When you lay down a proposition which is forthwith controverted, it is of course optional with you to take up the cudgels in its defence. If you are deeply convinced of its truth, you will perhaps be content to leave it to take care of itself; or, at all events, you will not go out of your way to push its fortunes; for you will reflect that in the long run an opinion often borrows credit from the forbearance of its patrons. In the long run, we say; it will meanwhile cost you an occasional pang to see your cherished theory turned into a football by the critics. A football is not, as such, a very respectable object, and the more numerous the players, the more ridiculous it becomes. Unless, therefore, you are very confident of your ability to rescue it from the chaos of kicks, you will best consult its interests by not mingling in the game.
