Have a Touch of the Trader.

Have a Touch of the Trader. Life should not be all thought: there should be action as well. Very wise folk are generally easily deceived, for while they know out-of-the-way things they do not know the ordinary things of life, which are much more needful. The observation of higher things leaves them no time for things close at hand. Since they know not the very first thing they should know, and what everybody knows so well, they are either considered or thought ignorant by the superficial multitude. Let therefore the prudent take care to have something of the trader about him–enough to prevent him being deceived and so laughed at, Be a man adapted to the daily round, which if not the highest is the most necessary thing in life. Of what use is knowledge if it is not practical, and to know how to live is nowadays the true knowledge.
