“There is often times,” says Dean Young, (father of the poet) “a prodigious distance betwixt a man's head and his heart; such a distance that they seem not to have any correspondence; not to belong to the same person, not to converse in the same world. Our heads are sometimes in Heaven, contemplating the nature of God, the blessedness of Saints, the state of eternity; while our hearts are held captive below in a conversation earthly, sensual, devilish. 'Tis possible we may sometimes commend virtue convincingly, unanswerably; and yet our own hearts be never affected by our own arguments; we may represent vice in her native dress of horror, and yet our hearts be not at all startled with their own menaces: We may study and acquaint ourselves with all the truths of religion, and yet all this out of curiosity, or hypocrisy, or ostentation; not out of the power of godliness, or the serious purpose of good living. All which is a sufficient proof that the consent of the Head and of the Heart are two different things.” Dean Young may seem in this passage to have answered Adam the Lexicographist's query in the affirmative, by shewing that the head belongs sometimes to one Self and the heart to the other. Yet these two Selves, notwithstanding this continual discord, are so united in matrimony, and so inseparably made one flesh, that it becomes another query whether death itself can part them. The aforesaid Dean concludes one of his Discourses with the advice of an honest heathen. _Learn to be one Man_; that is, learn to live and act alike. For says he, “while we act from contrary principles; sometimes give, and sometimes defraud; sometimes love and sometimes betray; sometimes are devout, and sometimes careless of God; this is to be _two_ Men, which is a foolish aim, and always ends in loss of pains. ‘No,’ says wise Epictetus, ‘_Learn to be one Man_,’ thou mayest be a good man; or thou mayest be a bad man, and that to the purpose; but it is impossible that thou shouldst be both. And here the Philosopher had the happiness to fall in exactly with the notion of my text. _We cannot serve two Masters._”
