Observe, I only wish you to distinguish these things in your own minds; I would by no means advise you to discontinue the laudable practice of confounding them perpetually in speaking to others. When you have nearly exhausted human patience in explaining, justifying, vindicating; when, in spite of all the pains you have taken, you have more than half betrayed your own vanity; you have a never-failing resource, in paying tribute to that of your opponent, as thus:-- “I am sure you must be sensible that I should never take so much pains to justify myself if I were indifferent to your opinion.--I know that I ought not to disturb myself with such trifles; but nothing is a trifle to me which concerns you. I confess I am too anxious to please; I know it’s a fault, but I cannot cure myself of it now.--Too quick sensibility, I am conscious, is the defect of my disposition; it would be happier for me if I could be more indifferent, I know.” Who could be so brutal as to blame so amiable, so candid a creature? Who would not submit to be tormented with kindness? When once your captive condescends to be flattered by such arguments as these, your power is fixed; your future triumphs can be bounded only by your own moderation; they are at once secured and justified. Forbear not, then, happy pupils; but, arrived at the summit of power, give a full scope to your genius, nor trust to genius alone: to exercise in all its extent your privileged dominion, you must acquire, or rather you must pretend to have acquired, infallible skill in the noble art of physiognomy; immediately the thoughts as well as the words of your subjects are exposed to your inquisition. Words may flatter you, but the countenance never can deceive you; the eyes are the windows of the soul, and through them you are to watch what passes in the inmost recesses of the heart. There, if you discern the slightest ideas of doubt, blame, or displeasure; if you discover the slightest symptoms of revolt, take the alarm instantly. Conquerors must maintain their conquests; and how easily can they do this, who hold a secret correspondence with the minds of the vanquished! Be your own spies then; from the looks, gestures, slightest motions of your enemies, you are to form an alphabet, a language intelligible only to yourselves, yet by which you shall condemn them; always remembering that in sound policy suspicion justifies punishment. In vain, when you accuse your friends of the high treason of blaming you, in vain let them plead their innocence, even of the intention. “They did not say a word which could be tortured into such a meaning.” No, “but they looked daggers, though they used none.” And of this you are to be the sole judge, though there were fifty witnesses to the contrary.
