Signature………………………………………………………. 3 University of Sussex Elizabeth Sarah Kingston ‘The Language of the Naked Facts’ Joseph Priestley on language and revealed religion Summary Joseph Priestley (1733-1804) is usually remembered for his experiments in natural philosophy and celebrated for his isolation of the gas we now call oxygen. However, Priestley had a wide range of interests and published extensively on education, history, politics, political philosophy, language, theology and religion. He dedicated his life to elucidating a coherent set of epistemological, metaphysical and theological principles which he believed explained the human mind, the natural world and the nature of God and revelation. Recent studies of Priestley have emphasised the difficulties that arise from isolating the various aspects of his thought and the fruitful outcome of uncovering the many connections between his diverse areas of study. With this in mind, the present dissertation aims to elucidate the relationship between two aspects of Priestley’s thought that have not previously been studied together. It examines his theory of language and argument alongside his work on theology and the evidences of revelation. Chapter One provides an overview of Priestley’s epistemology, focusing on his work on induction, judgment and assent. Chapter Two looks at Priestley’s analysis of the role of the passions in our assent to propositions and the progressive generation of the personality, while paying particular attention to the origins of figurative language. Chapter Three examines Priestley’s theory of language development including the relationship between figurative language and the extension of vocabulary and the close connection between language and culture. Chapter Four demonstrates that Priestley’s discussion of the evidences of revealed religion is structured around his theory of assent and judgment. It also explains how assent to revelation is essential for the generation and transcendence of the ‘self’. Chapter Five brings all the themes of the dissertation together in a discussion of Priestley’s rational theology and examines his analysis of figurative language in scripture. 4 Dedication For my Grandparents 5 Acknowledgments The Arts and Humanities Research Council provided the funding that enabled me to carry out this work.

His work is testament to a fundamental need to identify regularity in the perceived chaos of existence and is evidence of a mind driven to classify the raw materials of experience. ‘The great business of philosophy’, he tells us, ‘is to reduce into classes the various appearances which nature presents to our view’. Priestley dedicated his life to elucidating a coherent set of epistemological, metaphysical and theological principles which he believed explained the human mind, the natural world, and the nature of God and revelation. Committed to the Newtonian methods of his era, Priestley rejected all conclusions based on speculation and insisted that his ideas were grounded only in reason and experience. According to Priestley the harmonious and interrelated principles that he identified were the inevitable result of careful observation and the formulation of propositions based on the induction of general laws from particular facts. Nature presents to our view particular effects, in connexion with their separate causes, by which we are often puzzled, till philosophy steps in to our assistance, pointing out similarity in these effects, and the probability of such similar effects arising from the same cause. For Priestley this process of induction is the very essence of reason: it is the method by which ‘we are obliged to proceed in our investigation of truth’. Priestley was attracted to the notion of pre-ordained uniformity in nature and envisaged an ordered universe governed by a set of simple laws, or chains of cause and effect, maintained by God. Immersed in limitless particularity and diversity of effects, the human mind is designed by a benevolent creator to comprehend overarching laws and identify common causes by a process of abstraction. Reason is a gift from God, it is the faculty that distinguishes us from animals and the means by which all ‘proper happiness’ and knowledge is attained. According to Priestley, a mind guided solely by reason will mechanically formulate universal propositions that reflect the objective order of external reality. Furthermore, Priestley believed his careful application of reason and his rigorous exclusion of passion, prejudice and irrationality from the process of logical 9 investigation had enabled him to access profound and universal truths. He devoted around two hundred publications to conveying these ideas in great depth and detail. 1 This commitment to reason and the inductive method tied together Priestley’s impressively wide range of intellectual pursuits. He published extensively on theology and religion, natural philosophy, metaphysics, history, education, oratory, politics, and political philosophy, and he is appreciated today for what John McEvoy calls the ‘synoptic unity’ of his thought. The systematic and coherent nature of Priestley’s mind allowed him to articulate a harmonious set of intellectual principles and explore the relationships between them with great clarity. A brief overview of his materialist, associationist and necessitarian outlook demonstrates the breadth of his philosophy. i) Materialism. Priestley posited that matter, rather than being impenetrable and inert, is subject to internal forces such as attraction and compulsion. This enabled him to argue that the matter of the brain is sensitive to vibrations that are the basis of all thought and to deny the existence of an immaterial soul. ii) Association of ideas. Priestley held that the vibrations that constitute thought are caused by external objects and he concluded that the mind has no innate ideas. Our ideas and mental states are acquired solely through sensory experience, and simple ideas are combined into complex ones by virtue of repeated conjunction or association. iii) Philosophical necessity. A wholly material mind is subject to the same causal laws as the natural world,
