Last night, we had a guest speaker (Greg Koukl of Stand to Reason) for one of my classes. He was a great guy, and I really enjoyed listening to and talking with him. But, he said one thing I had never heard before (well, he said several, but this one made me curious): he believes Francis Schaffer was an evidentialist and not a presuppositionalist. Has anyone heard this claim before? Was Schaffer an evidentialist and I have just never realized it?
