Rolheiser points readers to the proximity of God in the seeming insignificance of life. He sheds new light on issues such as marriage and family life and the presence of God, loneliness and sexuality, language and prayer, and most of all, the all-encompassing, unconditional love of God.

Moral thinking today finds itself stranded between the particular and the universal. Alasdair MacIntyre's work on narrative, discussed here along with that of Stanley Hauerwas and H. T. Engelhardt, aims to undo the perceived damage done by the Enlightenment by returning to narrative and abandoning the illusion of a disembodied reason that claims to be able to give a coherent explanation for everything. It is precisely this - a theory that holds good for all cases - that John Rawls proposed, drawing on the heritage of Emmanuel Kant. Who is right? Must universality be abandoned? Must we only think about morality in terms that are relative, bound by space and time? Alexander Lucie-Smith attempts to answer these questions by examining the nature of narrative itself as well as the particular narratives of Rawls and St Augustine. Bound and rooted as they are in history and personal experience, narratives nevertheless strain at the limits imposed on them. It is Lucie-Smith's contention that each narrative that points to a lived morality exists against the background of an infinite horizon, and thus it is that the particular and the rooted can also make us aware of the universal and unchanging.

This monograph deals with various classes of deterministic continuous time optimal control problems wh ich are defined over unbounded time intervala. For these problems, the performance criterion is described by an improper integral and it is possible that, when evaluated at a given admissible element, this criterion is unbounded. To cope with this divergence new optimality concepts; referred to here as "overtaking", "weakly overtaking", "agreeable plans", etc. ; have been proposed. The motivation for studying these problems arisee primarily from the economic and biological aciences where models of this nature arise quite naturally since no natural bound can be placed on the time horizon when one considers the evolution of the state of a given economy or species. The reeponsibility for the introduction of this interesting class of problems rests with the economiste who first studied them in the modeling of capital accumulation processes. Perhaps the earliest of these was F. Ramsey who, in his seminal work on a theory of saving in 1928, considered a dynamic optimization model defined on an infinite time horizon. Briefly, this problem can be described as a "Lagrange problem with unbounded time interval". The advent of modern control theory, particularly the formulation of the famoue Maximum Principle of Pontryagin, has had a considerable impact on the treatment of these models as well as optimization theory in general.

The author of The Holy Longing explores the debilitating obsessions that often dominate our lives and offers down-to-earth guidance for learning to leave our fears, anxieties, and guilt “forgotten among the lilies.” “Rarely do we taste the food we eat or the coffee we drink. Instead we go through our days too preoccupied, too compulsive, and too dissatisfied to really be able to be present for and celebrate our own lives,” Ronald Rolheiser writes in the introduction to this powerful collection of essays. Forgotten Among the Lilies shows that there is a better way to find contentment and joy. Only by trusting in God’s grace and providence, Rolheiser argues, can we move beyond our obsessions and rejoice in what we have and who we are. With his trademark blend of insight, compassion, and honesty laced with humor, the author teaches that it is possible to experience freedom instead of anxiety, solitude instead of loneliness, and a generosity of spirit that returns to the giver far more than it costs.

From the author of the bestselling, The Holy Longing, comes a book about the central expression of faith for hundreds of millions of Christians, the Eucharist. More so than anything else, the Eucharist is what anchors many peoples' life, prayer, and ultimately the way they live their lives. In this deeply personal book, Father Ronald Rolheiser delves into the history and meaning of this sacred tradition, drawing upon the insights of various scripture scholars, theologians, and church teachings. With personal warmth and great insight, he reflects on his own particular Roman Catholic upbringing and the centrality that the Eucharist has within that tradition. At the same time, he looks at other denominations’ traditions around the Eucharist. Our One Great Act of Fidelity is an investigation into the ways people secure their faith and belief and discover true intimacy with God and each other. Ultimately, however, it is a spiritual and a personal statement of how Ronald Rolheiser understands the Eucharist and why he celebrates it every day. Ronald Rolheiser is a specialist in the field of spirituality and is currently President of the Oblate School of Theology in San Antonio, Texas. Father Rolheiser is the author of The Holy Longing, The Restless Heart, Forgotten Among the Lilies, The Shattered Lantern, and Against an Infinite Horizon. He writes a weekly column that appears in more than 90 Catholic publications. More information on his work can be found at RonRolheiser.com.

Ronald Rolheiser makes sense of what is frequently a misunderstood word: spirituality. In posing the question "What is spirituality?" Father Rolheiser gets quickly to the heart of common difficulties with the subject, and shows through compelling anecdotes and personal examples how to channel that restlessness, that deep desire, into a healthy spirituality. This book is for those searching to understand what Christian spirituality means and how to apply it to their own lives. Rolheiser explains the nonnegotiables--the importance of community worship, the imperatives surrounding social action, the centrality of the Incarnation, the sustenance of the spiritual life--and how spirituality necessarily impacts every aspect of human experience. At the core of this readable, deeply revealing book is an explanation of God and the Church in a world that more often than not doubts the credibility of both.
