Letters 15.7

You need not scorn voice-culture; but I forbid you to practise raising and lowering your voice by scales and specific intonations. What if you should next propose to take lessons in walking! If you consult the sort of person whom starvation has taught new tricks, you will have someone to regulate your steps, watch every mouthful as you eat, and go to such lengths as you yourself, by enduring him and believing in him, have encouraged his effrontery to go. “What, then?” you will ask; “is my voice to begin at the outset with shouting and straining the lungs to the utmost?” No; the natural thing is that it be aroused to such a pitch by easy stages, just as persons who are wrangling begin with ordinary conversational tones and then pass to shouting at the top of their lungs. No speaker cries “Help me, citizens!” at the outset of his speech.
