“Valour’s the best reward; ‘tis valour that surpasses all things else : our liberty, our safety, life, estate, our parents, children, country, are by this preserved, protected : valour everything comprises in itself; and every good awaits the man who is possess’d of valour. (translator Thornton)”
Amphitryon, Act II, scene 2, line 16.
Variant translation: Courage is the very best gift of all; courage stands before everything, it does, it does! It is what maintains and preserves our liberty, safety, life, and our homes and parents, our country and children. Courage comprises all things: a man with courage has every blessing.
Amphitryon

Addresses to the Virginia Ratifying Convention (1788)
Context: No man has a greater regard for the military gentlemen than I have. I admire their intrepidity, perseverance, and valour. But when once a standing army is established, in any country, the people lose their liberty. When against a regular and disciplined army, yeomanry are the only defence — yeomanry, unskillful & unarmed, what chance is there for preserving freedom? Give me leave to recur to the page of history, to warn you of your present danger. Recollect the history of most nations of the world. What havock, desolation, and destruction, have been perpetrated by standing armies? An instance within the memory of some of this house, — will shew us how our militia may be destroyed. Forty years ago, when the resolution of enslaving America was formed in Great Britain, the British parliament was advised by an artful man, [Sir William Keith] who was governor of Pennsylvania, to disarm the people. That it was the best and most effectual way to enslave them. But that they should not do it openly; but to weaken them and let them sink gradually, by totally difusing and neglecting the militia. [Here MR. MASON quoted sundry passages to this effect. ] This was a most iniquitous project. Why should we not provide against the danger of having our militia, our real and natural strength, destroyed?

“After this, having invited over to him all persons whatsoever that were famous for valour in foreign nations, he began to augment the number of his domestics, and introduced such politeness into his court, as people of the remotest countries thought worthy of their imitation. So that there was not a nobleman who thought himself of any consideration, unless his clothes and arms were made in the same fashion as those of Arthur's knights.”
Tunc invitatis probissimis quibusque ex longe positis regnis, cepit familiam suam augmentare, tantamque facetiam in domo sua habere ita et emulationem longe manentibus populis ingereret. Unde nobilissimus quisque incitatus nichili pendebat se nisi sese sive in induendo sive in arma ferendo ad modo militum Arturi haberet.
