Coronavirus shows us it’s time to rethink everything.

I imagine mentioning William Shakespeare not to know what an arthropod is, or a vertebrate, or to be unable to explain the difference between an insect and spider. No one is embarrassed when a “well-educated” person cannot provide even a rough explanation of the greenhouse effect, the carbon cycle or the water cycle, or of how soils form.

All this is knowledge as basic as being aware that Shakespeare was a playwright. Yet ignorance of such earthy matters sometimes seems to be worn as a badge of sophistication. I love Shakespeare, and I believe the world would be a poorer and a sadder place without him. But we would survive. The issues about which most people live in ignorance are, by contrast, matters of life and death.
