quoted from Nathan Sivin, On the Word "Taoist" as a Source of Perplexity. With Special Reference to the Relations of Science and Religion in Traditional China
>My point is a modest one, inspired by a saying of Confucius himself that can hardly be improved upon as a guide to critical research: "When you know something, to know that you know it; when you don't know it, to know that you don't know it: that's knowledge."
(Analects 2.17. Chih refers to understanding and recognition of significance as aspects of knowledge, not to objective factual knowledge isolated from the act of understanding and evaluating.)<
