Joseph priestley biography pdf

Together, the two volumes will stand as the standard biography of Priestley for years to come. Joseph Priestley —a contemporary and friend of Benjamin Franklin and Thomas Jefferson, exceeded even these polymaths in the breadth of his curiosity and learning. Yet Priestley is often portrayed in negative terms, as a restless intellect, incapable of confining himself to any single task, without force or originality, and marked by hasty and superficial thought.

In fact, he was learned in an extraordinary variety of subjects, from grammar, education, aesthetics, metaphysics, politics, and theology to natural philosophy. Priestley was, in fact, a man of the Enlightenment. The first volume, published incovered the first forty years of Joseph Priestley's life in England. In this second volume, Schofield surveys the mature years of Priestley, including the achievements that were to make him famous -- the discovery of oxygen, the defenses of Unitarianism, and the political liberalism that characterized his later life.

He also recounts Priestley's flight to Pennsylvania in and the final years of his life spent along the Susquehanna in Northumberland. Joseph Priestleya contemporary and friend of Benjamin Franklin and Thomas Jefferson, exceeded even these polymaths in the breadth of his curiosity and learning. In The Englightened Joseph Priestley, he emerges as a man who was more than a lucky empiricist in science, more than a naive political liberal, more than an exhaustive compiler of superficial evidence in militant support of Unitarianism.

His mother died when Joseph was still young, and he went to live with a childless aunt, Sarah Keighley, herself staunchly Calvinist, whose home was nevertheless a center for Dissenting ministers of all persuasions.

Priestley found to his dismay that he lacked any such experience but he continued to consider himself a good Christian, which caused a rift with his aunt and his family and with his local parish.

Unorthodoxy and controversy were his vocations; after an Arminian and an Arian period, he became eventually the chief exponent of Unitarianism in Britain. A deep intellectual and personal belief in divine Providence sustained him throughout; there is no sign that he was simply an intellectual in incomplete transit to deism, pantheism or agnosticism.

After six difficult years as an unknown Dissenting clergyman and school teacher, in Priestley was offered the position of tutor in languages and literature at Warrington Academy. There he lectured on modern history, rhetoric, literary criticism and aesthetics. He first made his name as an author with three works: a textbook on English grammar, a study of the theory of language, and an essay on the aims and practice of education.

At Warrington he found time to start a new career as an historian of science, beginning with a well-received history of discoveries in electricity, for which he conducted many experiments of his own. It also set him on the path towards his brilliant experimental career. In this period he wrote his most substantial political work, the Essay on the First Principles of Government ofwhich is also his first philosophical essay.

There are no natural political rights, however. Political rights vary in place and time. No one form of government — from absolute monarchy to radical democracy — is naturally better than any other. Good government is not a matter of form but of the moderation of the rulers, of uniform laws, and of respect for civil liberties. His later radicalism arose not from any marked philosophical change but from coming to think the British government immoderate and intrusive.

In Priestley was employed as the librarian and companion of Lord Shelburne, with much free time to pursue his scientific and joseph priestley biography pdf writings. It was in this period that he entered into the metaphysical disputes of his day. He sees nature as everywhere exhibiting order, and yet as not in any way self-ordering, since nothing we see in nature shows order arising naturally.

He reinforces this position with an appeal to the Cosmological Argument. Nothing in the Institutes suggested the controversies that were soon to follow. English philosophy had long been dominated by dualism. He admired Hobbes, but did not borrow from him. Reid believed that Berkeley and Hume had destroyed the claim that ideas represent reality by showing that our sensations do not in fact resemble the qualities of external objects.

For him ideas are not images, and the Theory of Ideas is not a theory of pictures in the brain. The Theory, he thinks, requires only that objects and ideas stand to each other as cause to effect. Priestley seized upon it as showing Reid to be an occasionalist or unwitting idealist. It follows that ideas and objects must be of the same substance.

Following this logic, Priestley had no alternative but to declare himself a materialist. Underlying this debate is an issue about causal relations. Priestley agreed with Hume that causal relations contain regularities between events, but he denied that they are merely regularities. His rejection of interactionist dualism stems from its admitted inability to supply such a mechanism for interaction.

Newtonian dualists such as Price, Reid and Andrew Baxter had urged that matter and mind are irreconcilable because one is intrinsically passive and the other intrinsically active.

But, Priestley asks, if matter is wholly powerless, then what use is it, and why suppose it to exist at all? He follows John Michell a fellow scientist-clergyman in likening the Newtonian theory of matter and force to a structure of material bricks and immaterial mortar in which the mortar is doing all the work. Priestley and Michell were themselves indebted to the Jesuit scientist Roger Joseph Boscovich, whom they had both met.

Closer scrutiny reveals some differences between Boscovich and Priestley. Priestley wholly accepted his insistence on the powerfulness of matter.

Boscovich had reached this conclusion by arguing that the Newtonian account of mechanical impulse required finite velocities to be lost and gained in a single instant of time, thus violating the Leibnizian Law of Continuity. This argument is never mentioned by Priestley. Rather, the phenomena show us clear instances of the action-at-a-distance of forces, and nothing that cannot be readily explained by forces.
