Episode 45: Stoic Physics and Esoteric Metaphysics

Stoic physical theory is a fascinating subject in its own right, but in this episode we try to do the right thing and concentrate on the key concepts of the Stoa’s thoughts about how the world works which have strong resonances in western esotericism. We break down the basics of three key points of reference – pneuma, sympatheia, and logos – giving a simplified explanation of how they work in Stoic theory and then adumbrating how they developed and mutated in various esoteric traditions of antiquity and down the centuries thereafter.

Special thanks to Dr Paul Scade for his insights into Stoic Physics and related subjects (because, for the Stoics, it’s all related!), and for the cracking bibliography.

Works Discussed in this Episode:

Primary:

  • Anaximines DK B2.
  • Brown, James (1970). Super Bad (King Records 6329).
  • John: the famous opening lines of the Gospel of John: Ἐν ἀρχῇ ἦν ὁ λόγος, καὶ ὁ λόγος ἦν πρὸς τὸν θεόν, καὶ θεὸς ἦν ὁ λόγος.
  • Praxagoras of Cos: his work survives only in Galen and other ancient medical writers. I haven’t bothered to dig up the original references, but the wikipedia article pretty much tells you what you need to know.
  • Sinistrari, Ludovico Maria, Demoniality (De daemonialitate et incubis et succubis, MS 1680, printed 1875. The original Latin with English translation (1875) can be found online.

Secondary:

  • Kirk, G., 1954. Heraclitus: The Cosmic Fragments. Cambridge University Press, Cambridge.
  • Mortley, R., 1986. From Word to Silence. Hanstein, Bonn. Two vols. We quote Volume I, p. 16.
  • Sambursky, S., 1959. Physics of the Stoics. Princeton University Press, Princeton, NJ. Suggests that the Stoic theory of pneumatic tonos might be considered the first ‘field theory’ in western physics.

Recommended Reading:

Our surviving evidence for Stoic physics and metaphysics is limited and often extremely difficult to access. No complete Stoic text survives from the hand of the first three heads of the Stoa. Unfortunately, while the major Roman Stoics were very interested in ethics, they wrote very little on the physical side of the philosophy. As a consequence, the technical details often have to be reconstructed from highly fragmentary evidence transmitted by later writers who often had agendas of their own.

The community of scholars working on Stoic physics and metaphysics is relatively small, in part due to the difficulty of the source material and of the theories themselves, and in part due to a much greater modern interest in the ethics of the school. As such, scholarly developments move relatively slowly and the range of literature available is narrower than that for many other major philosophical schools.

Starting Points

The most valuable starting points for reading about the Stoics, and about their physics in particular, are two works published in the 80s and 90s that were important milestones in the study of Hellenistic philosophy more broadly.

  • Long, A.A., & Sedley, D.N., 1986, The Hellenistic Philosophers, 2 vol., Cambridge.

Long and Sedley, as it is known, marked a seminal jumping off point for the modern study of the Stoics. Volume I, p. 266-343 devotes a chapter to each major topic related to Stoic physics. Each chapter collects together the most important primary sources and then discusses them in a short interpretative essay (normally 2-3 pages). These essays have provided the foundations for most subsequent scholarly discussions.

  • Algra, K.A., Barnes, J., Mansfeld, J. and Schofield, M. (eds.), 1999, The Cambridge History of Hellenistic Philosophy, Cambridge.

The Cambridge History of Hellenistic Philosophy brings together important discussions from the major figures working on the subject, summarising the state of scholarly play at the end of the ’90s and is the most recent comprehensive treatment of the topic. David Sedley provides a wide-ranging analysis of Stoic physics at p. 382-411, while David Furley discusses Stoic cosmology at p. 432-451. Jaap Mansfeld’s chapter on theology (p. 452-478) does not divide itself by schools, rather treating the various Hellenistic theories alongside each other, but the reflections on Stoicism here are no less valuable for that.
