In reading Dr. Gordon H. Clark's theological and philosophical works, I came to see that logic was the most important source for understanding anything at all. Without logic nothing makes sense. Yet the liberals will say that learning is intuitive, experiential, emotional and a whole host of other things.
The difference between naturalism and theism--between the latest scientific opinions on evolution and creation; between the Freudian animal and the image of God; between belief in God and atheism--is based on their two different epistemologies. Naturalism professes to learn by observation and analysis of experience; the theistic view depends on Biblical revelation. No amount of observation and analysis can prove the theistic position. Of course, no amount of observation and analysis can prove evolution or any other theory. The secular philosophies all result in total skepticism. In contrast, theism bases its knowledge on divinely revealed propositions. They may not give us all truth; they may even give us very little truth; but there is no truth at all otherwise. So much for the secular alternative.
Therefore the Christian evaluation of subjects in the curriculum and of pupils or students in school is rational and intellectualistic, in opposition to the emotionalism and anti-intellectualism of the present age.
