An open mind is all very well in its way, but it ought not to be so open that there is no keeping anything in or out of it.

Context

“I do not mind lying, but I hate inaccuracy. v A friend who cannot at a pinch remember a thing or two that never happened is as bad as one who does not know how to forget. vi Cursed is he that does not know when to shut his mind. An open mind is all very well in its way, but it ought not to be so open that there is no keeping anything in or out of it. It should be capable of shutting its doors sometimes, or it may be found a little draughty. vii He who knows not how to wink knows not how to see; and he who knows not how to lie knows not how to speak the truth.” source
