Learn
Descartes' beliefs about animals
The French philosopher René Descartes held the belief that animals are material automata without minds. He argued that animals lack language and general intelligence, and therefore do not have souls. This led him to conclude that animals are incapable of suffering and are simply machines.
Descartes' views on animals are closely linked to his theory of dualism, which asserts that the mind or soul is entirely distinct from the physical body. He believed that the soul resides in the pineal gland and gives consciousness. However, he argued that animals, lacking souls, are purely physical beings.
To test his theory, Descartes conducted vivisections on dogs, including his wife's dog. He nailed the dogs to boards, chopped them open, and mutilated them in various ways. When the animals reacted as if they were in pain, Descartes dismissed their cries as the mere sound of a machine functioning improperly. He maintained that a crying dog is no different from a whining gear that needs oil.
These cruel experiments have led to much criticism of Descartes, with some questioning his moral character and compassion. However, it is important to note that animal vivisection was commonplace among scientists in the Early Modern era, and Descartes' contributions to philosophy remain influential despite his controversial methods.
While Descartes' extreme beliefs about animals have been condemned, his broader philosophical contributions continue to be studied and debated. His ideas on dualism, the mind-body problem, and the nature of consciousness have had a significant impact on the field of philosophy.

Animal vivisection in the Early Modern era
Animal vivisection, or the act of conducting surgery on living organisms, typically animals with a central nervous system, was a common practice among scientists in the Early Modern era. The procedure was used to observe internal structures and functions that could not be seen in non-living subjects. While the practice has raised ethical concerns in recent times, it was a prevalent method in the Early Modern period, with notable figures such as Descartes, Vesalius, and William Harvey known for their involvement.
Descartes and Animal Vivisection
One of the most well-known figures associated with animal vivisection in the Early Modern era is René Descartes. Descartes, a French philosopher, is infamous for his belief that animals were incapable of suffering because they lacked a soul. To test this theory, Descartes conducted vivisection on animals, particularly dogs, which involved nailing them to boards and dissecting them while they were still alive. He dismissed the animals' reactions to pain as mere signs of a machine malfunctioning, stating that "a crying dog...is no different from a whining gear that needs oil."
Descartes' actions have been described as cruel and unnecessary, and they have caused controversy among those who study his philosophical theories. However, it is important to note that animal vivisection was a common practice among his peers as well, and the ethical standards regarding animal experimentation were different in the Early Modern era.
Animal Vivisection by Descartes' Peers
Animal vivisection was not exclusive to Descartes, and it was practiced by other scholars before him, such as Vesalius, who used it to investigate nerve function, lung action, and blood circulation. William Harvey, a peer of Descartes, also utilized animal vivisection, specifically the vivisection of dogs, in his investigations of blood circulation and valves.
The Emergence of Anti-Vivisection Movements
In the 19th century, as medicine underwent a transformation, the use of animal vivisection became a subject of moral debate. The emergence of organizations such as the RSPCA and the formation of anti-vivisection societies indicated a growing concern for animal welfare and rights. While some argued that animal experimentation was necessary for medical advancements, others believed that inflicting pain and injury on animals was inherently immoral, regardless of the potential benefits to humanity.
In conclusion, animal vivisection in the Early Modern era was a common practice among scientists and scholars, but it also sparked ethical debates and the emergence of anti-vivisection movements, particularly in the 19th century, as society began to question the moral implications of inflicting pain and suffering on animals.

Cartesian influence on vivisection
The Cartesian model, influenced by B.F. Skinner's behavioural psychology, has had a significant influence on vivisection. Vivisection, derived from the Latin words "vivus" (alive) and "sectio" (cutting), refers to surgery performed on living organisms, typically animals with a central nervous system, for experimental purposes.
Rene Descartes, a French philosopher, is known for his belief that animals were soulless machines incapable of feeling pain or suffering. To test this theory, Descartes conducted vivisection experiments, particularly on dogs, where he nailed them to boards and dissected them while still alive. These acts were justified by Descartes' belief that animals lacked souls and, therefore, could not truly suffer. This indifference towards animal welfare set a precedent for future vivisection practices.
The impact of Cartesian thought on vivisection sparked debates and moral questions. Literary figures such as Joseph Addison, Alexander Pope, and Samuel Johnson condemned vivisection as cruel. The emergence of the anti-vivisection movement in the 19th century, attracting supporters associated with women's suffrage, further challenged the practice. These critics argued that animals possess natural rights similar to humans and that inflicting pain or injury is inherently immoral, regardless of potential benefits.
While the direct influence of Descartes on vivisection practices has diminished, his philosophical legacy continues to shape societal attitudes towards animal ethics. Today, Cartesian, Kantian, and Darwinian perspectives on animal welfare coexist uneasily. While some scientists still espouse Cartesian views, dismissing animal suffering, others advocate for more moderate positions, recognising the need for ethical considerations in research.

Catholic Church's view on Descartes' work
The Catholic Church's view on Descartes' work is a complex topic, influenced by historical and philosophical factors. On the one hand, Descartes himself was a Catholic and explicitly declared his willingness to submit to the authority of the Catholic Church. In his writings, Descartes advanced the principles of the Holy Scriptures and Judeo-Christianity. For example, in his "Meditations," he makes a direct reference to Catholic instruction, demonstrating his advocacy for the contemplation of God.
Additionally, Descartes' theory of the dual nature of human beings—a material and mortal body united with an immaterial and immortal soul—is in concordance with Judeo-Christian beliefs. This conception remains a central part of Judeo-Christian doctrines, suggesting that Descartes' work aligns with Catholic teachings in this aspect.
However, it is important to note that during Descartes' time, the Church did not always accept new scientific ideas that intersected with religion graciously. The Church's treatment of Galileo and his heliocentric theory is a notable example of this tension. Descartes was conscious of this and proceeded cautiously with the development and justification of his theories, hoping to avoid any conflict with Catholic authorities.
Furthermore, there is evidence that Descartes' work on animal vivisection, specifically his dissection of dogs, has been a subject of controversy. While this practice was commonplace among early modern scientists and was not exclusive to Descartes, his alleged cruelty toward animals has caused some to question his ethics.
Despite these debates, it is worth mentioning that the Catholic Church never officially condemned Descartes' work, and he was not considered a heretic by the Church. Overall, the Catholic Church's view on Descartes' work is nuanced, reflecting the complex interplay between science, philosophy, and religion during his time.

Descartes' experiments on animals
The French philosopher Rene Descartes is known for his experiments on animals, particularly his wife's dog, to prove that animals do not feel pain and are merely unfeeling machines. He nailed the dog to a board and dissected it alive, dismissing its cries as the sound of a machine functioning improperly. This belief that animals were soulless and incapable of suffering led to further experiments where animals were burned, scalded, and mutilated.
Descartes' belief that animals were unfeeling machines was not unique to him, as animal vivisection was commonplace among early modern scientists. However, his influence on the increase in vivisection practices cannot be denied. The Cartesian view that animals were automata sparked controversy in early modern European philosophy, with some philosophers arguing that animals do feel pain and have sensations.
While Descartes' experiments on animals are disturbing, it is important to note that his contributions to science and philosophy are significant. He accepted and encouraged experimental work, conducting his own experiments on a wide range of subjects beyond just animal dissection. Descartes' impact on the advancement of knowledge cannot be overlooked, even if some of his methods were questionable.
In conclusion, Descartes' experiments on animals, particularly his wife's dog, were motivated by his belief that animals were unfeeling machines incapable of suffering. His actions, though disturbing, must be understood within the context of the scientific and philosophical beliefs of his time.
