Tradition: Byzantine Platonism / Renaissance Plato-Aristotle controversy
Plato is superior to Aristotle in theology, ethics, and metaphysics — and the Latin West has been led astray by preferring the student to the master
De Differentiis is the work that launched the fifteenth-century controversy over the relative merits of Plato and Aristotle — the most consequential philosophical debate of the Renaissance. Composed around the time of Pletho's attendance at the Council of Florence (1438–39), it argues systematically that Plato is superior to Aristotle on every major philosophical question: the nature of God (Plato's One is a better theology than Aristotle's unmoved mover), the Forms (Aristotle's rejection of separately existing Forms is a philosophical regression), the soul (Plato's doctrine of immortality and pre-existence is correct; Aristotle's is ambiguous at best), and ethics (Plato's vision of the Good is higher than Aristotle's prudential ethics). The treatise provoked responses from George of Trebizond (a furious Aristotelian rebuttal), Cardinal Bessarion (a moderate defense of Plato in "In Calumniatorem Platonis"), and many others. The debate stimulated the demand for Latin translations of Plato that Ficino would supply, and thus directly catalysed the Renaissance Platonist revival.

School Embodiments
De Differentiis is the most forceful 15th-century argument for Plato's superiority over Aristotle — on God, the Forms, the soul, and ethics. It launched the controversy that produced the Renaissance Platonist revival.
"Plato's doctrine of the One beyond being is a better theology than Aristotle's unmoved mover, which is merely the highest in a series of natural causes." (De Differentiis)
Neo-Platonism
25%
Pletho's Plato is read through the Neoplatonic tradition — Plotinus, Proclus, the Chaldean Oracles — and the hierarchy of the One, Intellect, and Soul structures the argument throughout.
"The Forms are not in the mind of God as Aristotle's categories are in the mind of a logician — they are the eternal self-thinking thoughts of the One." (De Differentiis)
Aristotelianism
15%
A negative influence: De Differentiis is written against Aristotle. But Pletho takes Aristotle seriously enough to argue against him point by point, and the work presupposes deep knowledge of the Aristotelian corpus.
"Aristotle, having learned from Plato, rejected his master's best doctrines — the separately existing Forms, the immortality of the individual soul, the transcendence of the Good." (De Differentiis)
Pletho situates Plato within a prisca theologia: Zoroaster, the Chaldean Oracles, and Pythagoras anticipate Plato, and together they represent the true ancient wisdom.
"Plato recovered the ancient theology of Zoroaster and the Chaldeans, which Aristotle abandoned in favour of his own innovations." (De Differentiis)
Written by a Byzantine scholar at a church council, De Differentiis operates within the Greek intellectual tradition, though Pletho's private sympathies were more pagan-Platonist than Orthodox.
"The Greek Fathers — especially the Cappadocians and Pseudo-Dionysius — were Platonists, not Aristotelians; the Latin West's preference for Aristotle is a departure from the patristic tradition." (De Differentiis)
Internal Tensions
De Differentiis sparked a controversy that consumed a generation of scholars: George of Trebizond's response was so vituperative that Cardinal Bessarion had to write In Calumniatorem Platonis (Against the Calumniator of Plato) to moderate the debate. The deeper tension is that Pletho's private Platonism was pagan — his Laws proposed to replace Christianity with a Hellenic theology — while De Differentiis presents Plato as merely a better philosopher than Aristotle, not as an alternative to Christ. The work's lasting significance is that it initiated the demand for Latin Plato that Ficino would satisfy, thereby catalysing the Renaissance Platonist movement.

How much weight do future people deserve?
If a billion people will exist in the 25th century, do their interests count for as much as the interests of a billion people alive now? The answer turns on what kind of reality the future has.
From the One's vantage, generations are themselves conventional.
On non-dual views, the distinction between present and future people is itself perspectival within a single underlying reality. Obligation across generations remains real at the conventional level where moral life happens; the metaphysical claim that future people 'exist' or 'don't yet exist' as a final …

Is regret rational?
If the past is fixed and unchangeable, what kind of mental act is regret? An error, a duty, a lesson, a perspective on a moment that is still in some sense present?
From the One's vantage, regret is itself a conventional category.

Do we owe extinct species something we cannot give them?
A species that no longer exists cannot be helped, cannot be consulted, cannot benefit. Whether anything is owed to it anyway turns on what kind of reality past beings have.
From the One's vantage, species and extinction are themselves conventional.
On non-dual views, the species we mourn — and the act of mourning — operate at the conventional level. Compassion for the extinct, like compassion for the living, remains; the metaphysical question of what we 'owe' the extinct presupposes a framework of distinct beings and …

Do you really choose?
If the brain is a physical system and physical systems are governed by laws, then every choice is also a chain of causes — which raises the question of what was really left to choose.
Choice is real within a determined order — agency and determinism aren’t opposites.
On this view, the future is determined and you are genuinely choosing. Those aren't contradictory because the determination runs through you rather than around you: your reasoning, deliberation, and assent are the way the determined outcome gets settled. Choice is what it feels like from …

Are addicts responsible for their addiction?
Addiction looks from one angle like the textbook case of agency failing — a person doing what they don't, in any meaningful sense, want to do. From another angle it looks like agency at work in hard conditions. Which it is depends on what agency is.
The addict is genuinely responsible within a determined order.
On this view, the addict is acting within a determined order but is genuinely acting — making decisions, endorsing or resisting urges, seeking or refusing help. Responsibility attaches not because some uncaused choice happened, but because the addict is the kind of agent through which …

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's apparent diversity is convention over a single underlying value.
On non-dual views, the diverse forms money takes are perspectival distinctions within a single underlying value — labor, energy, attention, or simply the One from which all value derives. The metaphysical question is mostly malformed at the conventional level where monetary policy lives, but the …

Nations are conventional partitions of a single humanity.
On non-dual views, the distinctness of nations is a perspectival distinction within a deeper unity — one humanity, one consciousness, one underlying reality. Nations matter at the conventional level where ordinary politics lives, but the metaphysical weight they sometimes claim is unsupported.

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 distinction between edited and unedited is conventional within a deeper non-dual reality.

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. …

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?
From the standpoint of the One, the question doesn’t apply in the form it is asked.
On non-dual views, the apparent plurality of selves is itself a perspectival distinction within a deeper unity. The question of when one self begins within that One is conventional, not ultimate. What follows ethically is then a question for the conventional level — which is …

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.
All union is participation in the One — particular forms are conventional.

Should we colonize space?
The drive to extend human presence beyond Earth is sometimes framed as the next chapter of stewardship, sometimes as hubris, sometimes as escape from problems we ought to solve here. Which it is depends on what we take our relationship to nature to be.
From the standpoint of the One, expansion across substrate is just movement within the same.
On non-dual views, the difference between Earth and elsewhere is conventional — particular locations within a single underlying reality. Space colonisation as escape is therefore incoherent; nothing is escaped because nothing was elsewhere to escape from.
