“It is not as though "Do what thou wilt shall be the whole of the law" was a precept from which splendid fiction could not be drawn; it is rather that what these small-time rebels choose to do is so trivial, so cheap, and in the end, so dreary.”

Golden Sayings of Epictetus
Context: Canst thou judge men?... then make us imitators of thyself, as Socrates did. Do this, do not do that, else will I cast thee into prison; this is not governing men like reasonable creatures. Say rather, As God hath ordained, so do; else thou wilt suffer chastisement and loss. Askest thou what loss? None other than this: To have left undone what thou shouldst have done: to have lost the faithfulness, the reverence, the modesty that is in thee! Greater loss than this seek not to find! (91).

The Comment; this is a summary combination and restatement of the assertions of I:40 and I:57.

Conversation at Turin, as quoted in Memoirs of Count Miot de Melito (1788 - 1815) as translated by Frances Cashel Hoey and John Lillie (1881), Vol. II, p. 113
'Monk' refers to George Monck, military ruler of Puritan England after Cromwell, who ultimately gave up power when he invited Charles II in and enabled the English Restoration
Context: I do not care to play the part of Monk; I will not play it myself, and I do not choose that others shall do so. But those Paris lawyers who have got into the Directory understand nothing of government. They are poor creatures. I am going to see what they want to do at Rastadt; but I doubt much that we shall understand each other, or long agree together. They are jealous of me, I know, and notwithstanding all their flattery, I am not their dupe; they fear more than they love me. They were in a great hurry to make me General of the army of England, so that they might get me out of Italy, where I am the master, and am more of a sovereign than commander of an army. They will see how things go on when I am not there. I am leaving Berthier, but he is not fit for the chief command, and, I predict, will only make blunders. As for myself, my dear Miot, I may inform you, I can no longer obey; I have tasted command, and I cannot give it up. I have made up my mind, if I cannot be master I shall leave France; I do not choose to have done so much for her and then hand her over to lawyers.
