Dynamis
The Greek concept of potentiality and inherent power, central to Aristotle's metaphysics.
The Meaning of Dynamis
Dynamis meant power, capacity, and potentiality — three ideas the Greeks saw as one. A seed has the dynamis to become a tree. A wrestler has the dynamis to throw his opponent. A city has the dynamis to wage war. Aristotle made dynamis the cornerstone of his metaphysics, pairing it with energeia (actuality) to explain how change is possible. The acorn is potentially an oak; when it grows, potentiality becomes actuality. This framework resolved the puzzle Parmenides had posed: how can something come from nothing? It cannot, Aristotle answered — it comes from dynamis, which is not nothing but not yet something. Thucydides used dynamis politically — Athenian power was dynamis, and the growth of Athenian dynamis was what made the Peloponnesian War inevitable. The Hippocratic writers used it medically — each drug had a dynamis, a specific power to heat, cool, dry, or moisten the body. Plato explored dynamis in the Sophist, defining being itself as the capacity to act or be acted upon. The word generated an extraordinary family of English descendants.
