Who am I? Why am I here? Where do I find meaning? Life is full of big questions. The study of philosophy seeks answers to such questions. In his latest book, prolific author Vern Poythress investigates the foundations and limitations of Western philosophy, sketching a distinctly Christian approach to answering basic questions about the nature of humanity, the existence of God, the search for meaning, and the basis for morality. For Christians eager to engage with the timeless philosophical issues that have perplexed men and women for millennia, this is the place to begin.

Feeling overwhelmed and unproductive? The answer isn’t to do more. What image forms in your mind when you think of productivity? An assembly line? Spreadsheets? Business suits or workplace uniforms? In the ancient world, productivity didn't conjure images like these. Instead, it referred to crop yield and fruit bearing. This agrarian imagery helps us understand productivity through a biblical lens. Jesus taught, By this my Father is glorified, that you bear much fruit (John 15:8). Who doesn’t want to have a truly productive life—to bear much fruit? But how does this happen in the places we hold dear—the home, workplace, and in our communities? We often feel overworked and overrun, defeated and discouraged. The world says be productive so that you can get all you can out of this life. The Bible says be productive so you can gain more of the next life. In Redeeming Productivity, author Reagan Rose explores how God’s glory is the purpose for which He planted us. And he shows how productivity must be firmly rooted in the gospel. Only through our connection to Christ—the True Vine—are we empowered to produce good fruit. This book shows how we can maintain the vitality of that connection through simple, life-giving disciplines. Readers will discover manageable applications like giving God the first fruits of our days. Additionally, Reagan discusses how our perspective on suffering is transformed as we see trials as God’s pruning for greater productivity.

Many people think science is antagonistic to Christian belief. Science, it is said, shows that the universe is billions of years old, while the Bible says it is only thousands of years old. And some claim that science shows supernatural miracles are impossible. These and other points of contention cause some Christians to view science as a threat to their beliefs. Redeeming Science attempts to kindle our appreciation for science as it ought to be-science that could serve as a path for praising God and serving fellow human beings. Through examining the wonderfully complex and immutable laws of nature, author Vern Poythress explains, we ought to recognize the wisdom, care, and beauty of God. A Christian worldview restores a true response to science, where we praise the God who created nature and cares for it.

What does Christianity have to do with the study of mathematics? Prolific writer and scholar Vern Poythress offers a startling answer to this perplexing question: everything. This groundbreaking book argues that the harmony of abstract mathematical truths, the physical world of things, and the personal world of our thinking depends on the existence of the Christian God. With advanced degrees in mathematics and New Testament studies, Poythress shows that these distinct “perspectives” on mathematics cohere because all three find their origin in God’s consistent character and nature. Whether it’s simple addition and subtraction or more complex mathematical concepts such as set theory and the nature of infinity, this comprehensive book lays a theistic foundation for all mathematical inquiry.

A renewed focus on the role of interpersonal relationships in the cultivation of religious sensibilities is emerging in the study of religion. Matthew Ryan Robinson addresses this question in his study of Friedrich Schleiermacher's notion of "free sociability". In Schleiermacher's ethics, the human person is formed in and consists of intimate, tightly interconnecting relationships with others. Schleiermacher describes this sociability as a natural tendency prompted by experiences of physical and existential limitation that lead one to look to others to complete one's experience. But this experience of incompleteness and orientation to "the completion of humanity" also constitute the fundamental structure of religion in Schleiermacher's theory of religion as orientation to "the universe and the relationship of humanity to it." Thus, Schleiermacher not only presents sociability as basic to human nature, but also as inherently religious - and, potentially, redemptive.

Interpersonal relationships are possible for humans because we are created in the image of a Trinitarian God. But if the Trinity is our model for relationships, why is the human condition rife with pain and evil? How are we to think correctly about fallen human relationships and our models for understanding them? Redeeming Sociology advocates a biblically informed model for human relationships—relationships rooted in the Trinitarian character of God, his governance of the world, and his redemption accomplished in Christ. Poythress examines how the breaking of relationships through sin leads to strife, murder, and oppression among human beings and sets cultures against one another. And he shows how these broken relationships are restored through the outworking of redemption in Christ. Though typical sociological models for interpersonal relationships may offer some valuable insights, they are handicapped by a fundamental misunderstanding of humanity. The biblical model that Poythress presents correctly diagnoses the problem of human relationships, so it can likewise prescribe a biblical solution that infuses new meaning and power into how we relate to others made in the image of God.

Now in paperback, Forming Humanity reveals bildung, or ethical formation, as the key to post-Kantian thought. Kant’s proclamation of humankind’s emergence from “self-incurred immaturity” left his contemporaries with a puzzle: What models should we use to sculpt ourselves if we no longer look to divine grace or received authorities? Deftly uncovering the roots of this question in Rhineland mysticism, Pietist introspection, and the rise of the bildungsroman, Jennifer A. Herdt reveals bildung, or ethical formation, as the key to post-Kantian thought. This was no simple process of secularization, in which human beings took responsibility for something they had earlier left in the hands of God. Rather, theorists of bildung, from Herder through Goethe to Hegel, championed human agency in self-determination while working out the social and political implications of our creation in the image of God. While bildung was invoked to justify racism and colonialism by stigmatizing those deemed resistant to self-cultivation, it also nourished ideals of dialogical encounter and mutual recognition. Herdt reveals how the project of forming humanity lives on in our ongoing efforts to grapple with this complicated legacy.

For the well-rounded Christian looking to improve their critical thinking skills, here is an accessible introduction to the study of logic (parts 1 & 2) as well as an in-depth treatment of the discipline (parts 3 & 4) from a professor with 6 academic degrees and over 30 years experience teaching. Questions for further reflection are included at the end of each chapter as well as helpful diagrams and charts that are appropriate for use in high school, home school, college, and graduate-level classrooms. Overall, Vern Poythress has undertaken a radical recasting of the study of logic in this revolutionary work from a Christian worldview.

Vern Poythress, one of today's leading Reformed theologians, has made many vital contributions to evangelical scholarship— particularly a vision to glorify Christ as Lord over all areas of human life in order to redeem all realms of human thought. In honor of his many years of faithful thinking and writing, twenty evangelical scholars have come together to produce a set of essays on topics of importance throughout his ministry: biblical exegesis, the doctrine of the Trinity, worldview, history, and ethics.
