Closed-Minded, adj. Possessing a mind which, like a pipe sealed on
both ends, does not permit ideas to enter and leave. Contrasted with
an open mind, which permits ideas to flow, like water through a pipe,
entering and exiting without leaving any trace. There is perhaps a
third prospect, of weighing and examining most ideas against a higher
standard to grab firm hold of what is meritorious and worth keeping
and reject what is twisted and mistaken, but this idea does not occur
sufficiently often to merit its own word. Promoting open-mindedness is
perhaps the single greatest achievement of current thought.
If Jesus Christ were to come today, people would not crucify him.
They would ask him to dinner, and hear what he had to say, and make
fun of it.
