CONSIDER, you who are going to take your trial, what you wish to preserve, and in what to succeed. For if you wish to preserve a choice conformable to nature, you are resting safe; everything goes well; you have no trouble on your hands. While you wish to preserve what is in your own power, and which is naturally free, and are contented with that, whom have you longer to care for? For who is the master of things like these? Who can take them away.''If you wish to be a man of honour and fidelity, who shall prevent you? If you wish not to be restrained or compelled, who shall compel you to desires contrary to your principles; to aversions contrary to your opinion? The judge, perhaps, will pass a sentence against you which he thinks formidable: but how can he likewise make you receive it with aversion? Since, then, desire and aversion are in your own power, what have you else to care for? Let this be your introduction, this your narration, this your proof, this your victory, this your conclusion, and this your applause.
