The Intertwining of Philosophy and Religion in the Western Tradition
Chapter 1. The Intertwining of Philosophy and Religion in the Western Tradition
🧭 Overview
🧠 One-sentence thesis
Throughout most of Western history, philosophy and religion have been deeply interconnected rather than separate domains, with the majority of philosophers holding religious beliefs that often shaped their philosophical work.
📌 Key points (3–5)
- Historical intertwining: From ancient Greece through the 1800s, philosophy and religion were not distinct categories but overlapping pursuits addressing life's "Big Questions."
- Shared vocabulary and concepts: Greek philosophical terms (especially Logos from Stoicism and Platonism) directly influenced Jewish and Christian theological writings, including the New Testament.
- Modern shift: Only in the 1800s–1900s did atheistic philosophy gain a foothold, partly due to Logical Positivism's theory of meaning (not simple closed-mindedness).
- Common confusion: The reputation of philosophers as dogmatically atheist stems from misunderstanding one 20th-century school (Logical Positivism) and ignoring 2,000+ years of history.
- Contemporary resurgence: Since mid-20th century, philosophy of religion has experienced renewed growth, with ~15% of philosophers and over 70% of philosophy-of-religion specialists affirming belief in God.
🏛️ Ancient foundations: Philosophy as spiritual practice
🏛️ Pre-Socratic and classical Greek thought
- Early Greek philosophers regularly discussed divine matters:
- Thales: "all things are full of gods"
- Pythagoras: taught reincarnation and mystical practices
- Parmenides: presented philosophy as a spiritual vision revealed by divine beings
- Aristotle called his Metaphysics "theology," not a separate secular discipline.
🧘 Plato's spiritual philosophy
Ancient Platonists summarized Plato's philosophy as homoiosis theou—"becoming like God."
- Plato described philosophy as "practicing for death"—separating the soul from the body to gain pure knowledge.
- His descriptions sound like out-of-body mystical experiences, not merely "thinking deeply."
- The Republic frames philosophy as answering "how we are to live our lives"—the same goal many religious believers pursue.
- Don't confuse: Modern "philosophy" (critical thinking about questions) with ancient "philosophy" (a spiritual path with theoretical underpinning).
🌉 The Logos as bridge concept
- Stoics: believed the universe was guided by divine Logos ("Word" or "Reason").
- Philo of Alexandria (Jewish philosopher, c. 20 BCE–50 CE): described the Logos as "second god," "first-born Son of God," drawing on both Stoicism and Platonism.
- New Testament: The Gospel of John opens with "In the beginning was the Logos," using Philo's term.
- This term functioned as a conceptual bridge between Jewish and Hellenistic (Greek) thinking.
Example: When the author of Hebrews contrasts the earthly temple with a heavenly "copy and shadow," this echoes Plato's Analogy of the Cave (prisoners seeing only shadows of copies). The vocabulary is philosophical, the context is religious—showing no sharp boundary.
📜 Medieval synthesis: Theology and philosophy unified
📜 Neo-Platonism as spiritual science
- Plotinus (c. 203–270 CE): described mystical experiences of union with "The One" (Plato's highest principle), calling it "Father" and "God."
- He saw Platonism not as mere theory but as a spiritual path leading to direct experience.
- Numenius of Apamea: explicitly tried to show overlap between Platonism and Judaism, coining the phrase "What else is Plato than a Moses who speaks Greek?"
⚔️ Competing spiritual schools
- Early Christians criticized "philosophy" (meaning Platonism) not because they opposed critical thinking, but because Christianity and Platonism were rival schools of spirituality with overlapping yet conflicting teachings.
- Porphyry (Plotinus' student): wrote a 15-volume work Against the Christians because he saw Christianity as a major threat to Platonism.
- Later Platonists incorporated theurgy (ritualistic practices) to compete with Christian liturgy.
🕌 Medieval thinkers across traditions
After 529 CE (when public funding for pagan schools ended), philosophical work continued within religious contexts:
| Tradition | Representative thinkers |
|---|---|
| Greek-speaking Christians | Basil the Great, Gregory of Nyssa, John of Damascus, Gregory Palamas |
| Latin-speaking Christians | Augustine, Anselm, Aquinas, Ockham |
| Muslims | Al-Kindi, Al-Farabi, Ibn Sina, Al-Ghazali, Ibn Rushd |
| Jews | Saadia Ben Gaon, Maimonides, Gersonides |
- All gave "intense scrutiny to many philosophical questions" but "always did so with one eye towards the religious or theological implications."
🔬 Modern period: Questioning yet still engaged
🔬 Early Modern Rationalists and Empiricists
Despite revolutionary changes (Renaissance, Scientific Revolution, Reformation), Early Modern philosophers remained deeply concerned with religious questions:
Rationalists:
- Descartes: Meditations largely concerned with proving God's existence and the soul's distinction from body.
- Spinoza: argued for pantheism in his Ethics.
- Leibniz: wrote versions of Cosmological and Ontological arguments, plus Theodicy (response to Problem of Evil).
British Empiricists:
- Locke: deeply religious; his political philosophy begins from the premise that we are God's property.
- Berkeley: a bishop; his idealism required God as the mind that perceives and sustains all things.
- Hume: the first who could reasonably be called atheist, though more accurately held "attenuated deism"—belief in some Creator, but unknowable and uninvolved.
🌍 German Idealism
- Kant: described his Critique of Pure Reason as denying knowledge "in order to make room for faith."
- Hegel: conceptualized his philosophy around the Christian doctrine of the Trinity, which he was trying to revive.
⚡ The 1800s turning point
- Only with Marx and Nietzsche do atheistic philosophies gain a lasting foothold.
- Yet both were deeply concerned with religious questions—they simply came down on the negative side.
- Nietzsche even called Christianity "Platonism for the masses," acknowledging the connection.
🔄 20th century to present: Reputation vs reality
🔄 The Logical Positivist episode
- Logical Positivists (Vienna Circle, 1924–1936) held that religious talk was meaningless (not just false).
- This sounds insulting, but it followed logically from their theory: the meaning of a sentence is just the conditions under which it could be verified to be true.
- From this premise, talk about God, morality, aesthetics, and cause-and-effect all became meaningless—religion wasn't singled out.
- Don't confuse: Logical Positivism's dismissal of religious language with general philosophical closed-mindedness. It was a consequence of a specific (now-defunct) theory of meaning, not mere prejudice.
🌱 Continued engagement even among non-believers
Even during 20th-century atheism's peak, many philosophers remained engaged with religion:
- Wittgenstein: said "I cannot help seeing every problem from a religious point of view"; expressed regret when his influence made a friend less religious.
- Anscombe and Geach: Wittgenstein's students, both devout Roman Catholics and major philosophers.
- Continental philosophers: Husserl converted to Christianity in his twenties; Heidegger began as a Catholic seminarian; Sartre described existentialism as "an attempt to draw the full conclusions from a consistently atheistic position" (showing the question's importance); Foucault and Derrida remained deeply engaged with religious themes.
📈 Contemporary resurgence
Since mid-20th century, especially in Analytic Philosophy:
- Alvin Plantinga and colleagues (William Alston, Nicholas Wolterstorff, Peter van Inwagen, Richard Swinburne, William Lane Craig) mounted sustained defenses of theistic belief's rationality.
- Philosophy of religion has seen an "explosion" of interest.
- Current data: ~15% of professional philosophers believe in or lean toward God; ~30% among medievalists; over 70% among philosophy-of-religion specialists.
Two interpretations of the last statistic:
- Arguments for religious belief are stronger, and specialists (best positioned to judge) find them convincing.
- Self-selection: atheists are less likely to specialize in philosophy of religion.
❓ Open questions for the future
❓ Historical accident or natural affinity?
The excerpt leaves unresolved whether:
- The 2,000+ year connection between philosophy and religion reflects a "deep, natural affinity between the two," OR
- The decline in the 1800s–1900s means "philosophy finally managed to rid itself of an irrational relic," OR
- The recent resurgence will prove lasting, making the atheistic century "the blip on the radar."
❓ Definitions matter
Throughout the excerpt, the difficulty of sharply distinguishing "philosophy" from "religion" recurs:
- Scholars debate whether Confucianism and Buddhism are "really" religion or "only" philosophy—or both, or neither.
- In the West, a sharp division developed only after the Enlightenment.
- Before then, thinkers "did not see two categories here, but one."
Key insight: How we define these terms shapes whether historical facts (like Aristotle calling his work "theology" or the New Testament using Stoic/Platonic terms) seem natural or puzzling.
