Sec. XX. Now one kind of caution against his snares is to know and ever remember that, whereas the soul contains true and noble and reasoning elements, as also unreasoning and false and emotional ones, the friend is always a counsellor and adviser to the better instincts of the soul, as the physician improves and maintains health, whereas the flatterer works upon the emotional and unreasoning ones, and tickles and titillates them and seduces them from reason, employing sensuality as his bait. As then there are some kinds of food which neither benefit the blood or spirit, nor brace up the nerves and marrow, but stir the passions, excite the lower nature, and make the flesh unsound and rotten, so the language of the flatterer adds nothing to soberness and reason, but encourages some love passion, or stirs up foolish rage, or incites to envy, or produces the empty and burdensome vanity of pride, or joins in bewailing woes, or ever by his calumnies and hints makes malignity and illiberality and suspicion sharp and timid and jealous, and cannot fail to be detected by those that closely observe him. For he is ever anchoring himself upon some passion, and fattening it, and, like a bubo, fastens himself on some unsound and inflamed parts of the soul. Are you angry? Have your revenge, says he. Do you desire anything? Get it. Are you afraid? Let us flee. Do you suspect? Entertain no doubts about it. But if he is difficult to detect in thus playing upon our passions, since they often overthrow reason by their intensity and strength, he will give a handle to find him out in smaller matters, being consistent in them too. For if anyone feels a little uneasy after a surfeit or excess in drink, and so is a little particular about his food and doubts the advisability of taking a bath, a friend will try and check him from excess, and bid him be careful and not indulge, whereas the flatterer will drag him to the bath, bid him serve up some fresh food, and not starve himself and so injure his constitution. And if he see him reluctant about a journey or voyage or some business or other, he will say that there is no hurry, that it's all one whether the business be put off, or somebody else despatched to look after it. And if you have promised to lend or give some money to a friend, but have repented of your offer, and yet feel ashamed not to keep your promise, the flatterer will throw his influence into the worse scale, he will confirm your desire to save your purse, he will destroy your reluctance, and will bid you be careful as having many expenses, and others to think about besides that person. And so, unless we are entirely ignorant of our desires, our shamelessness, and our timidity, the flatterer cannot easily escape our detection. For he is ever the advocate of those passions, and outspoken when we desire to repress them.[425] But so much for this matter.
