I was wondering how to lay my hands on De Smet's piece on the Vakya (Sentence) as the determining factor in the diversity of interpretations of the Vedanta, and there it was: a part of the "Jaimini" article. Wonderful to find this. And very enlightening, though not at all simple!
As I read through the essays that are not strictly on Sankara, I begin to realize how much all this is important for an understanding of De Smet's interpretation of Sankara: Governing Principles of Indian Philosophy; Indian Contribution to General Metaphysics (1961); Patterns of Causality.
We might need a third volume of such essays. They are seminal.
