We need a coherent picture of our world. Life's realities won't let us ignore its fundamental questions, but with so many opposing views, how will we choose answers that are reliable? In this series of books, David Gooding and John Lennox offer a fair analysis of religious and philosophical attempts to find the truth about the world and our place in it. By listening to the Bible alongside other leading voices, they show that it is not only answering life's biggest questions--it is asking better questions than we ever thought to ask. In Book 4 - Doing What's Right , Gooding and Lennox present particular ethical theories that claim to hold the basic principles everyone should follow. They compare the insights and potential weaknesses of each system by asking: what is its authority, its supreme goal, its specific rules, and its guidance for daily life? They then evaluate why even the best theories have proven to be impossible to follow consistently.
