"Speak but little, and that little only when thy own purposes require it. Heaven has given thee two ears but only one tongue, which means: listen to two things, but be not the first to propose one."

An empirical philosophy is in any case a kind of intellectual disrobing. We cannot permanently divest ourselves of the intellectual habits we take on and wear when we assimilate the culture of our own time and place. But intelligent furthering of culture demands that we take some of them off, that we inspect them critically to see what they are made of and what wearing them does to us. We cannot achieve recovery of primitive naïveté. But there is attainable a cultivated naïveté of eye, ear and thought.
