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 want 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.
