All people have a worldview. All people answer ultimate questions about truth and reality, whether consciously or unconsciously. And all people act according to those answers. Understand the big questions and the ways people answer them, and you'll have real insight into the thinking and behavior of those around you.
In A Blueprint for Thinking, R.C. Sproul examines the big questions. He explores the basic elements of every worldview: epistemology (How we know what is true); metaphysics (how we know what is real); theology (discovering who God is); anthropology (discovering who man is); and ethics (discovering what right and wrong is). He also proves that the Christian answers to those questions are the truthful ones.
If you want to conform your own worldview to Christ's, and help others do the same, A Blueprint for Thinking is for you.
