“The whole contains nothing which is not or its advantage; and all natures indeed have this common principle, but the nature of the universe has this principle besides, that it cannot be compelled even by any external cause to generate anything harmful to itself.”

A Vindication of Natural Society (1756)
Context: Kings are ambitious; the nobility haughty; and the populace tumultuous and ungovernable. Each party, however in appearance peaceable, carries on a design upon the others; and it is owing to this, that in all questions, whether concerning foreign or domestic affairs, the whole generally turns more upon some party-matter than upon the nature of the thing itself; whether such a step will diminish or augment the power of the crown, or how far the privileges of the subject are likely to be extended or restricted by it. And these questions are constantly resolved, without any consideration of the merits of the cause, merely as the parties who uphold these jarring interests may chance to prevail; and as they prevail, the balance is overset, now upon one side, now upon the other. The government is, one day, arbitrary power in a single person; another, a juggling confederacy of a few to cheat the prince and enslave the people; and the third, a frantic and unmanageable democracy. The great instrument of all these changes, and what infuses a peculiar venom into all of them, is party. It is of no consequence what the principles of any party, or what their pretensions, are; the spirit which actuates all parties is the same; the spirit of ambition, of self-interest, of oppression, and treachery. This spirit entirely reverses all the principles which a benevolent nature has erected within us; all honesty, all equal justice, and even the ties of natural society, the natural affections. In a word, my Lord, we have all seen, and, if any outward considerations were worthy the lasting concern of a wise man, we have some of us felt, such oppression from party government as no other tyranny can parallel. We behold daily the most important rights, rights upon which all the others depend, we behold these rights determined in the last resort without the least attention even to the appearance or colour of justice; we behold this without emotion, because we have grown up in the constant view of such practices; and we are not surprised to hear a man requested to be a knave and a traitor, with as much indifference as if the most ordinary favour were asked; and we hear this request refused, not because it is a most unjust and unreasonable desire, but that this worthy has already engaged his injustice to another. These and many more points I am far from spreading to their full extent. <!-- You are sensible that I do not put forth half my strength; and you cannot be at a loss for the reason. A man is allowed sufficient freedom of thought, provided he knows how to choose his subject properly. Tou may criticise freely upon the Chinese constitution, and observe with as much severity as you please upon the absurd tricks or destructive bigotry of the bonzees. But the scene is changed as you come homeward, and atheism or treason may be the names given in Britain, to what would be reason and truth if asserted of China.

"The War Universe", taped conversation, first published in Grand Street, No. 37 (1991) http://openlibrary.org/b/OL7452886M/Grand_Street_37_(Grand_Street)
Context: This is a war universe. War all the time. That is its nature. There may be other universes based on all sorts of other principles, but ours seems to be based on war and games. All games are basically hostile. Winners and losers. We see them all around us: the winners and the losers. The losers can oftentimes become winners, and the winners can very easily become losers.

“The universal nature has no external space”
VIII, 50
Meditations (c. 121–180 AD), Book VIII
Context: The universal nature has no external space; but the wondrous part of her art is that though she has circumscribed herself, everything which is within her which appears to decay and to grow old and to be useless she changes into herself, and again makes other new things from these very same, so that she requires neither substance from without nor wants a place into which she may cast that which decays. She is content then with her own space, and her own matter, and her own art.

1840s, Essays: First Series (1841), Compensation
Context: The universe is represented in every one of its particles. Every thing in nature contains all the powers of nature. Every thing is made of one hidden stuff; as the naturalist sees one type under every metamorphosis, and regards a horse as a running man, a fish as a swimming man, a bird as a flying man, a tree as a rooted man. Each new form repeats not only the main character of the type, but part for part all the details, all the aims, furtherances, hindrances, energies, and whole system of every other. Every occupation, trade, art, transaction, is a compend of the world, and a correlative of every other. Each one is an entire emblem of human life; of its good and ill, its trials, its enemies, its course and its end. And each one must somehow accommodate the whole man, and recite all his destiny.
The world globes itself in a drop of dew.
