Niels Bohr, the founding father of modern atomic physics and quantum theory, was as original a philosopher as he was a physicist. This study explores several dimensions of Bohr's vision: the formulation of quantum theory and the problems associated with its interpretation, the notions of complementarity and correspondence, the debates with Einstein about objectivity and realism, and his sense of the infinite harmony of nature. The author's chief attention is given to Bohr's epistemological lesson, the conviction that all our description of nature is dependent on the words we use and the ways we can unambiguously use them. Against those who would view Bohr as a vague positivist, the author argues here that Bohr is best understood as using transcendental arguments and shaping a kind of descriptive metaphysics in his defence of our abilities to offer a description of the world we live in.

Tricky Questions about God is a response to many requests made by Catholic teachers, catechists, and parents for help in answering the tricky and often highly intelligent questions that children and young people ask about their faith. The book begins with four foundational chapters: "Can theology be made simple?," "Why is the Bible important?," "Is faith reasonable?," and "Can expressions of faith change?" It then explores a series of questions like "Who made God?," "If God is almighty, why is there so much suffering?," and "Does God have a plan for me?". Each chapter draws on engaging stories and examples to illustrate points, as well as summarizing relevant elements of Scripture, Church teaching, and contemporary philosophy and science. While primarily designed as a resource for teachers, the work could also be helpful in RCIA programs, faith formation programs for adults, and identity development programs for lay leaders in Catholic ministries.

A book that helps teachers answer the tricky questions that students ask about God, using a fresh and accessible account of Scripture, church teaching, theology, and contemporary learning.
