Sense never fails to give them that have it, Words enough to make them understood. It too often happens in some conversations, as in Apothecary Shops, that those Pots that are Empty, or have Things of small Value in them, are as gaudily Dress'd as those that are full of precious Drugs. They that soar too high, often fall hard, making a low and level Dwelling preferable. The tallest Trees are most in the Power of the Winds, and Ambitious Men of the Blasts of Fortune. Buildings have need of a good Foundation, that lie so much exposed to the Weather.
