When the water of a place is bad it is safest to drink none that has not been filtered through either the berry of a grape, or else a tub of malt. These are the most reliable filters yet invented. – Samuel Butler
The best man is like water. Water is good; it benefits all things and does not compete with them. It dwells in lowly places that all disdain. This is why it is so near to Tao. – Lao-Tzu
