 Alexander’s work was widely celebrated during his lifetime. J. H. Muirhead (1939: 3) wrote that, after Bradley’s death in 1924, Alexander was “the leading figure in British philosophy, and whom all schools, whatever their differences, were delighted to honour as their chief”. John Laird (1939: 61–5) described Space, Time, and Deity as “the boldest adventure in detailed speculative metaphysics” since Hobbes. Although he never founded a school of philosophy, Alexander is credited with having an influence on figures as diverse as new realists Laird, C. D. Broad, and Edwin B. Holt; the process philosopher A. N. Whitehead; John Anderson, “father of Australian philosophy”, and his school at Sydney; British idealists May Sinclair and Hilda Oakeley; and philosopher of history R. G. Collingwood. A number of studies were produced on Alexander’s work in the mid-twentieth century, but it then saw a period of neglect. Over the last decade or so, interest has increased, as indicated by Fisher’s (2021) collection Marking the Centenary of Samuel Alexander’s Space, Time and Deity.
