It is that deceitful part in man, that mistress of error and falsity, the more deceptive that she is not always so; for she would be an infallible rule of truth, if she were an infallible rule of falsehood. But being most generally false, she gives no sign of her nature, impressing the same character on the true and the false.
I do not speak of fools, I speak of the wisest men; and it is among them that the imagination has the great gift of persuasion. Reason protests in vain; it cannot set a true value on things.
This arrogant power, the enemy of reason, who likes to rule and dominate it, has established in man a second nature to show how all-powerful she is. She makes men happy and sad, healthy and sick, rich and poor; she compels reason to believe, doubt, and deny; she blunts the senses, or quickens them; she has her fools and sages; and nothing vexes us more than to see that she fills her devotees with a satisfaction far more full and entire than does reason. Those who have a lively imagination are a great deal more pleased with themselves than the wise can reasonably be. They look down upon men with haughtiness; they argue with boldness and confidence, others with fear and diffidence; and this gaiety of countenance often gives them the advantage in the opinion of the hearers, such favour have the imaginary wise in the eyes of judges of like nature. Imagination cannot make fools wise; but she can make them happy, to the envy of reason which can only make its friends miserable; the one covers them with glory, the other with shame.
What but this faculty of imagination dispenses reputation,[Pg 25] awards respect and veneration to persons, works, laws, and the great? How insufficient are all the riches of the earth without her consent!
Would you not say that this magistrate, whose venerable age commands the respect of a whole people, is governed by pure and lofty reason, and that he judges causes according to their true nature without considering those mere trifles which only affect the imagination of the weak? See him go to sermon, full of devout zeal, strengthening his reason with the ardour of his love. He is ready to listen with exemplary respect. Let the preacher appear, and let nature have given him a hoarse voice or a comical cast of countenance, or let his barber have given him a bad shave, or let by chance his dress be more dirtied than usual, then however great the truths he announces. I wager our senator loses his gravity.
If the greatest philosopher in the world find himself upon a plank wider than actually necessary, but hanging over a precipice, his imagination will prevail, though his reason convince him of his safety.[49] Many cannot bear the thought without a cold sweat. I will not state all its effects.
Every one knows that the sight of cats or rats, the crushing of a coal, etc. may unhinge the reason. The tone of voice affects the wisest, and changes the force of a discourse or a poem.
Love or hate alters the aspect of justice. How much greater confidence has an advocate, retained with a large fee, in the justice of his cause! How much better does his bold manner make his case appear to the judges, deceived as they are by appearances! How ludicrous is reason, blown with a breath in every direction!
I should have to enumerate almost every action of men who scarce waver save under her assaults. For reason has been obliged to yield, and the wisest reason takes as her own principles those which the imagination of man has everywhere rashly introduced. [He who would follow reason only would be deemed foolish by the generality of men. We must judge by the opinion of the majority of mankind. Because it has pleased them, we must work all day for pleasures seen to be imaginary; and after sleep has refreshed our tired reason, we must forthwith start up and rush after phantoms, and suffer the impressions of this mistress of the world.
