Richard Ithamar Aaron, was a Welsh philosopher who became an authority on the work of John Locke.
Early life and education
Born in Blaendulais, Glamorgan, Aaron was the son of a Welsh Baptist draper, William Aaron, and his wife, Margaret Griffith. He was educated at Ystalyfera Grammar School, followed by a spell at the University of Wales starting in 1918, where he studied history and philosophy. In 1923 he was elected a Fellow of the university, allowing him to attend Oriel College, Oxford, where he was awarded a DPhil in 1928 for a dissertation entitled "The History and Value of the Distinction between Intellect and Intuition".
Career
In 1926 Aaron was appointed a lecturer in the Department of Philosophy at Swansea University. After the retirement of W. Jenkin Jones in 1932, Aaron was appointed to the chair of philosophy at Aberystwyth University where he settled, initially on the nearby hill of Bryn Hir and later at Garth Celyn. Although his early publications focused on epistemology and the history of ideas, Aaron became fascinated with the work and life of John Locke. The interest was sparked by his discovery of unexamined information in the Lovelace Collection: a collection of notes and drafts left by John Locke to his cousin Peter King. There he found letters, notebooks, catalogues, and most pertinent of all, an early draft of Locke's "An Essay Concerning Human Understanding", hitherto presumed missing. Aaron's research led to the 1937 publication of a book covering the life and work of Locke, which subsequently became the accepted standard work on the subject. The proofs were read by Rhiannon Morgan, whom Aaron married in 1937. They had five children. Aaron produced several more books and articles, including a book in Welsh on the history of philosophy, Hanes athroniaeth—o Descartes i Hegel in 1932. He attempted to boost interest in philosophy in Wales, and established a philosophy section at the University of Wales Guild of Graduates in 1932, a society which still conducts all its proceedings in Welsh. Other notable publications of Aaron's include an essay, "Two Senses of the Word Universal" and "Our Knowledge of Universals", a study read to the British Academy in 1945 and published in volume 23 of its Proceedings. Aaron's work shows fascination with the idea of a Universal, which culminated in a 1952 book The Theory of Universals. Here he attacks the notion of universals as Platonic forms, but is equally critical of Aristotelian realism about essences, as he is of nominalism and conceptualism as theories of universals. In 1952–1953, Aaron was invited to be Visiting Professor at Yale University. In 1956 he was able to study the third draft of Locke's An Essay Concerning Human Understanding at the Pierpont Morgan Library, which resulted in a substantial addition to the second edition of John Locke, published in 1955. He was made a Fellow of the British Academy and President of the Mind Association in the same year. In 1956 an annual lecture hosted by the Aristotelian Society and the Mind Association was instituted in Aberystwyth, and Aaron was invited to give the inaugural lecture. In 1957 he was elected President of the Aristotelian Society. In 1967 Aaron published a second edition of The Theory of Universals, with a new preface and several additions and rewritten chapters. In 1971, he published a third edition of his Locke biography and the book Knowing and the Function of Reason, which includes a broad discussion of the laws of non-contradiction, excluded middle and identity, of the use of language in speech and thought, and of substance and causality. After retiring in 1969, he taught for a semester at Carlton College in Minnesota before returning to Wales, where he. helped write articles for the 1974 edition of the Encyclopædia Britannica. He began to feel the effects of Alzheimer's disease, and died at his home on 29 March 1987. Richard Aaron was the father of the academic and Welsh literature specialist Jane Aaron, born in 1951.
