It is widely acknowledged Einstein and Newton were some of the greatest thinkers in history. They didn’t start out as exceptional though. Einstein had a slow development as a child while Newton could only get through 2 or 3 pages a day in scientific reading when starting out. All this to say to not get discouraged by weighty philosophical writing.
Cornelius Van Til is the author of this article and he shows clearly the progression of thought from Plato and Aristotle through Aquinas then Kant as opposed to the revelation of God in scripture. In the end there are only two positions: autonomous man who by definition (self-rule) is his own god, and the truth of scripture. Van Til speaks of the Westminster Confession and Calvin but it should be nuanced to indicate the grammatical-historical reading (plain sense) of scripture.
