Scope and Content

The papers fall into three categories. The early series comprise a comprehensive record of David Armstrong's philosophical writings extending from his undergraduate days at the University of Sydney until the early 1980s. They include not only the drafts, usually handwritten, of his essays, articles, lectures and book reviews, but associated correspondence with other philosophers and with editors of journals, reviews of his early books, and his notes of lectures that he attended at Sydney and Oxford University.

Secondly, there is a series of files documenting Armstrong's strong interest in a range of social and political questions, especially during the Vietnam War years. They include speeches and addresses, articles for university and other newspapers, records of the Sydney University Association for Cultural Freedom, and papers on the 1970 and 1971 Vietnam Moratoriums.

The third category comprise papers relating to disputes within the Department of Philosophy at Sydney University and the split into two departments in 1973. They include correspondence, submissions, petitions, circulars, agenda papers, cuttings and other papers dating from 1965 until 1985.

Among the correspondents are John Burnheim, Keith Campbell, Noam Chomsky, Michael Devitt, Owen Harries, Eugene Kamenka, W.M. O'Neil, J.J.C. Smart and Alan Stout.


The papers were filed chronologically by Professor Armstrong in a number of series and this arrangement has been maintained by the Library.


The collection is available for reference.


The papers were donated by Professor Armstrong to the National Library under the Taxation Incentives for the Arts Scheme in 1992.

Biographical Note

David Malet Armstrong was born in Melbourne on 8 July 1926, the son of Commodore John Armstrong, RAN and Philippa Armstrong. He was educated at Dragon School, Oxford, and Geelong Grammar School. He served in the Royal Australian Navy in 1945-46. He then enrolled at the University of Sydney, where he graduated with an Honours degree in Philosophy in 1950. He continued his philosophical studies at Exeter College, Oxford, where his supervisor was H.H. Price. Graduating as a B.Phil., he lectured at London University before returning to Australia in 1955.

Armstrong took up a post as a Lecturer in Philosophy at the University of Melbourne in 1956, becoming Senior Lecturer in 1961. He was awarded a doctorate in 1960. In 1964 he returned to the University of Sydney as the Challis Professor of Philosophy and held this position until his retirement in 1991. Following a split in the Department of Philosophy in 1973, he was the first Head of the Department of Traditional and Modern Philosophy. Since 1991 he has been Emeritus Professor of Philosophy.

Armstrong's particular interests have been in the areas of the theory of knowledge and perception, the philosophy of mind and metaphysics and his writings quickly brought him an international reputation. He has held Visiting Professorships at Yale University, Stanford University and the Universities of Wisconsin, Texas and California. His principal publications are Berkeley's theory of vision (1960), Perception and the physical world (1961), Bodily sensations (1962), A materialist theory of the mind (1968), Belief, truth and knowledge (1973), Universals and scientific realism (1978), The nature of mind and other essays (1980), What is a law of nature? (1983), Consciousness and causality (1984), Universals (1989), A combinatorial theory of possibility (1989), A world of states of affairs (1997) and The mind-body problem (1999).

Armstrong is a Foundation Fellow of the Australian Academy of the Humanities. He was made an Officer of the Order of Australia (AO) in 1993.

Armstrong married Madeleine Haydon in 1950 and Jennifer Clark in 1982.

Series 6 Sydney University School of Philosophy, 1965-1985

Armstrong was appointed Challis Professor of Philosophy at Sydney University in 1964. In the following year he was a central figure in a public dispute when the Professorial Board overruled the decision of a Selection Committee to appoint Frank Knopfelmacher as a Senior Lecturer in the Department of Philosophy. Divisions within the Department became acute in 1971-1973. The issues included the introduction of a Marxist-Leninist course in 1971, the appointment of Patrick Flanagan as a tutor in 1972, an attack on Armstrong by his colleague Michael Devitt in a private note which led to debates and questions in the State Parliament, and moves to introduce a feminist course in 1973. These disputes culminated in a staff and student strike and demonstrations in June 1973. Faced with the possibility of an exodus of philosophers, the Vice-Chancellor decided in October 1973 to split the Department into two units: the Department of Traditional and Modern Philosophy initially headed by Armstrong and the Department of General Philosophy initially headed by John Burnheim. Together they constituted the School of Philosophy.

Armstrong assembled and retained a comprehensive collection of papers and printed material documenting these disputes in great detail (folders 1-21). They include correspondence, both private and official, open letters, statements, submissions, petitions, draft motions, agenda papers, circulars, leaflets, student newspapers and other publications, issues of journals and parliamentary debates. The correspondence includes letters from members of the public commenting on the disputes. The papers were kept in manila folders or loose in box letter files under the headings 'Knopfelmacher dispute', 'Marxist-Leninist dispute' and 'Philosophy disputes' and this general arrangement has been retained by the Library.

The 1974-1984 papers in this series (folders 22-37) mostly deal with the relations between the two departments following the 1973 split. They refer to such matters as proposals for common courses and seminars, the appointment of tutors and other staff, the staff-student ratios in the two departments, decision-making within the departments, the 1977 report on problems in the School of Philosophy, transfer of staff between the departments, discussions about curriculum, the role of Armstrong as the only full Professor in the School, and arguments about possible amalgamation of the departments in the early 1980s. They include copies of letters and other documents supplied to Armstrong by his colleagues in the Department of Traditional and Modern Philosophy.

The correspondents include John Burnheim, Keith Campbell, Paul Crittenden, Michael Devitt, John Gunn, Owen Harries, R. Ian Jack, Frank Knopfelmacher, Professor Henry Mayer, Graham Nerlich, Professor W.M. O'Neil, Professor H.L. Rogers, Professor R.N. Spann, Professor Edward Shils, David Stove, Professor Alan Stout, Professor J.M. Ward and Professor Bruce Williams.

Series 7 Miscellaneous papers, 1966-1976

The files in this small series were among the philosophical papers, but have been segregated as they deal with more general matters.

The first file documents Armstrong's involvement in the selection of the first Professor of Philosophy at the University of Tasmania since the dismissal of Sydney Sparkes Orr in 1956. The three files on overseas trips mostly consist of correspondence, both official and personal. The file on Armstrong's 1969 visit to England includes a large number of letters from his parents and friends and colleagues in Australia, some of them reporting on activities within the Department of Philosophy at Sydney University.

The correspondents include Tom Fitzgerald, Richard Krygier, Graham Nerlich, H.B. Acton (Edinburgh), John Beloff (Edinburgh), Peter Caldwell (Cambridge), Antony Flew (Keele), E.J. Furlong (Belfast), Selwyn Grave (Perth), Michael Hodges, D.A. Kearney (Hobart), (Nashville), James Moulder (Grahamstown), Stephen Pepper (Berkeley), Edward Poznanski (Jerusalem) and Roland Puccetti (Singapore).
