Recorded talks on Catholic Philosophers


Catholic Philosophers Across the Ages (2017) is a series of twenty-four talks on Catholic Philosophers, professionally recorded by Now You Know Media, and soon to be available in audio versions
. The talks are on BEGINNINGS (Introduction; The Bible, Plato, and Aristotle; Aristides, Justin, Clement, and Tertullian; Irenaeus clarifies the problem of evil; Menucius Felix debates non-believers; Origen criticizes biblical fundamentalism; Augustine converts to Christianity; and Augustine on Christian doctrine); MIDDLE (The Middle Ages through Anselm; Arguments for God's existence; Aquinas on faith and reason; Aquinas on God as first cause; Aquinas on God as the world's designer; Aquinas and the natural moral law; Ockham, Loyola, and Galileo; and Descartes); and RECENT (Catholic philosophy in transition, The loss of faith among intellectuals, Teilhard and evolution, Stein on woman's special value, Callahan on pro-life feminism, Copleston debates Russell, Plantinga on Christian philosophy, and Rescher and John Paul II). These talks are based on my Anthology of Catholic Philosophy.

Introduction to Logic, third edition

Introduction to Logic, third edition (New York and London: Routledge, 2017), 414 pages, with the companion
LogiCola instructional program and a Teacher Manual [not yet done]: a basic and intermediate logic text. This is a thorough rewrite of the second edition. The preface talks about improvements.

Ethics and Religion

Ethics and Religion, (New York and London: Cambridge University Press, 2016), 196 pages. This book develops strong versions of both divine command theory (which sees God's will as creating the moral order) and natural law (which accepts ethical truths that don't depend on God's will but perhaps depend on his reason or creation). It also deals with how atheists object on ethical grounds to belief in God and how they view ethics; it defends belief from their objections. It also explores related topics, such as practical reason, the golden rule, ethics and evolution, the problem of evil, and the fine-tuning argument. Click

Recorded talks on the Golden Rule

The Golden Rule: A Moral Ideal for the World (2013) is a series of twelve talks on the golden rule,
professionally recorded by Now You Know Media, and available in video and audio versions. The talks are on BASICS (Introduction, Fallacies, and Stories); PRACTICE (Moral education, Egoism and evolution, and Applied ethics); RELIGION (Christianity, Interfaith dialogue, and Non-Christian faiths); and HISTORY (Before 1900 -- this one is online as a sample, The slavery debate, and Since 1900). These talks are based on my Ethics and the Golden Rule.

Ethics and the Golden Rule

Ethics and the Golden Rule (New York and London: Routledge, 2013), a fairly comprehensive treatment of the
golden rule ("Treat others as you want to be treated"). It covers a wide range of topics, such as how the golden rule connects with world religions and history, how it applies to practical areas like moral education and business, and how it can be understood and defended philosophically. I wrote this to be a "golden-rule book for everyone," from students to general readers to specialists. Click here for a video overview or here to preview the first 30 pages.
