Kant's 1795 'Toward Perpetual Peace' — republican constitutions, a federation of free states, cosmopolitan right

Published in 1795 in the aftermath of the Treaty of Basel (5 April 1795) between Prussia and revolutionary France, 'Zum ewigen Frieden: Ein philosophischer Entwurf' lays out Kant's political-philosophical programme for perpetual peace. The essay's distinctive form mimics an international treaty: preliminary articles (no standing armies, no national debt for war, no interference in another state's constitution, no acts that would render mutual confidence impossible in future peace — assassinations, breach of capitulation, instigation of treason); definitive articles (every state must have a republican constitution; the law of nations must rest on a federation of free states; cosmopolitan right is restricted to the conditions of universal hospitality); two supplements (on the guarantee of perpetual peace, on the secret article); and an Appendix on the relation between politics and morality. Kant's central claim is that a federation of republics, where citizens bear the costs of war and must consent to it, is the only stable basis for international peace; and that history exhibits a teleological-providential 'guarantee' that, through commerce, communication, and the failure of war, will tend toward republican federation. The essay inaugurates modern philosophy of international law and underwrites both the League of Nations (Wilson invoked it) and the United Nations Charter. The third definitive article — cosmopolitan right as universal hospitality — anticipates contemporary refugee-protection thinking and the entire human-rights framework.

Internal Tensions

Founding document of modern philosophy of international law and cosmopolitan politics. Read by Wilson and the framers of the League of Nations Covenant; cited by the UN Charter's preamble; foundational for the contemporary cosmopolitan-democratic-peace theory (Doyle, Russett); contested by realist political theory (Morgenthau) as utopian. The third definitive article on cosmopolitan right is the philosophical-historical seed of the post-1948 human-rights framework.

Do you really choose? The future is open and you are a genuine origin of it. 69% Are addicts responsible for their addiction? The addict could have chosen otherwise — that's why recovery is real. 69% Should we hold AI systems responsible for what they do? An AI without a free will is not the kind of thing that can be responsible. 69% Is the universe running out of usable energy? Time is unbounded but matter is finite; usable energy can fail without time failing. 47% Are natural resources fundamentally finite, or only practically so? Time goes on but matter is bounded; we are eventually constrained even with infinite time. 47% Could we owe future generations more than is materially possible to provide? Time is unbounded but matter is not; we can owe more across long time than the matter can provide. 47% How much weight do future people deserve? Time arises from events or from a deeper substrate — the future is not yet. 32% Is regret rational? The past is not a thing now; regret is the present holding what is no longer. 32% Do we owe extinct species something we cannot give them?

What is money?
The question of what money is — a measured store of real value, an agreed-on practice, a relational ledger of debts, or just a name we apply to many different things — sits behind every argument about inflation, cryptocurrency, debt, and the state.
Money is a social practice — its content is what we make it.
On this view, money is exactly what societies do that performs the monetary functions. There is no fact about whether something is 'really' money beyond whether it is used as money. A community that decides shell beads or carbon credits or proof-of-work hashes count as …

What is a nation?
Whether a nation is a real moral community with intrinsic character, a constructed legal-political artifact, a web of kinship and shared history, an imagined community, or a conventional partition of a deeper unity — these are real ontological positions with sharply different political downstream.
A nation is a constructed polity — a project, not a discovery.
On this view, nations are made: by treaties, by wars, by deliberate institution-building, by the slow work of collective practice. There is nothing intrinsic about a national kind; what exists is the practice. What we owe the nation is what we owe any institution we …

What makes someone male or female?
Whether sex is a real biological kind, a constructed social category, a relational identity, a label applied to varied phenomena, or a conventional distinction within a deeper unity is the ontological question the contemporary dispute about gender is mostly about.
Gender is constructed; what counts as male or female reflects practice.
On this view, while biological features exist, what they socially mean — what counts as a man or a woman, what roles attach, how the categories are policed and revised — is the work of social practice. The categories are real but constructed; revising them …

Should we edit the human germline?
Whether human nature is a given biological kind, a constructed category, a relational achievement, a family-resemblance cluster, or a conventional distinction within deeper unity is the ontological question the policy debate over heritable gene editing is mostly about.
The categories we count as 'human' are emergent from practice; germline editing is a practice-revision like any other.
On this view, biological facts about the genome exist, but what we count as 'human nature' is downstream of practice. The germline is one more thing humans now have technical access to; the question is not whether the practice transgresses an essence but whether the …
Roads not taken Human nature is a real biological kind given by reproductive biology or by creation; editing the germline transgresses what is given.

Is the world created from nothing?
Creatio ex nihilo is one of the most distinctive Western-theological claims. Whether matter was created from nothing, eternally exists, or is sustained moment-by-moment turns on what kind of thing matter is.
Matter is real but emerges from something deeper — neither bedrock nor created-from-nothing.
On this view, matter is genuinely there, but it isn't the floor of reality. It depends on something more fundamental — dependent origination, mind, divine sustaining act, computational substrate, or the structure of conditions — and is conserved only at its own level of description. …
Roads not taken Yes — matter was created and is conserved as a real substance. (55%) · Matter is constituted by relations; the question of 'from what?' presupposes substance. (16%) · Matter arises and dissolves through cosmic rounds; neither created from nothing nor eternal. (4%)

When does a person begin?
The political question of abortion sits atop an older ontological one: at what point does there exist a someone — a being with moral standing — rather than merely the materials from which one will form?
A person comes into being gradually, as the capacities of a mind develop.
On this view, personhood is not a status conferred at a moment but a property of beings with certain capacities — to feel, to suffer, to prefer, eventually to reflect. A zygote has none of these; a late-term fetus has many; a newborn has most. …

What is marriage?
Behind every disagreement about how marriage should be defined is a prior disagreement about what kind of thing it is — a given order to be recognized, a practice to be negotiated, or a web of relations to be woven.
Marriage is a practice we shape — its content is what we make it.
On this view, marriage is a human institution shaped by law, custom, and the agreements of those who enter it. There is no fixed essence to discover, only practices to negotiate. As societies change — granting women legal personhood, recognizing no-fault divorce, extending the institution …

Could causation work backwards? Causation runs one way — the arrow of time is real and structural. 68% Is the asymmetry between memory and anticipation a real feature of time, or just of us? The asymmetry is real because time itself has a real direction. 68% Is the arrow of time a real feature of the cosmos, or only of how we describe it? The arrow is real and structural; the asymmetry isn't an artifact of description. 68% Is environmental damage ever truly permanent? Damage is real and permanent on the relevant timescales. There is no recovery; there is only limitation. 66% Can a civilization recover from collapse? Civilizational complexity is hard to build and easy to lose; recovery is at best partial. 66% Does the second law of thermodynamics mean something morally? Entropy is what time is. The moral weight, if any, is the weight of working against the current. 66% What is our place in nature? Active in a real nature — we cultivate, steward, transform. 48% Should we colonize space? Cultivating worlds beyond Earth is the next form of stewardship. 48% Is genetic engineering of food stewardship or domination? Genetic modification is cultivation by other means. 48% Is reality fundamentally digital? No — continuous divine sustaining act, the Tao that knows no joints, the One's self-disclosure. 44% Are there indivisible units of experience? No — continuous divine presence; consciousness is the unbroken witness. 44% Is memory stored or reconstructed? Held in continuous divine or ancestral remembering — neither stored discretely nor purely reconstructed. 44% Can prayer for someone far away affect them? Prayer reaches because God or a cosmic ordering acts on the prayed-for. 37% Are coincidences ever more than coincidence? What looks like coincidence is providence — there is no such thing as a real coincidence. 37% Are the dead morally present to the living? The dead are present through divine memory, communion of saints, or ancestor presence. 35% Is divine omniscience compatible with human freedom? The human observer is in time, but God's vantage is not — and foreknowledge is not foreordering. 33% Does meditation reveal something genuinely timeless? Meditation participates in a real eternity — divine or cosmic — that the bounded human observer ordinarily cannot reach. 33% Does prayer change God's mind? God sees from outside time; prayer doesn't change God's mind, but it is part of how providence is enacted. 33% Do animals have moral standing comparable to humans? Animal minds are real because biology is the substrate of mind. 32% Could a fetal brain organoid in a petri dish be conscious? Brain tissue can in principle do what brains do; the question is integration. 32% Should we trust expert testimony when we can't verify it? Trust expertise whose conclusions a competent mind can in principle reproduce. 32% Is religious revelation a real source of knowledge? Revelation is evaluable by reason — and not above it. 32% Does an LLM 'know' the things it correctly produces? An LLM can produce correct outputs but not reason to them; useful, not knowing. 32% Could an AI have a mind that matters? No — mind is what a biological brain does, and an LLM has no brain. 30% What makes someone the same person over time? You are a soul — what persists through change is the non-bodily aspect. 29% Is the late-stage dementia patient still the person their spouse married? The soul persists; the cognitive change is the body's, not the person's. 29% If a teleporter copied and destroyed you, would you have survived?
