The Master said, "If one learns from others but does not think, one will be bewildered. If, on the other hand, one thinks but does not learn from others, one will be in peril." (Confucius, Analects 2.15; trans. D.C. Lau)
The point is you must learn, but must apply your learning from others, thereby multiplying knowledge through thinking. It seems, moreover, to be a conjunctive process that oscillates between learning and thinking and back again.
By the way, my more regular readership might want to know that the Analects resemble, at least formally, the Gospel of Thomas, in the sense of being a series of sayings that begin with "The Master said..." as Thomas begins each new saying with "Jesus said..." albeit with some variations (some sayings begin with a disciple's statement or question).
