Aquinas needs no introduction as one of the greatest minds of the middle ages. Highly influential on the development of Christian doctrine, his ideas are still of fundamental philosophical importance. This new critique of his natural law theory discusses the theory's background in Aristotle and advances new interpretations of contemporary legal issues which hark back to Aquinas.

Certain scholars wish to acquit St. Thomas Aquinas of the “illicit inference from facts to norms” commonly referred to as the naturalistic fallacy. Seeing in certain passages his awareness of illegitimate ways to derive morality from natural ends, many have come to read Aquinas as agreeing with the view that knowledge of the moral order does not derive from knowledge of human nature and of the natural ends of its parts and powers. This paper aims to expose the deficiencies of (...) this reading as a way of bringing more fully into view the whole thought of Aquinas on the question.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

Profoundly important ethical and political controversies turn on the question of whether biological life is an essential aspect of a human person, or only an extrinsic instrument. Lee and George argue that human beings are physical, animal organisms - albeit essentially rational and free - and examine the implications of this understanding of human beings for some of the most controversial issues in contemporary ethics and politics. The authors argue that human beings are animal organisms and that their personal identity (...) across time consists in the persistence of the animal organisms they are; they also argue that human beings are essentially rational and free and that there is a radical difference between human beings and other animals; criticize hedonism and hedonistic drug-taking; present detailed defenses of the prolife positions on abortion and euthanasia; and defend the traditional moral position on marriage and sexual acts.

The liberal view that valid consent is sufficient for a sex act to be morally legitimate is challenged by three major philosophies of sex: the Catholic view of sex as ordained for procreation and properly confined to marriage, the romantic view of sex as bound up with love, and the radical feminist analysis of sex in our society as part and parcel of the domination of women by men. I take a critical look at all three, focusing on Mary Geach''s (...) recent statement of the procreation view, Roger Scruton''s theory of sexual desire as naturally evolving into intimacy and love, and several radical feminist discussions of sex in sexist society which argue that the notion of consent is unhelpful and, indeed, irrelevant. I argue that none of these lines of argument is convincing, and that consent remains the touchstone of morally permissible sex – although, dmittedly, it may not be very helpful in discussing ideals of human sexuality.

This book defends the conjugal view of marriage. Patrick Lee and Robert P. George argue that marriage is a distinctive type of community: the union of a man and a woman who have committed to sharing their lives on every level of their beings (bodily, emotionally, and spiritually) in the kind of union that would be fulfilled by conceiving and rearing children together. The comprehensive nature of this union, and its intrinsic orientation to procreation as its natural fulfillment, distinguishes marriage (...) from other types of community and provides the basis for the norms of marital exclusivity and permanence. Lee and George detail how the basic moral norms regarding sexual acts follow from the ethical requirement to respect the good of marriage and explain how the law should treat marriage, given its conjugal nature, examining both the same-sex-marriage issue and civil divorce.

This important philosophical reflection on love and sexuality from a broadly Christian perspective is aimed at philosophers, theologians, and educated Christian readers. Alexander R. Pruss focuses on foundational questions on the nature of romantic love and on controversial questions in sexual ethics on the basis of the fundamental idea that romantic love pursues union of two persons as one body. _One Body_ begins with an account, inspired by St. Thomas Aquinas, of the general nature of love as constituted by components (...) of goodwill, appreciation, and unitiveness. Different forms of love, such as parental, collegial, filial, friendly, fraternal, or romantic, Pruss argues, differ primarily not in terms of goodwill or appreciation but in terms of the kind of union that is sought. Pruss examines romantic love as distinguished from other kinds of love by a focus on a particular kind of union, a deep union as one body achieved through the joint biological striving of the sort involved in reproduction. Taking the account of the union that romantic love seeks as a foundation, the book considers the nature of marriage and applies its account to controversial ethical questions, such as the connection between love, sex, and commitment and the moral issues involving contraception, same-sex activity, and reproductive technology. With philosophical rigor and sophistication, Pruss provides carefully argued answers to controversial questions in Christian sexual ethics. "This is a terrific—really quite extraordinary—work of scholarship. It is quite simply the best work on Christian sexual ethics that I have seen. It will become the text that anyone who ventures into the field will have to grapple with—a kind of touchstone. Moreover, it is filled with arguments with which even secular writers on sexual morality will have to engage and come to terms." —_Robert P. George, Princeton University __ "_One Body_ is an excellent piece of philosophical-theological reflection on the nature of sexuality and marriage. This book has the potential to become a standard go-to text for professors and students working on sex ethics issues, whether in philosophy or theology, both for the richness of its arguments, and the scope of its coverage of cases. " — Christopher Tollefsen, University of South Carolina_ "Alexander Pruss here develops sound and humane answers to the whole range of main questions about human sexual and reproductive choices. His principal argument for the key answers is very different from the one I have articulated over the past fifteen years. But his argumentation is at every point attractively direct, careful, energetic in framing and responding to objections, and admirably attentive to realities and the human goods at stake." —_John Finnis, University of Oxford _.

"This volume is a work in Christian apologetics which attempts to state and defend some of the arguments which support the rationality of the Christian faith."--Page 11.

In this paper I argue that the existence of human reason gives us good reason to suppose that God exists. If the world were as the materialist supposes it is, then we would not be able to reason to the conclusion that this is so. This contention is often challenged by the claim that mental and physical explanations can be given for the same event. But a close examination of the question of explanatory compatibility reveals that the sort of explanation (...) that would have to be given for the event of, say, inferring that atheism is true, is incompatible with the event being explicable as a purely physical product of a purely physical universe.

A very liberal sexual ethics now holds sway in Western culture, such that mutual consent alone is widely seen as morally legitimizing almost any sexual activity between adults. It is further commonly assumed by both philosophers and nonphilosophers that arguing for some alternative to liberal sexual ethics requires appeal to ethical commands specific to some religious tradition or other. The purpose of this paper is to challenge that assumption by suggesting some purely naturalistic and independently-plausible premises that can be used (...) to argue for a much more conservative system of sexual ethics than is widely accepted today.

Tim Mawson argues that moral values hold objectively.

Critics of homosexual activity often appeal to some form of natural law theory as a basis for their arguments. According to one version of natural law theory, actions that “pervert” or misuse a bodily faculty are immoral. In this paper, I argue that this “perverted faculty argument” provides a successful account of good and evil action. Several objections are assessed and found inadequate.

_What _is_ the meaning of sex?_ Everyone in every time and place is interested in sex. Our own time is obsessed by it. One would think that a society obsessed by sex would understand it very well. But the truth is that obsession drives out understanding. We no longer understand even the common sense of sexuality, the things that were common knowledge in supposedly less enlightened times. Acclaimed philosopher J. Budziszewski remedies this problem. His wise, gracefully written book about the (...) nature, meaning, and mysteries of sexuality restores lost wisdom, raising and answering such questions as: Does sex have to mean anything at all? What is the meaning of the sexual powers, of sexual differences, of sexual love, of sexual beauty, of sexual purity? Is sexuality “all about sex”? why does sexuality stir up such transcendent longings for something more than sex? __On the Meaning of Sex__ corrects the most prevalent errors about sex, particularly the errors of the sexual revolution, which by mistaking pleasure for a good in itself has caused untold pain and suffering. In restoring the meaning and purpose of sex, the author reclaims what Dante calls “the intelligence of love.” “Looking out over the sexual landscape of our time,” Budziszewski writes, “I see a terrain of unutterable sweetness, despoiled by unmentionable pain. Yet who knows? Perhaps it is not too late to redeem the unutterable sweetness. Shall we try to find out?”. (shrink)

For the last twenty years John Corvino has traversed the US responding to moral and religious arguments against same-sex relationships. In this timely book, he shares that experience-both by addressing the standard objections and by offering insight into the culture wars more generally. In the process, he makes a fresh case for moral engagement, forcefully rejecting the idea that morality is a 'private matter'.

I argue for the rational inescapability of value objectivism, the thesis that at least some normative appraisal is not simply a matter of how, subjectively, we feel about the world; it is a matter of how, objectively, the world ought to be. I do this via a two-stage argument, the first stage of which is based around a thought experiment, the second stage of which is based on how those who reject the argument of the first stage must present their (...) doing so to themselves if they are to consider themselves rationally justified. I sketch a way in which this argument might lead one rationally to favour moral objectivism. (shrink)
