It is the same in all directions of life. There is always the desire to get near to those lives which have helped humanity in music, science, reform, philosophy, or religion. Whatever we know today is the result of thousands of years of experience. No country or nation can say, "We were the only discoverers of this, or that." No, the discovery of the very least thing is the discovery of the whole of humanity. How could we understand language, if we were not taught? Books, reading, civilization, seeing life, all have helped so much that no one can say that something is only due to a particular person or nation. The whole of humanity has shared in everything that we think new today.
