How many foolish things we say only through the habit of speech! How many useless words we speak! If we are introduced to someone we must speak; if not we are thought impolite. Then come such conversations as, 'It is such a fine day; it is cold', or whatever the weather is, and so on; such speech without reason in time turns into a disease, so that a person cannot get on without emptying the head of others by speaking about useless things. He can no longer live one moment without it owing to his self-interest; he becomes so fond of speech that sometimes he will tell the whole story of his life to a stranger, preventing him from speaking, although that man may be very bored and would like to say, 'What do I care about all that?' And people also give out secrets that afterwards they regret having told.
