The most interesting feature of history is how men have done things, wonderful things that subsequent generations are sure to admire and continue to admire whenever they have sense and training enough, yet forget about them. This is true not only for artistic productions but also for practical applications in science, for inventions, useful discoveries and the like. In surgery, for instance, though we have a continuous history of medicine, all of our instruments have been re-invented at least three or four times. After the reinvention we have been surprised to discover that previous generations had used these instruments long before us. Even the Suez Canal was undoubtedly open at least once before our time. Personally I feel sure that America was discovered at least twice before Columbus' time and that during several centuries there was considerable intercourse between Europe and America. It is extremely important for us then to realize these cycles in human progress and not to deceive ourselves with the idea that because we are doing something that immediately preceding generations knew nothing of, therefore we are doing something that never was done in the world before. This is particularly important for us now, for in my estimation the eighteenth was one of the lowest of centuries in human accomplishment, and therefore we may easily deceive ourselves as to our place in human history in this century. {58} Reflections of this kind are, it seems to me, particularly important for educators, especially in the midst of our tendency to accept evolution unthinkingly in this generation. Man's skull has not changed, his body has not been modified, his soft tissues are the same as they used to be. His brain is no different. Why, then, should he not have done things in the olden time just about as he does them now? We do not think that acquired characters are inherited. Oliver Wendell Holmes talks of Emerson as the seventh generation of an academic family, but there are none of us who think that this made it any easier for Emerson to acquire an education, or gave him a better development of mind. Those of us who have experience in education know that the descendant of a family of peasants for centuries or of farmers for many generations, easily outstrips some of the scions of academic families in intellect. It is the man that counts and not his descent.
