He did not speak and his movements were chaotic. According to the philosopher François Dagognet, 'he walks on four legs, eats plants, is hairy, deaf and mute.' He was sent to an orphanage at Saint-Affrique three days later, then to another at Rodez on the 4 February. The psychiatrist Philippe Pinel, doctor at the Bicêtre Hospital, wrote a report on Victor and considered him to be mentally ill and an idiot from birth. Study Shortly after Victor was found, a local abbot and biology professor, Pierre Joseph Bonnaterre, examined him. He removed the boy's clothing and led him outside into the snow, where, far from being upset, Victor began to frolic about in the nude, showing Bonnaterre that he was clearly accustomed to exposure and cold. The local government commissioner, Constans-Saint-Esteve, also observed the boy and wrote there was "something extraordinary in his behavior, which makes him seem close to the state of wild animals". The boy was eventually taken to Rodez, where two men traveled each seeking to discover whether or not he was their missing son. Both men had lost their sons during the French Revolution, but neither claimed the boy as his son. There were other rumors regarding the boy's origins. For example, one rumor insisted the boy was the illegitimate son of a notaire abandoned at a young age because he was mute. Itard believed Victor had "lived in an absolute solitude from his fourth or fifth almost to his twelfth year, which is the age he may have been when he was taken in the Caune woods." That means he presumably lived for seven years in the wilderness. It was clear that Victor could hear, but he was taken to the National Institute of the Deaf in Paris for the purpose of being studied by the renowned Roch-Ambroise Cucurron Sicard. Sicard and other members of the Society of Observers of Man believed that by studying, as well as educating the boy, they would gain the proof they needed for the recently popularized empiricist theory of knowledge. In the context of the Enlightenment, when many were debating what exactly distinguished human from animal, one of the most significant factors was the ability to learn language. By studying the boy, they would also be able to explain the relationship between humans and society. Influence of the Enlightenment The Enlightenment caused many thinkers, including naturalists and philosophers, to
