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.

Context

“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. So he who cannot suppress his opinions cannot express them. viii There can no more be a true statement without falsehood distributed through it, than a note on a well-tuned piano that is not intentionally and deliberately put out of tune to some extent in order to have the piano in the most perfect possible tune.” source
