“The wise man through an excess of wisdom is made a fool.”
“Love is the wisdom of the fool and the folly of the wise.”
“Only a silly sober fool could think it; imagine gloating over such nonsense (because in one sense the drinker learns wisdom, in the words of Goethe or Blake or whichever it was "the pathway to wisdom lies through excess")”
“Wine turns the wise man into a fool and the fool into a wise man.”
“Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.”
“The fool doth think he is wise, but the wise man knows himself to be a fool.”
