Nobody is publicly accepted as an expert on poetry unless he displays the sign of poet, mathematician, etc., but universal men want no sign and make hardly any distinction between the crafts of poet and embroiderer. Universal men are not called poets or mathematicians, etc. But they are all these things and judges of them too. No one could guess what they are, and they will talk about whatever was being talked about when they came in. One quality is not more noticeable in them than another, unless it becomes necessary to put it into practice, and then we remember it.
Blaise Pascal
