It seems to me that the best philosophers begin (or ought to begin) with two basic principles, one from Socrates, one from Aristotle: Know yourself, and ask the right preliminary questions.
If philosophers actually followed these two rules, they would realize that these two principles meld into one. If those philosophers asked whether or not they were capable of pursuing knowledge of God, and if they knew themselves well enough to understand the radically debilitating effects of sin on the human mind and heart, they would see that knowledge of God is beyond their reach. They would know that they do not know and cannot know. They would see that, even if the world outside us were a perfect revelation of God, our understanding of that revelation would inevitably be twisted, truncated and self-glorifying, and that in our narcissistic frenzy we would turn nature from a window for seeing God into a mirror that reflects only our own sinful selves and our own wicked doing. They’d realize what they do not realize now: Apart from revelation and a radical regeneration of our very selves, we are hopelessly adrift in a sea of divinely omnipotent fact with no compass, no North Star, and no rudder. We sail in ever-decreasing circles that spin tighter and tighter in upon ourselves. If they really knew themselves, and if they asked the right preliminary questions, they would realize the abject foolishness of considering themselves and their thoughts the measure of Heaven and earth. But in their current condition, this knowledge is beyond them. They do not know, and they do not know that they do not know. They are blind to their blindness.
In other words, the problem with combining philosophy and God begins with the philosophers. That problem can be fixed or transcended only by God.
I have yet to mention Satan, a supernatural deceiver posing as an angel of light against whom, apart from Christ, we have no defense. He is an enemy intent upon driving us from the Bible, not to it, and driving us from Christ, not to Him. He is an enemy who remembers what was done to him by the Bible in the hands of the One Who inspired it (Matt. 4: 1-11). He is an enemy determined to convince us of what we are already too willing to believe, namely that we are able to get to God without God, as if we did not need Christ to know God, and as if we were gods ourselves. Philosophers believe the Liar and his lies precisely because they do not acknowledge him and his works.
Remember: You are most likely to become an unwitting agent of the enemy you neither recognize nor admit -- and philosophy does not recognize or admit the Devil and his doings. His self-appointed task is to blind the minds of unbelievers (2 Cor. 4: 4), Aristotle included. At that task he is an unquestioned expert. Against him we are no challenge. Satan fights unremittingly against eternal life, which is knowing God and His Son (John 17: 3). Never forget that philosophy is ill-equipped to resist Satan. It has not the tools necessary for the task because those tools have been removed from philosophy's armory at the outset: Philosophy permits no Bible in its work and no word from Christ. Philosophy has yet to come to grips with demonology and its own undefended exposure to relentless and colossal evil, against which only the blood of Christ prevails.
