How should a Christian think? If a serious Christian wants to think seriously about a serious subject--from considering how to vote in the next election to choosing a career; from deciding among scientific theories to selecting a mate; from weighing competing marketing proposals to discerning the best fitness plan--what does he or she do? This basic question is at the heart of a complex discourse: epistemology. A bold new statement of Christian epistemology, Need to Know presents a comprehensive, coherent, and clear model of responsible Christian thinking. Grounded in the best of the Christian theological tradition while being attentive to a surprising range of thinkers in the history of philosophy, natural science, social science, and culture, the book offers a scheme for drawing together experience, tradition, scholarship, art, and the Bible into a practical yet theoretically profound system of thinking about thinking.John Stackhouse's fundamental idea is as simple as it is startling: Since God calls human beings to do certain things in the world, God can be relied upon to supply the knowledge necessary for human beings to do those things. The classic Christian concept of vocation, then, supplies both the impetus and the assurance that faithful Christians can trust God to guide their thinking--on a "need to know" basis.
