The view of faith as the antipathy of reason can get you into a lot of trouble if you actually put such a view into practice. Been there, seen it, done it, got the T-shirt.
Reason and faith should be viewed as complementary, not contradictory. Hebrews 11:1 tells us that faith is the evidence of what we do not see. It does not tell us that faith is the denial of what we do see. That is lying.
Faith is being prepared to take action when you have insufficient evidence but only someone’s word to go on. But you still need to verify the integrity of the evidence that you do have, and that is what reason is all about.
Venture capitalists and investors apply this principle all the time. Just watch any episode of Dragon’s Den. Investing tens or hundreds of thousands of pounds in a startup is ultimately a step of faith, but if they didn’t apply reason before taking that step of faith, they would end up investing in people who don’t know what a balance sheet is, trying to break into an already saturated market with vapourware.
When you start viewing reason and faith as enemies, rather than as complementary to each other, it’s all too easy to end up getting into complete unreality or making things up. I’ve seen people buy into that line who ended up considering it perfectly acceptable to make demonstrably untrue claims about material facts, completely losing track of the fact that doing such a thing is lying. I think that the thirteen or so LSDYECs who have tried to convince me that Deuteronomy 25:13-16 does not apply to science most likely all fall into that category. And don’t get me started on the way they end up falling hook, line and sinker for every tinfoil hat conspiracy theory that’s out there…
