What is Platonism?

The Philosophy of Plato

Platonism refers to the philosophical system developed by Plato and subsequent schools of thought that are closely derived from his core doctrines. While modern Platonists may not adhere to every single tenet of Plato's original philosophy, the fundamental assertion remains: the existence of abstract objects. This concept posits a "third realm" of existence, distinct from both the tangible, sensible world we perceive and the subjective internal world of consciousness. This stands in direct opposition to nominalism, which denies the existence of such abstract entities.

Abstract Objects and Reality

The abstract objects central to Platonism encompass a wide array of concepts, including properties, types, propositions, meanings, numbers, sets, and truth values. Philosophers who affirm the existence of these non-spatial, non-temporal, non-physical, and non-mental objects are often termed Platonists. Conversely, those who reject their existence are referred to as nominalists. It is important to note that these modern definitions of "Platonism" and "nominalism" have evolved and may differ from their historical applications.

Two Realities: Sensible vs. Intelligible

At its core, Platonism, particularly through its Theory of Forms, establishes a crucial distinction between two types of reality. One reality is perceptible through our senses but is ultimately unintelligible and constantly in flux, akin to the philosophy of Heraclitus. This is the realm studied by physical sciences. The other reality is imperceptible to the senses but is purely intelligible and unchanging, aligning with the philosophy of Parmenides. This higher reality is the domain of mathematics and pure reason. Plato's deep interest in geometry, influenced by Pythagoras, underscored this distinction.

The Theory of Forms

Perfect Archetypes

The Theory of Forms is the cornerstone of Plato's metaphysics. It posits that true being is founded upon these Forms, which are eternal, unchangeable, and perfect archetypes. The particular objects we encounter in the everyday sensible world are merely imperfect copies or reflections of these perfect Forms. Because the objects of sense are perpetually changing, they are considered to lack genuine, stable existence. The number of Forms corresponds to the universal concepts that can be derived from these particular sensible objects.

The Form of the Good

In Plato's seminal work, the Republic, the highest of all Forms is identified as the Form of the Good (Greek: แผก ฯ„ฮฟแฟฆ แผ€ฮณฮฑฮธฮฟแฟฆ แผฐฮดฮญฮฑ, 'idea of the good'). This supreme Form is considered the ultimate source of all other Forms, and the very being and knowability of all other Forms are contingent upon it. Knowledge of the Forms, particularly the Form of the Good, cannot be attained through sensory impressions. Instead, it is achieved through the soul's internal activity, detached from sensory distractions, primarily through the rigorous exercise of reason.

This excerpt from Plato's Republic (Book V, 475e-476d, translation G. M. A. Grube) illustrates the distinction between lovers of sights and sounds and true philosophers:


[Socrates:] "Since the beautiful is opposite of the ugly, they are two."
[Glaucon:] "Of course."
"And since they are two, each is one?"
"I grant that also."
"And the same account is true of the just and unjust, the good and the bad, and all the forms. Each of them is itself one, but because they manifest themselves everywhere in association with actions, bodies, and one another, each of them appears to be many."
"That's right."
"So, I draw this distinction: On one side are those you just now called lovers of sights, lovers of crafts, and practical people; on the other side are those we are now arguing about and whom one would alone call philosophers."
"How do you mean?"
"The lovers of sights and sounds like beautiful sounds, colors, shapes, and everything fashioned out of them, but their thought is unable to see and embrace the nature of the beautiful itself."
"That's for sure."
"In fact, there are very few people who would be able to reach the beautiful itself and see it by itself. Isn't that so?"
"Certainly."
"What about someone who believes in beautiful things, but doesn't believe in the beautiful itself and isn't able to follow anyone who could lead him to the knowledge of it? Don't you think he is living in a dream rather than a wakened state? Isn't this dreaming: whether asleep or awake, to think that a likeness is not a likeness but rather the thing itself that it is like?"
"I certainly think that someone who does that is dreaming."
"But someone who, to take the opposite case, believes in the beautiful itself, can see both it and the things that participate in it and doesn't believe that the participants are it or that it itself is the participantsโ€”is he living in a dream or is he awake?
"He's very much awake."

Dialectic and Primordial Kinds

Dialectic, for Plato, is the supreme science and the essential instrument for this intellectual ascent. It is the method that guides us towards the knowledge of the Forms and ultimately to the highest Form of the Good. In a later work, the Sophist, Plato also enumerates certain primordial "Great Kinds" among the Forms, specifically listing being, sameness, and difference, indicating a continued refinement of his metaphysical framework.

Platonist Ethics

Virtue as Knowledge

Platonist ethics is intrinsically linked to the Form of the Good. For Plato, virtue is fundamentally knowledgeโ€”specifically, the recognition and understanding of this supreme Form of the Good. This intellectual understanding guides moral action, suggesting that to know the good is to do the good. This intellectualist approach to ethics emphasizes the rational pursuit of moral excellence.

The Tripartite Soul and Virtues

Plato's theory of the soul is central to his ethics. He posited that the soul comprises three distinct parts: reason, spirit (or thumos), and appetite. Each part, when functioning optimally, contributes to specific virtues:

  • Reason: Cultivates Wisdom.
  • Spirit: Fosters Courage.
  • Appetite: Leads to Moderation (or temperance).

The overarching virtue of Justice serves as the unifying bond, ensuring that each part of the soul performs its proper function harmoniously, leading to a well-ordered individual and, by extension, a just society.

Immortality of the Soul

Francis Cornford, a prominent scholar, identified the twin pillars of Platonism as the Theory of Forms and the doctrine of the immortality of the soul. This belief in an eternal soul that can ascend to grasp the Forms provides a profound metaphysical basis for Plato's ethical framework. The soul's journey towards knowledge and virtue is not confined to a single lifetime but is part of a larger, enduring existence.

The Platonic Academy

Founding and Early Years

Plato established his renowned Academy in Athens, a sacred grove where he delivered his lectures. This institution became the intellectual heart of Platonism and continued to thrive long after his death. The Academy's early period, known as the Old Academy, was led by Plato's immediate successors, who further developed and interpreted his philosophy. These early figures included Speusippus, Plato's nephew, who headed the school until 339 BC, and Xenocrates, who led until 313 BC.

Pythagorean Synthesis

Both Speusippus and Xenocrates were instrumental in the Old Academy's intellectual trajectory. They sought to integrate Pythagorean speculations concerning number theory with Plato's Theory of Forms. This synthesis aimed to find a deeper mathematical structure underlying the Forms, reflecting Plato's own admiration for geometry and the abstract precision of mathematics as a path to understanding ultimate reality.

Socrates' Enduring Voice

Platonism's initial expression is found primarily in Plato's dialogues, where the character of Socrates often serves as the primary expositor of philosophical doctrines. While it is debated how closely these doctrines align with the historical Socrates' own thoughts, Plato masterfully used his teacher's voice to articulate and explore complex philosophical ideas, laying the groundwork for centuries of Western thought.

Evolution of Platonism

The Skeptical Academy

The Platonic Academy underwent a significant transformation around 266 BC when Arcesilaus became its head, ushering in the period known as the Middle Academy. This phase was characterized by a strong emphasis on philosophical skepticism, particularly through its critiques of the Stoics' claims of certain truth and knowledge. The New Academy, beginning with Carneades in 155 BC, continued this skeptical tradition, denying the possibility of absolute truth. Both Arcesilaus and Carneades contended that their skeptical stance was a genuine interpretation of Plato's own teachings.

Middle Platonism

A shift occurred around 90 BC when Antiochus of Ascalon rejected skepticism, initiating the era of Middle Platonism. This period saw a fusion of Platonism with elements from Peripatetic and Stoic philosophies. A key development was the reinterpretation of Platonic Forms: they were no longer seen as entirely transcendent but rather as immanent within rational minds. Furthermore, the physical world was conceived as a living, ensouled entity, embodying the "World-Soul." Prominent figures like Plutarch exemplify this eclectic approach, which also saw Platonism integrated into Pythagoreanism (e.g., Numenius of Apamea) and Jewish philosophy (e.g., Philo of Alexandria).

Neoplatonism

The 3rd century AD marked another profound evolution with Plotinus, who established Neoplatonism by integrating Middle Platonism with mystical elements. In this system, the ultimate reality is "the One" or "the Good," the transcendent source from which all existence emanates. From the One, reason (the nous), containing an infinite store of ideas, is generated. The World-Soul, a copy of the nous, is then generated and, by informing non-existent matter, constitutes the physical world. Neoplatonism emphasizes the soul's yearning to escape its material bondage and ascend through virtue and philosophical contemplation to achieve ecstatic union with the One. Plotinus's disciples, such as Porphyry and Iamblichus, further developed this system, often in conscious opposition to nascent Christianity. The Platonic Academy was re-established during this period, with Proclus being a celebrated commentator, until its closure by Emperor Justinian in 529 AD.

Enduring Influence

Christianity and Platonism

Platonism exerted a profound influence on Western thought, particularly on Christianity. Many Platonic concepts found a permanent place within Christian theology. Early Christian thinkers like Clement of Alexandria and Origen, along with the Cappadocian Fathers, were influenced by Platonism. Saint Augustine, a Doctor of the Catholic Church, was heavily shaped by Neoplatonism, particularly Plotinus's Enneads, which laid foundations for much of Western Christian thought. The Christian church often interpreted Plato's Forms as God's thoughts, a position known as divine conceptualism. Platonism was considered authoritative throughout the Middle Ages and influenced both Eastern and Western Christian mysticism.

Islamic and Esoteric Traditions

Beyond orthodox Christian teachings, Platonism also influenced various gnostic and esoteric traditions that circulated in the ancient world. This includes major historical religions like Manichaeism, as well as Mandaeism and Hermeticism. During the European Renaissance, a renewed interest in Hermeticism and direct Platonic philosophy, alongside Jewish mysticism and Islamic alchemy, led to a culmination of various permutations of Platonic thought in the magic and alchemy of the period. Furthermore, figures like Julius Evola and Arturo Reghini incorporated Platonic metaphysics into their visions for Roman pagan revival, aligning with their critiques of modernity.

Christoplatonism

A specific term, "Christoplatonism," describes a dualistic perspective, often attributed to Plato, which posits that spirit is inherently good while matter is inherently evil. This dualism influenced certain Christian churches, despite directly contradicting the biblical narrative where God declares all creation as "good." Consequently, Christoplatonism receives ongoing criticism from many contemporary Christian teachers, including the Methodist Church, for its divergence from core biblical tenets.

Platonism in Modern Thought

Renaissance and Beyond

The Renaissance witnessed a significant resurgence of interest in Platonic thought, with scholars engaging directly with Plato's original works. In 16th, 17th, and 19th-century England, Plato's ideas profoundly influenced numerous religious thinkers, most notably the Cambridge Platonists. However, orthodox Protestantism in continental Europe often viewed natural reason with distrust and was frequently critical of Platonism. This period also saw discussions on how to interpret the same-sex elements within Plato's corpus.

Modern Abstract Objects

Beyond its historical forms, Platonism in contemporary philosophy often refers to the theory of abstract objects in a modern sense. This view asserts the existence of abstract objects that do not exist in space or time and are entirely non-physical and non-mental. This modern interpretation of Platonism has been embraced by numerous philosophers, including Bernard Bolzano, who argued against psychologism. Plato's works also significantly influenced 20th-century philosophers such as Alfred North Whitehead with his Process Philosophy, and Nicolai Hartmann's critical realism and metaphysics.

Analytic and Continental Perspectives

In contemporary analytic philosophy, many Platonists trace their intellectual lineage to Gottlob Frege's influential paper "Thought," which advocated for Platonism regarding propositions, and his book The Foundations of Arithmetic, which argued for Platonism concerning numbers and became a foundational text for the logicist project. Prominent analytic philosophers who espoused metaphysical Platonism include Bertrand Russell, Alonzo Church, Kurt Gรถdel, W. V. O. Quine, David Kaplan, Saul Kripke, Edward Zalta, and Peter van Inwagen. Iris Murdoch also championed Platonism in moral philosophy in her 1970 work, The Sovereignty of Good. However, Paul Benacerraf's epistemological challenge remains a significant criticism. In continental philosophy, Edmund Husserl's arguments against psychologism are seen as deriving from a Platonist conception of logic, influenced by Frege, Bolzano, G. W. Leibniz, and Hermann Lotze. Other notable continental philosophers with an interest in Platonism include Leo Strauss, Simone Weil, and Alain Badiou.
