The origins of life remains one of the great unsolved mysteries of science. Growing evidence suggests that the first organisms lived deep underground, in environments previously thought to be uninhabitable, and that microbes carried inside rocks have travelled between Earth and Mars. But the question remains: how can life spring into being from non-living chemicals? THE FIFTH MIRACLE reveals the remarkable new theories and discoveries that seem set to transform our understanding of life's role in the unfolding drama of the cosmos.

In contemporary discussions of abortion, both sides argue well-worn positions, particularly concerning the question, When does human life begin? Though often invoked by the Catholic Church for support, Thomas Aquinas in fact held that human life begins after conception, not at the moment of union. But his overall thinking on questions of how humans come into being, and cease to be, is more subtle than either side in this polarized debate imagines. Fabrizio Amerini—an internationally-renowned scholar of medieval philosophy—does justice to Aquinas’ views on these controversial issues. Some pro-life proponents hold that Aquinas’ position is simply due to faulty biological knowledge, and if he knew what we know today about embryology, he would agree that human life begins at conception. Others argue that nothing Aquinas could learn from modern biology would have changed his mind. Amerini follows the twists and turns of Aquinas’ thinking to reach a nuanced and detailed solution in the final chapters that will unsettle familiar assumptions and arguments. Systematically examining all the pertinent texts and placing each in historical context, Amerini provides an accurate reconstruction of Aquinas’ account of the beginning and end of human life and assesses its bioethical implications for today. This major contribution is available to an English-speaking audience through translation by Mark Henninger, himself a noted scholar of medieval philosophy.

Many of the most controversial moral decisions we face hinge upon competing descriptions of life, and never is this truer than at the beginning of life. James Mumford draws upon phenomenology (a branch of continental philosophy) to question the descriptive adequacy, the essential "purchase upon reality," of many of the approaches, attitudes and arguments which make up beginning of life ethics today. He argues that many of the most prevalent positions and practices in our late modern culture have simply failed to take into account the reality of human emergence, the particular way that new members of our species first appear in the world. Historically, phenomenologists have been far more interested in death than in birth. Mumford therefore first develops his own phenomenological investigation of human emergence, taking leads and developing approaches from phenomenologists both French and German, both living and dead. In the second half of the book phenomenology is finally applied to ethics, and acute moral questions are divided into two kinds: first those concerning "what" it is that we are dealing; and, secondly, the more contextual "where" questions relating to the situation in which the subject is found. Finally, although this book primarily constitutes a philosophical rather than a religious critique of contemporary ethics, with the findings from continental philosophy being brought to bear upon core convictions of English-speaking 'liberal' moral and political philosophers, Mumford concludes by exploring an alternative theological basis for human rights which might fill the vacuum created.

In this fascinating journey to the edge of science, Vidal takes on big philosophical questions: Does our universe have a beginning and an end or is it cyclic? Are we alone in the universe? What is the role of intelligent life, if any, in cosmic evolution? Grounded in science and committed to philosophical rigor, this book presents an evolutionary worldview where the rise of intelligent life is not an accident, but may well be the key to unlocking the universe's deepest mysteries. Vidal shows how the fine-tuning controversy can be advanced with computer simulations. He also explores whether natural or artificial selection could hold on a cosmic scale. In perhaps his boldest hypothesis, he argues that signs of advanced extraterrestrial civilizations are already present in our astrophysical data. His conclusions invite us to see the meaning of life, evolution and intelligence from a novel cosmological framework that should stir debate for years to come.

This collection of essays examines alternative theories about persons and personal identity at the beginning and end of life. The contributions seek to answer the important question, When does a person begin and cease to exist? Organized chronologically, these works address three broad topics: theories of persons, persons at the beginning of life, and persons at the end of life. The first section offers differing views on the nature of persons that have influenced ontological and bioethical discussions of the subject. Essays in the next section track the debate over abortion and the moral status of embryos. The last section explores alternative definitions and determinations of death. This book is a useful resource for examining the connection between theoretical and bioethical considerations about persons.

This edition of Science and Creationism summarizes key aspects of several of the most important lines of evidence supporting evolution. It describes some of the positions taken by advocates of creation science and presents an analysis of these claims. This document lays out for a broader audience the case against presenting religious concepts in science classes. The document covers the origin of the universe, Earth, and life; evidence supporting biological evolution; and human evolution. (Contains 31 references.) (CCM)
