One Common Substance
Marcus Aurelius
Meditations

A vision of universal unity, arguing that despite the appearance of separate bodies and souls, there is only one common substance and one intellectual soul.

...others, I know certainly that they are, and therefore worship them. XXII. Herein doth consist happiness of life, for a man to know thoroughly the true nature of everything; what is the matter, and what is the form of it: with all his heart and soul, ever to do that which is just, and to speak the truth. What then remaineth but to enjoy thy life in a course and coherence of good actions, one upon another immediately succeeding, and never interrupted, though for never so little a while? XXIII.
There is but one light of the sun, though it be intercepted by walls and mountains, and other thousand objects. There is but one common substance of the whole world, though it be concluded and restrained into several different bodies, in number infinite. There is but one common soul, though divided into innumerable particular essences and natures. So is there but one common intellectual soul, though it seem to be divided.
And as for all other parts of those generals which we have mentioned, as either sensitive souls or subjects, these of themselves (as naturally irrational) have no common mutual reference one unto another, though many of them contain a mind, or reasonable faculty in them, whereby they are ruled and governed. But of every reasonable mind, this the particular nature, that it hath reference to whatsoever is of her own kind, and desireth to be united: neither can this common affection, or mutual uni...

One Order Through All
Marcus Aurelius
Meditations

This passage asserts the existence of a universal order and a single divine reason that governs all rational creatures through a common law and truth.

...tted together, and the knot is sacred, neither is there anything in the world, that is not kind and natural in regard of any other thing, or, that hath not some kind of reference and natural correspondence with whatsoever is in the world besides. For all things are ranked together, and by that decency of its due place and order that each particular doth observe, they all concur together to the making of one and the same κόσμος or world: as if you said, a comely piece, or an orderly composition.
For all things throughout, there is but one and the same order; and through all things, one and the same God, the same substance and the same law. There is one common reason, and one common truth, that belongs unto all reasonable creatures, for neither is there save one perfection of all creatures that are of the same kind, and partakers of the same reason.
VII. Whatsoever is material, doth soon vanish away into the common substance of the whole; and whatsoever is formal, or, whatsoever doth animate that which is material, is soon resumed into the common reason of the whole; and the fame and memory of anything, is soon swallowed up by the general age and duration of the whole. VIII. To a reasonable creature, the same action is both according to nature, and according to reason. IX. Straight of itself, not made straight. X. As several members in...

Divine Contentment's Embrace
Marcus Aurelius
Meditations

A vision of spiritual contentment achieved by trusting in divine providence and recognizing that all changes in the universe contribute to a perfect, holistic welfare.

...halt be good, simple, single, more open and visible, than that body by which it is enclosed. Thou wilt one day be sensible of their happiness, whose end is love, and their affections dead to all worldly things. Thou shalt one day be full, and in want of no external thing: not seeking pleasure from anything, either living or insensible, that this world can afford; neither wanting time for the continuation of thy pleasure, nor place and opportunity, nor the favour either of the weather or of men.
When thou shalt have content in thy present estate, and all things present shall add to thy content: when thou shalt persuade thyself, that thou hast all things; all for thy good, and all by the providence of the Gods: and of things future also shalt be as confident, that all will do well, as tending to the maintenance and preservation in some sort, of his perfect welfare and happiness, who is perfection of life, of goodness, and beauty; who begets all things, and containeth all things in himself, and in himself doth recollect all things from all places that are dissolved, that of them he may beget others again like unto them.
Such one day shall be thy disposition, that thou shalt be able, both in regard of the Gods, and in regard of men, so to fit and order thy conversation, as neither to complain of them at any time, for anything that they do; nor to do anything thyself, for which thou mayest justly be condemned. II. As one who is altogether governed by nature, let it be thy care to observe what it is that thy nature in general doth require. That done, if thou find not that thy nature, as thou art a living sensibl...

All Things Connected
Marcus Aurelius
Meditations

A reflection on the cyclical nature of time and the profound interconnectedness of all things within a unified, rational universe.

...come from one beginning; either all severally and particularly deliberated and resolved upon, by the general ruler and governor of all; or all by necessary consequence. So that the dreadful hiatus of a gaping lion, and all poison, and all hurtful things, are but (as the thorn and the mire) the necessary consequences of goodly fair things. Think not of these therefore, as things contrary to those which thou dost much honour, and respect; but consider in thy mind the true fountain of all. XXXIV
He that seeth the things that are now, hath Seen all that either was ever, or ever shall be, for all things are of one kind; and all like one unto another. Meditate often upon the connection of all things in the world; and upon the mutual relation that they have one unto another. For all things are after a sort folded and involved one within another, and by these means all agree well together. For one thing is consequent unto another, by local motion, by natural conspiration and agreement, and by substantial union, or, reduction of all substances into one.
XXXV. Fit and accommodate thyself to that estate and to those occurrences, which by the destinies have been annexed unto thee; and love those men whom thy fate it is to live with; but love them truly. An instrument, a tool, an utensil, whatsoever it be, if it be fit for the purpose it was made for, it is as it should be though he perchance that made and fitted it, be out of sight and gone. But in things natural, that power which hath framed and fitted them, is and abideth within them still: fo...

The World's One Soul
Marcus Aurelius
Meditations

A reflection on the interconnectedness of the cosmos, viewing the world as a single living substance where all events are linked by a unified soul and motion.

...which is so near it should either be cut or burnt, or suffer any corruption or putrefaction, yet let that part to which it belongs to judge of these, be still at rest; that is, let her judge this, that whatsoever it is, that equally may happen to a wicked man, and to a good man, is neither good nor evil. For that which happens equally to him that lives according to nature, and to him that doth not, is neither according to nature, nor against it; and by consequent, neither good nor bad. XXXIII.
Ever consider and think upon the world as being but one living substance, and having but one soul, and how all things in the world, are terminated into one sensitive power; and are done by one general motion as it were, and deliberation of that one soul; and how all things that are, concur in the cause of one another's being, and by what manner of connection and concatenation all things happen.
XXXIV. What art thou, that better and divine part excepted, but as Epictetus said well, a wretched soul, appointed to carry a carcass up and down? XXXV. To suffer change can be no hurt; as no benefit it is, by change to attain to being. The age and time of the world is as it were a flood and swift current, consisting of the things that are brought to pass in the world. For as soon as anything hath appeared, and is passed away, another succeeds, and that also will presently out of sight. XXXV...
