Well, what do you know? It’s a surprisingly tricky question to answer. You could list a bunch of indisputable facts, except that even things like Grass is Green raises questions of what constitutes Grass and whether the brown grass of summer is really green. 1+1=2 is another obvious answer, but even defining ‘1’ isn’t as easy as you might think.
We send children to school in the expectation that they will know more at 16 than they did at 5, but most would agree that Thomas Gradgrind’s Facts and nothing but Facts approach (Dickens’ Hard Times) is inadequate.
Knowledge comes in different forms: Facts (things we can know are true) is one; how to use Facts (we might call it Wisdom) is another; but what about knowing a person? That’s quite different; and there is knowledge that human ingenuity, wisdom, experience, and learning cannot discover, and this is where God’s revelation comes to us. Ultimately, it’s about God wanting us to know Him. As Jesus said, “Now, this is eternal life: that they know you, the only true God, and Jesus Christ.” John 17:3.
So, maybe I began with the wrong question. Not What do you know? but Who do you know?
