    Fatalism and the Omnitemporality of Truth.Richard L. Purtill - 1988 - Faith and Philosophy 5 (2):185-192.
    In this paper I will show that the omnitemporality of truth does indeed imply fatalism if the past is unchangeable. I then argue that it is very likely indeed that the past is unchangeable and thus, since it is very likely that fatalism is false, it is very likely that the doctrine of the omnitemporality of truth is false. I argue that the rejection of the omnitemporality of truth has no undesirable consequences for either logic or theology, that in fact (...)

  10. Proofs of Miracles and Miracles as Proofs.Richard L. Purtill - 1976 - Christian Scholar’s Review 6.
    AS AGAINST HUME’S VIEW THAT "A MIRACLE CAN NEVER BE PROVED SO AS TO BE THE FOUNDATION OF A SYSTEM OF RELIGION" I ARGUE THAT THE POSSIBILITY OF MIRACLES CAN BE DEFENDED ON PHILOSOPHICAL GROUNDS, THAT THERE IS HISTORICAL EVIDENCE FOR THE OCCURRENCE OF CERTAIN MIRACLES AND THAT SUCH MIRACLES CAN IN FACT GIVE GROUNDS FOR THE PREFERENCE OF ONE SYSTEM OF RELIGIOUS BELIEF OVER ANOTHER.

    Toulmin on Ideals of Natural Order.Richard L. Purtill - 1971 - Synthese 22 (3-4):431 - 437.
    In this paper I criticize Toulmin's concept of Ideals of Natural Order and his account of the role these Ideals play in scientific explanation as given in his book, Foresight and Understanding. I argue that Toulmin's account of Ideals of Natural Order as those theories taken to be self evident by scientists at a given time introduces an undesirable subjectivism into his account of scientific explanation. I argue also that the history of science, especially the recent history of microphysics, does (...)

    Lord of the Elves and Eldils: Fantasy and Philosophy in C. S. Lewis and J. R. R. Tolkien.Richard L. Purtill - 1974 - Grand Rapids: Zondervan Pub. House.
    "[This book] is a fascinating look at the fantasy and philosophy of C. S. Lewis and J. R. R. Tolkien. The two men were friends and fellow professors at Oxford, renowned Christian thinkers who both 'found it necessary to create for the purposes of their fiction other worlds—not utopias or dystopias, but different worlds.'" --.

    Thinking About Religion a Philosophical Introduction to Religion.Richard L. Purtill - 1978 - Prentice-Hall.
    This introduction to philosophy of religion is aimed at the problems which most interest students. As the author explains in his preface, "Students today have a wide range of perplexities about religion, many of them theological or historical rather than philosophical... The topics I have covered in this book are those which I have found to create the most interest and cause the most discussion when they have come up in class.".

    In a recent book, J. R. Lucas presents an argument to show that if God has infallible knowledge of the future, our will is not free. Thus, Lucas concludes, like the medieval Jewish philosopher Gersonides, that God in creating beings with genuinely free will, abdicates some of his omniscience as well as some of his omnipotence. God could, but will not, determine our choices, since such an exercise of his power would rob us of free will. Similarly, Lucas holds, God (...)

    Michael Dummett's new book is the greatly expanded and recently revised version of his distinguished William James Lectures, delivered in 1976. Dummett regards the construction of a satisfactory theory of meaning as the most pressing task of contemporary analytical philosophy. He believes that the successful completion of this difficult assignment will lead to a resolution of problems before which philosophy has been stalled, in some instances for centuries. These problems turn on the correctness or incorrectness of a realistic view of (...)

    Kuhn on Scientific Revolutions.Richard L. Purtill - 1967 - Philosophy of Science 34 (1):53-58.
    T. S. Kuhn's book, The Structure of Scientific Revolutions, [1], is a long and complex work, containing a large number of examples and arguments bearing on questions in the philosophy, history, and sociology of science. My treatment of it here will necessarily be limited, but I will try to state its main theses and discuss them insofar as this can be done without detailed examination of the examples cited from the history of science.

    Disembodied Survival Again.Richard L. Purtill - 1977 - Canadian Journal of Philosophy 7 (1):125 - 132.
    In a recent paper, I challenged a currently fashionable argument against the intelligibility of disembodied survival. This argument urges that only bodily continuity can provide a satisfactory criterion for personal identity and since bodily continuity is, of course, ruled out ex hypothesi in disembodied survival, we could have no satisfactory criterion for identity of a disembodied person. Toward the end of the paper I issued a challenge to supporters of this argument; if there are reasonable standards for a criterion of (...)

    Flew and the Free Will Defence: RICHARD L. PURTILL.Richard L. Purtill - 1977 - Religious Studies 13 (4):477-483.
    In a recent paper Anthony Flew gives an argument which can be outlined as follows: 1. Any attempt to give a ‘free will defence’ must be based either on a compatibilist notion of free will or a libertarian, incompatibilist, notion of free will. 2. A free will defence based on a compatibilist notion of free will must fail, for on a compatibilist view of free will, God could make creatures who were free but never chose evil. 3. A free will (...)
