Come, let us reason together. — Isaiah
It is true that whatever negates, opposes, or destroys rationality or logic is evil. Ayn Rand said that Reason is the faculty by which man must live. Christians live by faith. John Galt said,
Do not say that you’re afraid to trust your mind because you know so little. Are you safer in surrendering to mystics and discarding the little you do know? Live and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hock-shops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience—that your mind is fallible by becoming mindless will not make you infallible—that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error. (For the New Intellectual p. 178, Atlas Shrugged p. 982)
It’s true that Christians are exhorted to “walk by faith and not by sight.” But the context of this passage does not obviate the need for anyone to abandon their God-given faculty of reason in order to take up faith. As a speed boat navigates through the waterways in the bay and a moped circumvents the narrow streets of the village, so reason and faith are vehicles to navigate different aspects of reality.
Do you see more harmony or dissonance between Faith and Reason?
