Here I must answer an objection which may be raised--namely, that Natural Beauty is the concern of Aesthetics, not of Geography. An objector may freely acknowledge the value and importance of recognising and describing the Natural Beauty of a country, but may contend that this is beyond the province of Geography. It should be left to poets and painters, he might say, and geographers should confine themselves to the more prosaic business of exact measurement, of accurate delineation, of reasoning regarding the relation of the facts to one another, and of explaining the facts. To such an objector I would reply that Geography is an art as well as a science. And in parenthesis I may say that I doubt whether any science can be complete which has not art behind it. We shall never be able fully to know and understand the Earth or to describe what we see if we use our intellectual and reasoning powers alone. If we are to attain to a complete knowledge of the Earth, and if we are to describe what we learn about it in an adequate manner so that others may participate in our knowledge, then we must use our hearts as well as our heads. We must be artists as well as meticulous classifiers, cataloguers, and reasoners. The Earth is a living being, a throbbing, palpitating, living being--"live" enough to have given birth to the remote ancestors of mankind, and live enough, so some biologists consider, to be continually to this day generating the lowliest forms of organisms. To know and understand a living being, particularly when that living being happens to be his own Mother, man must use his heart as well as his head. With his head alone the geographer may do a vast amount of most useful and necessary work which will help us to understand the Earth. He may collect and classify facts about her and record measurements, and reason about these facts and measurements, but if he is to get the deepest vision of the Earth and learn the profoundest truth about her he must exercise his finest spiritual senses as well. And when he brings those faculties of the soul into play, it will be the Beauty on the face of Mother-Earth that he will see and that will disclose to him her real nature. And therefore I hold that if it be the function of Geography to know the Earth and to describe the Earth, then the objection that the description of its Natural Beauty is outside the scope of Geography is not a valid objection. The picture and the poem are as legitimate a part of Geography as the map.
