Pierre Hadot

Pierre Hadot was born in 1922 in Paris and educated at the seminary of Reims, where he initially trained for Catholic priesthood. He left the priesthood in 1952; he later wrote that his theological training had given him a particular feel for the ancient philosophical texts as living spiritual documents — a feel that academic philosophy training would not have given him. He spent his career at the Centre national de la recherche scientifique, the École pratique des hautes études, and (from 1982 to 1991) the Collège de France, where he held the chair in Histoire de la pensée hellénistique et romaine.

The principal thesis

Hadot’s foundational claim — articulated across several decades of work — is that ancient Greek and Roman philosophy (the schools of Plato, Aristotle, the Stoics, the Epicureans, the Cynics, the Skeptics, the Neoplatonists) was understood by its actual practitioners as a way of life — a sustained spiritual practice (exercice spirituel) — rather than as a system of theoretical doctrines. The student who entered a philosophical school did not primarily learn a body of propositions; the student took up a discipline that was meant to transform how the student perceived, judged, lived, related to others, and met death.

The argument is supported by careful philological work across the ancient corpus. Hadot showed that the literary forms of ancient philosophy (the dialogue, the maxim, the personal letter, the daily notebook, the philosophical exhortation) were structured for the practical purpose of effecting transformation rather than for the theoretical purpose of articulating a system. The philosophical schools ([[the-garden|the Garden]] of Epicurus, [[stoicism|the Stoa]], the Academy, the Lyceum) were communities of practice — schools in the literal sense of training-grounds — not classrooms in the modern academic sense.

The implications are substantial:

• Ancient philosophy is not best read as a set of theoretical doctrines to be evaluated for truth. It is best read as a set of practical disciplines, each of which produces a particular kind of life.
• The practice survives the death of the school. Even after the institutional schools faded (which happened gradually over the late ancient and early medieval periods), the practical disciplines continued as continuing practices — sometimes within Christian monastic life, sometimes outside it.
• Modern academic philosophy has substantially lost this dimension. The university discipline of philosophy as it has developed in the modern period has largely treated its history as the history of theoretical positions to be evaluated. Hadot’s thesis recovers the philosophical practice tradition that was always there but that the academic frame had largely obscured.

The principal works

Across a long career:

• Plotinus, or the Simplicity of Vision (1963; English 1993). His major scholarly study of the Neoplatonist Plotinus; remains a definitive reading.
• Exercises spirituels et philosophie antique (1981; English as Philosophy as a Way of Life, 1995). The collection of essays that articulated the central thesis.
• Qu’est-ce que la philosophie antique? (1995; English as What Is Ancient Philosophy?, 2002). His most accessible synthetic statement of the position.
• La citadelle intérieure (1992; English as The Inner Citadel: The [[meditations-marcus-aurelius|Meditations of Marcus Aurelius]], 1998). His major study of [[marcus-aurelius|Marcus Aurelius]]; substantially shaped the contemporary recovery of Stoic practice.
• La philosophie comme manière de vivre (2001; English as The Present Alone Is Our Happiness, 2009). Conversations with Jeannie Carlier and Arnold Davidson; an accessible late summary of his thinking.
• Editions and translations of Marius Victorinus, Porphyry, [[marcus-aurelius|Marcus Aurelius]], and others — substantial scholarly contribution.

Influence

Hadot’s thesis has been substantially consequential:

• Foucault explicitly engaged Hadot’s work in his late writings (especially the History of Sexuality volumes), and acknowledged the debt; Foucault’s lectures at the Collège de France in the 1980s drew on Hadot’s framework.
• The modern Stoic-practice movement of the 21st century takes Hadot as one of its principal intellectual sources.
• Religious-studies scholarship has substantially absorbed Hadot’s framework for thinking about the relationship between philosophical and contemplative practice.
• Contemporary philosophy education in some quarters has been substantially reformed in light of Hadot’s recovery — with increased attention to practice, to the philosophical schools as communities, to the lived dimension of philosophical commitment.

What this gives the platform

Three contributions:

1. Theoretical foundation for [[0mn1one|the platform]]‘s posture. [[0mn1one|The platform]] treats spirituality as practiced orientation, not as theoretical position. Hadot is one of the principal philosophical sources for taking this stance seriously and articulating it carefully.
2. A bridge between ancient and contemporary practice. Hadot makes the ancient texts directly available to contemporary readers as living manuals rather than as historical artifacts.
3. An intellectual culture worth participating in. Hadot’s lifework is itself a model: the careful philological-historical work, the willingness to challenge institutional academic frames, the integration of scholarship with the wider question of how to live. [[0mn1one|The platform]] takes this seriously.
