Thomas Aquinas

It is annoying to a man to not realize what he desires, and so he shows the anxiety which he suffered in silence by a comparison saying, "Behold my womb," my mind, "is like must," which ferments, and "without a vent breaks new casks." For unless the gas caused by fermenting new wine escapes in some opening, the gas is so increased inside that it sometimes breaks the casks.
