Francis Schaeffer exposes the real snake (false philosophical premises) in the woodpile (the church) in this lecture which covers briefly, much of the material in his book 'The God Who is There'. (Which I have read.)
It is good to hear his voice, and his unapologetic stand for faith in the ultimate reality of God's character, but this talk is not for the faint-hearted, as he - equally unapologetically - marches through his material.
