And, if one may remind you that the word is not the thing. The word 'tree' is not the actual tree, the word is not the thing; nor the description the described. One can describe the mountain, paint it, but the painting, the description is not the mountain. In exploring a very complex problem, one must have the capacity not only to use the word, the exact meaning of the word according to the dictionary, but also one must have the capacity and the quality of intensity to go beyond the word.
