We never excuse the absolute want of spirit and dignity of character, or a proper sense of what is due to one's self, in society and the common intercourse of life.

Context

“To enter thoroughly into this method of thinking, we must make allowance for the ancient maxims, that no one ought to prolong his life after it became dishonourable; but, as he had always a right to dispose of it, it then became a duty to part with it.] We never excuse the absolute want of spirit and dignity of character, or a proper sense of what is due to one's self, in society and the common intercourse of life. This vice constitutes what we properly call MEANNESS; when a man can submit to the basest slavery, in order to gain his ends; fawn upon those who abuse him; and degrade himself by intimacies and familiarities with undeserving inferiors.” source
