“If the world is an aggregate of relatively independent regions, then any assumption of universal laws is false and a demand for universal norms tyrannical: only brute force (or seductive deception) can then bend the different moralities so that they fit the prescriptions of a single ethical system. And indeed, the idea of universal laws of nature and society arose in connection with a life-and-death battle: the battle that gave Zeus the power over the Titans and all other gods and thus turned his laws into the laws of the universe.”

Ten Sermons of Religion (1853), III : Of Justice and the Conscience https://en.wikisource.org/wiki/Ten_Sermons_of_Religion/Of_Justice_and_the_Conscience
Context: Justice is the constitution or fundamental law of the moral universe, the law of right, a rule of conduct for man in all his moral relations. Accordingly all human affairs must be subject to that as the law paramount; what is right agrees therewith and stands, what is wrong conflicts and falls. Private cohesions of self-love, of friendship, or of patriotism, must all be subordinate to this universal gravitation towards the eternal right.

Literary and Historical Miscellanies (1855), The Necessity, the Reality, and the Promise of the Progress of the Human Race (1854)
Context: The unchanging character of law is the only basis on which continuous action can rest. Without it man would be but as the traveller over endless morasses; the builder on quicksands; the mariner without compass or rudder, driven successively whithersoever changing winds may blow. The universe is the reflex and image of its Creator. "The true work of art," says Michael Angelo, "is but a shadow of the Divine perfections." We may say in a more general manner, that Beauty Itself Is But The Sensible Image Of The Infinite; that all creation is a manifestation of the Almighty; not the result of caprice, but the glorious display of his perfection; and as the universe thus produced, is always in the course of change, so its regulating mind is a living Providence, perpetually exerting itself anew. If his designs could be thwarted, we should lose the great evidence of his unity, as well as the anchor of our own hope.
Harmony is the characteristic of the intellectual system of the universe; and immutable laws of moral existence must pervade all time and all space, all ages and all worlds.

Outline of the Doctrine of Knowledge (1810)
Context: There is but One Principle that proceeds from God; and thus, in consequence of the unity of the Power, it is possible for each Individual to schematise his World of Sense in accordance with the law of that original harmony; — and every Individual, under the condition of being found on the way towards the recognition of the Imperative, must so schematise it. I might say: — Every Individual can and must, under the given condition, construct the True World of Sense, — for this indeed has beyond the universal and formal laws above deduced, no other Truth and Reality than this universal harmony.

Groundwork of the Metaphysics of Morals (1785)
Context: Morality is thus the relation of actions to the autonomy of the will, that is, to a possible giving of universal law through its maxims. An action that can coexist with the autonomy of the will is permitted; one that does not accord with it is forbidden. A will whose maxims necessarily harmonize with the laws of autonomy is a holy, absolutely good will. The dependence upon the principle of autonomy of a will that is not absolutely good (moral necessitation) is obligation. This, accordingly, cannot be attributed to a holy being. The objective of an action from obligation is called duty.
