Two Kinds of Moralists.—To see a law of nature for the first time, and to see it whole (for example, the law of gravity or the reflection of light and sound), and afterwards to explain such a law, are two different things and concern different classes of minds. In the same way, those moralists who observe and exhibit human laws and habits—moralists with discriminating ears, noses, and eyes—differ entirely from those who interpret their observations. These latter must above all be inventive, and [pg 313] must possess an imagination untrammelled by sagacity and knowledge.
