A lot of the questions that show up here are about trying to break open some or other old idea that seems unfounded and trying to 'explain' it in terms of something else that is also unfounded, but perhaps feels more satisfying. In culture, there is the tendency to explain a lot of unknowable things with ideas about God. But it all just seems like question-begging, and frankly, I feel just as hungry (or not) afterwards.
What is it that drives people to come up with yet more and more explanations that are not actually founded on anything? What stops us from just admitting, "That's all the farther" and moving on to something useful?
When I started learning about computer programming about 45 years ago, it came after some learning about electronics. So I can say that I do understand transistors, gates, CPUs, memory, network communications, databases and so on. As I write software now, I know 'enough' about the mechanics of computers and systems that I feel no need to pry in to quantum electrodynamics or string theory when I write a web application. I am satisfied about the foundation I am building on.
But some people apparently feel a terrifying gulf underneath their existence and are frantically churning out bricks and mortar to construct something to hold their lives up. Why? It's not going anywhere. Why this angst?
