Discourses: Book 2 1 : 5
That is why I say over and over again, "Practise these things and have them ready at hand, that is, the knowledge of what you ought to face with confidence, and what you ought to face with caution—that you ought to face with confidence that which is outside the province of the moral purpose, with caution that which is within the province of the moral purpose."—But have I not read to you, and do you not know what I am doing?—What have you been engaged upon? Trifling phrases! Keep your trifling phrases! Show me rather how you stand in regard to desire and aversion, whether you do not fail to get what you wish, or do not fall into what you do not wish. As for those trifling periods of yours, if you are wise, you will take them away somewhere and blot them out.—What then? Did not Socrates write?—Yes, who wrote as much as he? But how? Since he could not have always at hand someone to test his judgements, or to be tested by him in turn, he was in the habit of testing and examining himself, and was always in a practical way trying out some particular primary conception. That is what a philosopher writes; but trifling phrases, and "said he," "said I" he leaves to others, to the stupid or the blessed, those who by virtue of their tranquillity live at leisure, or those who by virtue of their folly take no account of logical conclusions.
