Eclecticism

← Encyclopedia

Eclecticism is the practice of selecting doctrines from several schools of thought rather than adhering to a single one. The word comes from the Greek eklektikos, “selective,” built on the verb eklegein, to pick out — and the choosing it names was, in its original setting, a deliberate method rather than a failure of nerve. To pick out is to exercise judgment: the eclectic holds that truth lies scattered across the systems, no one school owning all of it, and that the philosopher’s task is to gather the sound from each and leave the rest. That this same word would later become a near-insult — a name for the mind too soft to commit — is one of the longer ironies in the history of philosophy.

The ancient pedigree

The term has a genuinely ancient lineage, though a thinner one than its later prominence might suggest. Diogenes Laertius, cataloguing the philosophers in his third-century Lives of Eminent Philosophers, closes his prologue by reporting that a certain Potamo of Alexandria had founded what he called an eklektikē hairesis — an eclectic school or sect — gathering into it what pleased him from each of the existing traditions. The notice is brief, almost an afterthought, and it carries a textual problem of its own: some manuscripts place the remark, with its hedging “not long ago,” as a later interpolation rather than part of the original work. Potamo himself is otherwise nearly a cipher. Whether his “school” was a teaching institution, a loose program, or merely a label a doxographer reached for is impossible to recover; the Souda, the tenth-century Byzantine lexicon, repeats the report without adding substance. What the notice does establish is that by late antiquity the impulse had a name and that the name was understood, then, to describe a positive choice — a hairesis like any other, with criteria of its own.

The impulse it points to was, in any case, far older and far wider than the single school it named. By the first century BCE the rigid boundaries between the Stoa, the Academy of Plato, and the Lyceum of Aristotle had grown porous, worn down by three centuries of mutual argument. The schools no longer faced one another as sealed systems but as a shared vocabulary of problems — the criterion of truth, the end of life, the nature of the good — over which their answers had begun to converge and cross-pollinate. The age did not lack for conviction; it lacked for walls.

Cicero and Antiochus

No figure embodies the porous condition better than Cicero (106–43 BCE). Trained in the skeptical Academy and calling himself an Academic to the end, Cicero drew without embarrassment on Stoic ethics, Academic suspension of judgment, and Peripatetic argument as each suited the matter in hand — voicing Stoic theology through Balbus in De Natura Deorum, Stoic ethics through Cato in De Finibus, and reserving for himself the Academic’s right to weigh all sides and assent to none with finality. His method was not the indifferent magpie’s but the orator-philosopher’s: he held that the probable (probabile, his rendering of Carneades’ pithanon) was as much certainty as the honest mind could claim, and so the gathering of strong arguments from every quarter was not weakness but the only intellectually defensible posture.

His teacher Antiochus of Ascalon (c. 130 – c. 68 BCE) pressed a stronger and more consequential claim. Breaking with the skeptical Academy under which he had been formed, Antiochus argued that the major schools, rightly understood, had been saying much the same thing all along — that the Stoa was in substance a renamed Platonism, the Peripatos a friendly variant, and the apparent quarrels largely verbal. This was not eclecticism in Potamo’s sense of free selection but something more ambitious and more contestable: a thesis of underlying agreement, a claim that the schools could be harmonized because at bottom they already agreed. The distinction matters. To pick the best from rival systems concedes that the systems differ; to argue that they secretly concur is to deny the difference. Both postures would shadow the later history of the word, and the second — harmonization on the premise of hidden unity — would prove the more seductive and the more dangerous.

Middle Platonism and the matrix of Neoplatonism

It is in the centuries that follow Antiochus that eclecticism does its quietest and most lasting work. Middle Platonism — the loose movement of Platonist thinkers from the first century BCE through the second century CE — is often described as eclectic in exactly this sense: Platonic at its core, but absorbing Stoic physics and ethics and Aristotelian logic and metaphysics without apology, reading the absorbed material back into Plato as though it had been there all along. Philo of Alexandria (c. 20 BCE – c. 50 CE) works squarely in this register: a Jewish thinker reading the Torah through a Platonist lens, deploying Stoic moral psychology and the Logos of the philosophical schools to make scripture speak a complete philosophical theology. The same matrix produced the philosophical Hermetica and stands behind the figure of Hermes Trismegistus, whose treatises move freely among Platonic, Stoic, and Egyptian materials.

Out of this Middle-Platonist ferment grew Neoplatonism, and here a careful word is owed. Plotinus and his successors were not eclectics in the loose sense — they were rigorous systematizers who subordinated everything they took to a single Platonic architecture, treating Aristotle’s categories and the Stoic logos as material to be corrected and re-placed rather than simply adopted. The eclecticism lies upstream, in the open boundaries of the schools that made such a synthesis thinkable; the synthesis itself is the opposite of eclectic. The lesson the history teaches is that selection is a stage, not a destination: what begins as gathering-from-many tends, in any mind of real power, to harden into a system of its own, at which point it has ceased to be eclectic and become a school.

The pejorative drift

The word did not stay neutral. To later critics — and the drift is already visible in antiquity, where doxographers used the term to mark a thinker who belonged to no recognized line — eclecticism came to mean borrowing without system, a mind too timid or unoriginal to commit to a position and defend it. That pejorative shadow has clung to the term ever since. It is why historians of philosophy now reach for it warily: the word can describe a genuine and defensible method, or it can merely register the historian’s verdict that a body of thought lacks unity and originality — a charge, not a description. The two uses are easy to confuse, and the confusion has done real damage to the reputations of figures, like the Middle Platonists, whose work was more coherent than the label implies. To call a thinker eclectic is, too often, to have stopped looking for the principle of selection that organized the choosing.

Victor Cousin’s rehabilitation

In the nineteenth century the French philosopher Victor Cousin (1792–1867) mounted the most ambitious attempt to reverse the verdict. Cousin made “eclecticism” the name of his own program — the claim that the history of philosophy reduces to four perennial systems (sensualism, idealism, skepticism, and mysticism), each containing a portion of the truth and a portion of error, and that the true elements scattered across these past systems could be sifted out and gathered into one. For a generation his eclecticism was something close to the official philosophy of the French university, taught in the lycées and defended from the lectern of the Sorbonne. But a method that defines itself as the harvest of all prior systems struggles to say what is distinctively its own, and critics charged that Cousin’s program had no principle of selection beyond his own taste. The attempt did not outlast him by much; within decades “eclecticism” had reverted, in most mouths, to its pejorative sense, and Cousin’s school is now studied chiefly as an episode in the history of French academic philosophy rather than as a living position.

Eclecticism and syncretism

The concept matters most for its bearing on syncretism, with which it is easily confused and from which it must be kept distinct. The two are close but not identical, and the difference is load-bearing. Eclecticism is a stance within philosophy — a conscious way of choosing among doctrines, the act of a deliberating mind that holds truth to be distributed and assembles it on purpose. Syncretism is the broader, often gradual and unplanned, fusion of whole religious and cultural systems, by which gods, rites, and stories merge — frequently without anyone intending or even noticing the merger. One is a method; the other is a process. One has an author; the other, often, has none.

The late-antique world that produced the Hermetic writings, the Gnostic currents, and the pursuit of saving gnosis was saturated with both at once, which is exactly why the two are so hard to disentangle there. The standing temptation — pressed in modern times by the perennialist current and by writers such as René Guénon, and surveyed under the broader heading of perennial philosophy — is to read every resemblance among the traditions as evidence of a single underlying wisdom deliberately compiled and handed down, an eclecticism in Antiochus’ strong sense projected backward onto the whole of human religion. The more careful reading resists that flattening. Some of what the late-antique synthesizers held in common was chosen, the fruit of philosophers picking deliberately across the schools; and some of it simply happened, the slow drift of cults and stories into one another. The line between the two is rarely as clean as either the ancient eclectics or their modern admirers have wished.

Texts and scholarship

The primary witness for the ancient term remains Diogenes Laertius, whose prologue (I.21) carries the Potamo notice; the standard public-domain English is R. D. Hicks’ Loeb (1925), with C. D. Yonge’s Bohn translation (1853) the older alternative. For the porous first-century schools, the indispensable source is Cicero, above all the Academica — preserved in two incomplete recensions and edited with full commentary by J. S. Reid (Macmillan, 1885); the Yonge prose translation (Bohn, 1853) supplies an accessible public-domain English. The skeptical background against which Cicero defined his Academic method is documented in the surviving works of Sextus Empiricus and the relevant books of Diogenes Laertius. Antiochus of Ascalon’s harmonizing thesis is reconstructed chiefly from Cicero (Academica II, the Lucullus) and assessed in the modern literature, including the Stanford Encyclopedia of Philosophy account of his place between the Academy and the Stoa. The eclectic character of Middle Platonism, and the difference between selection and the systematizing synthesis that followed in Neoplatonism, are treated in the standard histories of late-ancient philosophy. The whole question of whether the late-antique resemblances bespeak a compiled perennial wisdom or an unplanned drift sits on the same boundary the ancient term itself was coined to mark: the distinction between an eclecticism that someone performed and a syncretism that merely occurred.
