Stace's first 4 books -
A Critical History of Greek Philosophy (1920),
The Philosophy of Hegel: A Systematic Exposition (1924),
The Meaning of Beauty (1929), and
The Theory of Knowledge and Existence (1932) - were all published while he was employed by the Ceylon Civil Service. After these early works, his philosophy followed the British empiricist tradition of
David Hume,
G.E. Moore,
Bertrand Russell and
H.H. Price. However, for Stace,
empiricism did not need to be confined to propositions which it is possible to demonstrate. Instead, our common sense beliefs find support in two empirical facts: (1) men's minds are similar (2) men co-operate with each other, with the aim of solving their common problems. Many scholars regard
Mysticism and Philosophy (1960) as his major work. Stace was the dissertation advisor of
John Rawls when Rawls was a graduate student at Princeton, though it is not clear that he had a strong influence on Rawls.
Richard Marius attributed his loss of faith partly to his intellectual engagement with Stace's essay
Man Against Darkness.
Phenomenalist philosophy His work in the 1930s and 40s bears a strong influence of
phenomenalism, a form of radical empiricism (not to be confused with
phenomenology, which examines the structure and content of consciousness). The book can be seen as a criticism of pragmatism. His paper
Refutation of Realism (1934) acted as a response to G.E. Moore's famous refutation of idealism. Stace did not argue that realism is false, but that "there is absolutely no reason for asserting" it is true, so it "ought not be believed". Turning from epistemology to ethics, in 1937 he considered whether morals were relative or subject to a general law in
The Concept of Morals.
The public philosopher In 1948, Stace wrote an influential essay,
Man Against Darkness, for
The Atlantic Review in which he examined religion. He concluded that the spirit of scientific enquiry (rather than scientific discoveries themselves) has furthered religious scepticism by undermining the
teleological presumption of an ultimate '
final cause'. Concern with divine purpose of events had been replaced by investigation into what had caused them; the new imaginative picture of the world was dominated by the idea that life is purposeless and meaningless. The effects of this change included moral relativity, the individualisation of morality, and the loss of belief in free will. Stace wrote: In the spring of 1949, the
Massachusetts Institute of Technology hosted a forum called "The Social Implications of Scientific Progress—an Appraisal at Mid-Century."
Winston Churchill,
Harry S. Truman,
Vannevar Bush,
Nelson Rockefeller were amongst those in attendance. Stace took part in a discussion called 'Science, Materialism and the Human Spirit' alongside
J. Seelye Bixler (1894-1985),
Percy W. Bridgman and
Jacques Maritain. He contributed an essay,
The Need for a Secular Ethic, in which he concluded that although supernatural or metaphysical justifications for morality are in decline, this should not lead to a crisis of the moral faith if it is remembered that 'morals have a perfectly firm and objective foundation in the human personality'. In 1954, he gave the annual
Howison Lecture in Philosophy at
University of California, Berkeley, where he spoke on "Mysticism and Human Reason". In the fall of 1957, two years after retiring from his post at Princeton, Stace was involved in a controversy surrounding Dr. Joseph Hugh Halton (1913-1979), a member of the Roman Catholic Dominican Order (Order of Preachers) who was the Roman Catholic chaplain at Princeton University and the Director of the Aquinas Institute (located near the Princeton University campus). Halton criticised the university's 'abusive liberalism', and Stace was the first of those singled out for censure. Halton stated that 'Stace is enthroning the devil' and that he was 'professionally incompetent', while his philosophy was described as a 'metaphysical mambo'. The Princeton president
Dr. Robert F. Goheen stripped Dr. Halton of his title, an action which was supported by Jacques Maritain, the noted Roman Catholic philosopher and theologian and former Princeton professor. Stace continued to engage with the public until the end of his career. Two of his final books,
Religion and the Modern Mind (1952) and
The Teachings of the Mystics (1960) were written for the general reader. He gave lectures at various university campuses around the United States, many of which were included in
Man Against Darkness and other essays (1967). ==Philosophy of religion and mysticism==
