Not only do I not know what's going on, but I wouldn't know what to do about it if I did.

Stupid headache is back and Ibuprofen isn't fixing it.
The current working theory (thanks, John Nuiver) is that my left cleat popped out of the pedal while I was up out of the saddle pushing down hard on that pedal. As a result I went down on my left side, my hip hit first and my head bounced off the pavement hard enough to knock me out and cause a concussion. That explanation works.
The bike store is out of the correct cleat for my shoes but will have them in early next week. And I won't be riding by then anyway. I had planned to be back at the gym this afternoon but promised myself that would only happen if the headache was gone.
Double-drat!

Car Talk is ceasing production in October. The world is coming to an end, and not because the Mayans said so.
I don't care if Tom is turning 75. Saturday morning wrenching in the garage won't work without Click and Clack playing on the radio. I'm apt to put the muffler bearings in backwards without their sage advice.

After using the wire brush attachment on my drill I primed the Rambler's wheels in preparation for painting them tomorrow. The can says to apply several light coats. How often? It says that assuming 70 degrees and 50% humidity, a subsequent coat should be applied within the hour or after 24 hours. How about 104 degree heat and 9% humidity?

Cornelius Van Til was a Dutch theologian who spent time in the U.S., including at Calvin Seminary in Grand Rapids, our home up until 5 years ago. He was a braniac and reading his stuff will give even a non-cyclist a headache. One of his great contributions to recent theological thought (he died in 1987) is the concept of presuppositional apologetics. That's not nearly as complicated as it sounds; scientists and theologians are required to come up with polysyllabic terminology when plain words will do the job.

Presuppositional apologetics says that Christianity cannot and should not try to make a case (that's called apologetics) for the core beliefs of our faith. We presuppose them. We accept them going in. So any discussion with a skeptic begins with the Christian openly presupposing certain truths rather than trying to establish them with empirical evidence the field of science requires. That drives the skeptic, especially the modern skeptic with his dependence on the scientific method, absolutely bonkers. "You can't do that!" Yes, I can and have. I openly confess (homologeo) that Christianity is a faith, its basic premises are beyond empirical verification, and I'm fine with that. ("I am not ashamed of the gospel of God....")

This is not an unreasonable faith. It does not require the suspension of my mental faculties. In fact, in many cases (not all) it provides a better explanation for the physical universe than the scientific method. That's very different from saying I must find a way to align the empirical evidence with the tenets of my faith. Furthermore, there are several very important issues the scientific method is incapable of addressing. Consistent with its ground rules it completely avoids these issues, like the presence/absence of a God, what happens after death, and matters of morality. Bring these up and the empiricist shrugs his shoulders and says, "I don't know and can't go there. I work with demostrable evidence." That's fine; he/she has chosen that playing field. But it is no more naive of me to accept matters I cannot prove than it is of him to ignore matters he cannot address empirically.

In our contemporary cultural environment there is the tendency to look on those of us who take a presuppositional apologetic view of things as though we were well intentioned but slightly simple folk. So long as we stay in our corner and don't get in the way of the more enlightened and intellectual people we're tolerated. Just keep our views to ourselves and out of the public discussion.

Sorry, can't go there. And I can't because I care about people - people who hurt, who hurt each other, who die, and who stand at the bedside of those who die, who are told they have cancer or that their spouse is leaving them for another. They don't care about fossils and sedimentary layers and the half life of a radioactive element. They need the answers only presuppositional apologetics, only biblical faith can provide.

In conclusion, I can end this post with no better than this picture our oldest son posted to his Facebook account this morning. T'ank you, Fadder, for this blessing!
