Disquisitions relating to Matter and Spirit (1777) is a major work of metaphysics written by eighteenth-century British polymath Joseph Priestley and published by Joseph Johnson. [1]
Between 1774 and 1778, while he was serving as an assistant to Lord Shelburne, Priestley wrote five major metaphysical works, in which he outlined his materialist philosophy, even though such a position "entailed denial of free will and the soul." [2]
In the first of these works, The Examination of Dr. Reid's Inquiry. . . Dr. Beattie's Essay. . . and Dr. Oswald's Appeal (1774), [3] Priestley had strongly suggested that there was no mind-body duality. Such a position shocked and angered many of his readers who believed that such a duality was necessary for the soul to exist. In order to explain his belief more clearly Priestley wrote the Disquisitions, which claimed that both "matter" and "force" are active, and therefore that objects in the world and the mind must be made of the same substance. Moreover, he contended that discussing the soul was impossible because it is made of a divine substance, and humanity cannot access the divine. He therefore denied the materialism of the soul, while simultaneously claiming its existence. Although he buttressed his arguments with familiar scholarship and ancient authorities, including scripture, he was labeled an atheist and at least a dozen hostile refutations of the work were published by 1782.

Joseph Priestley was a British natural philosopher, Dissenting clergyman, political theorist, and theologian. While his achievements in all of these areas are renowned, he was also dedicated to improving education in Britain; he did this on an individual level and through his support of the Dissenting academies. His grammar textbook was innovative and highly influential. More importantly, though, Priestley introduced a liberal arts curriculum at Warrington Academy, arguing that a practical education would be more useful to students than a classical one. He was also the first to advocate the study and teaching of modern history, an interest driven by his belief that humanity was improving and could bring about Christ's Millennium.

Metaphysics is the branch of philosophy that investigates principles of reality transcending those of any particular science. Cosmology and ontology are traditional branches of metaphysics. It is concerned with explaining the fundamental nature of being and the world. Someone who studies metaphysics can be called either a "metaphysician" or a "metaphysicist".
