Love is the wisdom of the fool and the folly of the wise. - Samuel Johnson

"Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it."

"There is nothing, Sir, too little for so little a creature as man. It is by studying little things that we attain the great art of having as little misery and as much happiness as possible."

"Love is the wisdom of the fool and the folly of the wise."

"What we hope ever to do with ease, we must learn first to do with diligence."

"Life affords no higher pleasure than that of surmounting difficulties, passing from one step of success to another, forming new wishes and seeing them gratified."
