However, he gradually came to question the divinity of Jesus, while accepting much else of Christianity-in the process becoming an early Unitarian. In 1752 Priestley decided to return to his theological studies and matriculated at Daventry, a Dissenting academy and spent most of his life employed as a preacher or teacher. Also, he was introduced to mathematics, natural philosophy, logic, and metaphysics through the works of Isaac Watts, Willem’s Gravesande, and John Locke. Later on, Priestley also studied languages including French, Italian, and German as well as Aramic and Arabic. Around 1749, Priestley became seriously ill and believed he was dying. Priestley’s illness left him with a permanent stutter and he gave up any thoughts of entering the ministry at that time. His thinking developed from Calvinism to Unitarianism.
Priestley was taught mostly at home and began studying theology and ancient languages at a nonconformist school in Daventry at the age of 19. His mother died in 1739 and the boy was adopted by his aunt, Sarah Keighley. Joseph Priestley was the son of a cloth maker and was born near the Oakwell Hall mansion, West Yorkshire, UK. Joseph Priestley, Experiments and Observations of Different Kinds of Air (1775) Joseph Priestley – Early Years “It is known to all persons who are conversant in experimental philosophy, that there are many little attentions and precautions necessary to be observed in the conducting of experiments, which cannot well be described in words, but which it is needless to describe, since practice will necessarily suggest them though, like all other arts in which the hands and fingers are made use of, it is only much practice that can enable a person to go through complex experiments, of this or any kind, with ease and readiness.” Being a rather prolific author with more than 150 works published, he is usually credited with the discovery of oxygen, having isolated it in its gaseous state, although Carl Wilhelm Scheele and Antoine Lavoisier also have a claim to the discovery.
