<quote from Real Faith & Reason>
Somewhere in a nearby city, two philosophy professors engage in a heated debate. While one insists the only thing he “knows” is that he exists, the other argues that he can’t even “know” he exists. Each man represents a different branch of skeptical philosophy.
We get the word “philosophy” from two Greek words. “Philo” means “loving.” “Sophia” means “knowledge or wisdom.” How could anyone love knowledge and wisdom while denying that knowledge and wisdom exist? And if no one can know anything about anything, how can either professor know what they think they know? Strangely, they assume that the laws of logic have value. They aren’t skeptical about that, but they have no reason for thinking that logic has any value.
Another question comes to mind: what are they teaching their students, and why do they think it’s worth teaching?
These professors have chosen the thought-foundation of assumptions, so they base their thinking on unknowns that they treat as facts. Basing all reasoning on unknowns can work pragmatically if the assumptions happen to be correct, but those who base thinking on assumptions can’t be certain that their assumptions are correct. Not having truth as a starting point, they check to see if the assumptions lead to the conclusion they desire. They prove the conclusion they prefer by making up stuff. Then they predict results of specific actions, and if the actions lead to the predicted result, they take the assumptions as “probably true.” They didn’t prove that the assumptions are true, but they treat them as if they were true. They discard unfulfilled predictions without discarding the assumptions that these predictions were supposed to prove or disprove. Ungodly thinkers can dogmatically defend pure nonsense using these techniques.
Most ungodly thinkers assume certain necessary things like the laws of logic existing, their senses being reliable, the world around them existing, and they themselves existing. Then they assume the reliability of the laws of nature and math. They know these truths because God revealed these truths to them, but because they refuse to acknowledge God, they relegate these truths to assumption. Therefore, even though they hold some truth, they don’t know any truth. They’re always learning but never coming to knowledge of the truth. (2 Timothy 3:7) They hear God’s voice, but as they hear, they don’t hear, so faith never comes to them. (Matthew 13:13-15)
Ungodly thinking always bases reason on making up stuff and calling made-up stuff true. Unfortunately, those who choose to be ungodly have no choice but to be irrational, yet they believe that they’re being rational. They can’t be rational without knowing that the premise of their reasoning is true, and they can’t prove that a premise is true. They can only make up stuff and pretend it’s true.
