Though Liest, for the mark of Intelligence

To another philosopher it was said, “How “is it that thou dost condescend to learn from every “man?” He replied, “Because I know that learning is a “profitable thing come it from whatsoever source it may.”

Another philosopher whilst teaching his disciple said to him, “Dost thou understand?” and he replied, “Yes.” The philosopher then said, “Thou liest, for the mark of intelligence is the joy which sheweth itself in the disciple’s face, and not his answer “‘Yes’.”
