Greek philosophy distinguishes four types of knowledge. Aristotle described Episteme, Techne, and Phronesis in the Nicomachean Ethics — and contemporary organizational literature adds a fourth, Metis, borrowed from Greek mythology. Together, these four types precisely explain why organizations invest in people development — and why, despite that investment, they don't change.
