Subtitle on cover: 350 + ways your mind can help you become a saint.

"Kreeft shows how Tolkien gives a very convincing myth or vision which makes sense of reality and gives arguments for them. This is an exciting and insightful book."

What would happen if Socrates--yes, the Socrates of ancient Athens--suddenly showed up on the campus of a major university and enrolled in its divinity school? What would he think of human progress since his day? How would he react to our values? To our culture? And what would he think of Jesus? Peter Kreeft, Christian philosopher and longtime admirer of the historic Socrates, imagines the result. In this drama Socrates meets such fellow students as Bertha Broadmind, Thomas Keptic and Molly Mooney. Throughout, Kreeft weaves an intriguing web as he brings Socrates closer and closer to a meeting with Jesus. Here is a startling and provocative portrayal of reason in search of truth. In a new introduction to this revised edition, Kreeft also highlights the inspiration for this book and the key questions of truth and faith it addresses.

Peter Kreeft brings his unique insights to this most important area of our spiritual lives. He claims he himself is still a beginner in prayer, and this book is for all those, like him, who feel that they are not good at praying but desire to become much better at it. Thus, Kreeft offers simple, but profound advice and practical steps for developing a prayer life based on the time-tested wisdom of the saints and great spiritual writers, especially the principles found in Brother Lawrence's classic, The Practice of the Presence of God.In short, straight-forward and unsentimental chapters, Kreeft covers all the key areas for understanding and developing that intimate form of communication with our Creator that we call prayer. He covers such areas as the necessity of prayer, various motives and methods, steps, patience, suffering, sin, faith, and grace.

A shortened version of Kreeft's much larger Summa of the Summa, which in turn was a shortened version of the Summa Theologica. The reason for the double shortening is pretty obvious: the original runs some 4000 pages! (The Summa of the Summa was just over 500.) The Summa is certainly the greatest, most ambitious, most rational book of theology ever written. In it, there is also much philosophy, which is selected, excerpted, arranged, introduced, and explained in footnotes here by Kreeft, a popular Thomist teacher and writer. St. Thomas Aquinas is universally recognized as one of the greatest philosophers who ever lived. His writings combine the two fundamental ideals of philosophical writing: clarity and profundity. He is a master of metaphysics and technical terminology, yet so full of both theoretical and practical wisdom. He is the master of common sense. The Summa Theologica is timeless, but particularly important today because of his synthesis of faith and reason, revelation and philosophy, and the Biblical and the classical Greco-Roman heritages. This little book is designed for beginners, either for classroom use or individually. It contains the most famous and influential passages of St. Thomas' philosophy with copious aids to understanding them.

In response to actual questions many people have asked him about angels & demons, well-known author and philosophy professor Peter Kreeft separates fact from fantasy and myth from reality as he answers 101 common questions about these spiritual beings. Based on a very popular college course he teaches on this subject, this book responds to the incredible amount of interest in angelic beings and attempts to clear up some of the misinformation abounding in numerous books today on what we really know about these mysterious spirits.

Peter Kreeft's Socrates enters the debate on abortion, considering the arguments of psychology, medicine and philosophy.

An author and professor presents the objective logical arguments against abortion; the subjective, personal motives of the pro-life position; and how these two factors influence the dialog between the two sides of the abortion issue.

Peter Kreeft has finally produced his own Summa. His admirers have been waiting for it for years without quite knowing what they were waiting for. Kreeft asks all the basic questions. He answers them, an even greater feat. Nothing is more needed in our academic world than a systematic working through of all the most important questions - both the ones we ask and the ones we should ask. Not only are the questions here but also the most sensible answers. No one else could do this welcome intellectual service quite so well or with quite so much wit and wisdom. The "reason" of the faith shines nowhere more clearly or more persuasively than in the work of Peter Kreeft. With this book, we have his finest gift to us, an account of the intelligibility of things, one that both makes sense and makes us aware of the vast wisdom that lies in the human mind and in the revelation addressed to it. - James V. Schall, s.j., Georgetown UniversityFirst, Peter Kreeft imitated the Socratic dialogue form to put Socrates in conversation with Jesus, Hume, Descartes, Kant, and Machiavelli. Now, in Summa Philosophica, Kreeft employs the medieval quaestio debate format used so successfully by St. Thomas Aquinas in his Summa Theologiae. This tour-de-force takes up 110 perennial questions asked through the centuries. Kreeft covers questions about metaphysics, knowledge, and ethics, including, "Does evil disprove God's existence?", "Is time travel possible?", "Is the soul immortal?" and "Whether institutional religion has done more harm than good?" If you want a summary of all the most important questions in philosophy, as well as the most convincing answers to these questions, this book is the single most reliable and enjoyable guide available. - Christopher Kaczor, Loyola Marymount, is author of How to Stay Catholic in College and The Ethics of Abortion.

This new and revised edition of Peter Kreeft's Socratic Logic is updated, adding new exercises and more complete examples, all with Kreeft's characteristic clarity and wit. Since its introduction in the spring of 2004, Socratic Logic has proven to be a different type of logic text: . (1) This is the only complete system of classical Aristotelian logic in print. The "old logic" is still the natural logic of the four language arts (reading, writing, speaking, and listening). Symbolic, or "mathematical," logic is not for the humanities. (How often have you heard someone argue in symbolic logic?) (2) This book is simple and user-friendly. It is highly interactive, with a plethora of exercises and a light, engaging style. (3) It is practical. It is designed for do-it-yourselfers as well as classrooms. It emphasizes topics in proportion to probable student use: e.g., interpreting ordinary language, not only analyzing but also constructing effective arguments, smoking out hidden assumptions, making "argument maps," and using Socratic method in various circumstances. (4) It is philosophical. Its exercises expose students to many classical quotations, and additional chapters introduce philosophical issues in a Socratic manner and from a common- sense, realistic point of view. It prepares students for reading Great Books rather than Dick and Jane, and models Socrates as the beginner's ideal teacher and philosopher.

The Platonic tradition in Western philosophy is not just one of many equally central traditions. It is so much THE central one that the very existence and survival of Western civilization depends on it. It is like the Confucian tradition in Chinese culture, or the monotheistic tradition in religion, or the human rights tradition in politics. In the first of his eight lectures, Peter Kreeft defines Platonism and its "Big Idea," the idea of a transcendent reality that the history of philosophy has labeled "Platonic Ideas" or Platonic Forms. In the second lecture, he briefly explores Plato's two basic predecessors or sources, myth and Socrates; and then looks at 12 applications of the Forms in Plato's own dialogues. The third lecture covers the three most important modifications or additions to Plato himself in the Platonic tradition: Aristotle, Plotinus, and Augustine, each of whom gave the Forms a new metaphysical address. The fourth lecture explores six Christian Platonists, three in the New Testament and three philosophers, Justin Martyr, Bonaventure, and Aquinas. The next three lectures explore the consequences of the modern abandoning of Platonism, beginning with William of Ockham's Nominalism, as the source of nearly all modern philosophical errors, and its results in the Empiricism of Locke and Hume, the so-called Copernican Revolution in philosophy in Kant, the so-called "analytic philosophy," which still dominates English and American philosophy departments. In the sixth essays, Kreeft looks at 13 influential kinds of positivism or reductionism in modern thought: in method, history, metaphysics, epistemology, ethics, sociology, politics, logics, linguistics, sex, psychology, and theology, exemplified by Descartes, Machiavelli, Hobbes, Marx, Kant, Comte, Rousseau, Rawls, Ayer, Derrida, Freud, Skimmer, Nietzsche, and Sartre. Lecture 7 looks at the results of abandoning the Platonic tradition in ethics, the values vacuum, or nihilism, in Ecclesiastes, Pascal, Kierkegaard, Nietzsche, Heidegger, Sartre, Dostoyevsky, Tolstoi, Marcel, and Buber. In the last lecture, Kreeft looks at some experiential evidence for Platonism, doors out of the cave that are still open, signals of transcendence.

Looking at Jesus as a complete human being and philosopher, explores the most radical revolution in the history of philosophy--the differences Jesus made to metaphysics, epistemology, anthropology, and philosophical ethics and politics.

"No philosopher since Augustine had more strings to his bow than SK."

"Probably no single thinker since Jesus has influenced the thoughts and lives of more people living in the Western world today than Sigmund Freud. Even agnostics like William Barrett, in Irrational Man, and atheists like Nietzsche, agree that the single most radical change in the last thousand years of Western civilization has been the decline of religion. And the four most influential critics of religion have certainly been Nietzsche, Marx, Darwin, and Freud. Of the four, Freud is by far the most popular No name is more associated with, and in fact responsible for, "the sexual revolution" than Freud. And no revolution in history, at least none since the one around a cross and an empty tomb, and perhaps even none since the one around a snake and an apple, has been more life-changing, and has more potential to continue to be more radically life-changing in the future, than the sexual revolution. To see this, just read Huxley's Brave New World. (And remember that Huxley was far from being a theist.) Freud wore three hats. Freud was (1) a practicing psychoanalyst (indeed, the inventor of psychoanalysis), (2) a professional theoretical psychologist and sociologist, and (3) an amateur philosopher. This book explores only his philosophy, for that is the point of his intersection with Socrates. If Socrates is right in his deepest convictions about the power of reason and the importance of philosophy, Freud's philosophy is the ultimate source, foundation, explanation, and justification for his psychology"--

Kreeft takes the reader through the world of existentialist philosophy, posing questions that challenge the concepts that Sartre proposed. Based on an imagination dialogue between Socrates and Sartre that takes place in the afterlife, this profound and witty book makes an entertaining and informative exploration of modern philosophy"Peter Kreeft's work is (1) unfailingly brilliant, (2) intellectually agile, (3) astonishingly perspicacious, (4) gloriously orthodox, (5) Chestertonian aphoristic." - Thomas Howard, author of On Being Catholic

Humorous, frank, and insightful, this book challenges the reader to step in and take hold of what is right and to cast away what is wrong. Topics covered included such varied subjects as private property, the individual, the Three Philosophies of Man, women, individualism, and more. A wonderful introduction to philosophy for the neophyte, and a joy for the experienced student of thought. "Imagine two of the most influential thinkers of all time, and two of the most diametrically opposed, thrust together in a no holds barred debate about some of the most important questions: Does man move the world or is he only a puppet of forces beyond his control? Is there a human nature or only market forces? Is Communism the liberator of mankind or a deadly scourge? In Peter Kreeft's Socrates Meets Marx, the father of philosophy cross examines the founder of communism using the Communist Manifesto, details from the life of Marx himself, and the witnesses of history as evidence to be considered for judgment. If only every edition of the Communist Manifesto would have been bound together with a copy of this book, the world would be a much saner place." - Christopher Kaczor, author of Proportionalism and the Natural Law Tradition

Immanuel Kant is one of the greatest philosophers in history. But, as Peter Kreeft notes in this book, Kant is really two philosophers-a philosopher about how we know things (epistemology) and a philosopher of right and wrong (ethics). If he had written only on either topic, he would still be the most important and influential of the modern philosophers.

"Kreeft presents a Socratic examination of Hume's Enquiry concerning Human Understanding in relation to the skepticism of Hume, posing questions that challenge the concepts that Hume proposed. Kreeft states that Hume is the "most formidable, serious, difficult-to-refute skeptic in the history of modern thought." Kreeft invites the reader to take part in the process of refuting Hume's skeptical arguments, with the great insights of Socrates. Based on an imagination dialogue between Socrates and Hume that takes place in the afterlife, this profound and witty book makes an entertaining and informative exploration of modern philosophy"--
