 Usage: -- Base, Vile, Mean. These words, as expressing moral qualities, are here arranged in the order of their strength, the strongest being placed first. Base marks a high degree of moral turpitude; vile and mean denote, in different degrees, the lack of what is valuable or worthy of esteem.  What is base excites our abhorrence; what is vile provokes our disgust or indignation; what is mean awakens contempt.  Base is opposed to high-minded; vile, to noble; mean, to liberal or generous. Ingratitude is base; sycophancy is vile; undue compliances are mean.
