There are three faculties in man, usually described as intellect, feeling and will. According as one or the other faculty predominates, we have a great scientist, a great poet, or a great moralist. We might choose a representative of each type--let us say Newton, Shakespeare and Jesus--and spend much time in controversy as to which of the three types is the greatest, which makes the greatest contribution to human happiness. But it will suffice here to point out that the three faculties do not exclude one another; every man must have all three, and a perfectly rounded man should seek to develop all three. Jesus was considerable of a poet, and we should pay far less heed to Shakespeare if he had not been a moralist. Also there have been instances of great poets and painters who were scientists--for example, Leonardo and Goethe. The fundamental difference between the scientist and the poet is that one is exploring nature and discovering things which actually exist, whereas the other is creating new life out of his own spirit. But the poet will find that his creations take but little hold upon life, if they are not guided and shaped by a deep understanding of life's fundamental nature and needs--in other words, if the poet is not something of a scientist. And in the same way, the very greatest discoveries of science seem to us like leaps of creative imagination; as if the mind had completed nature, through some intuitive and sympathetic understanding of what nature wished to be. The point about these higher forms of human activity is that they renew and multiply life. We may say that if Jesus had never lived, others would have embodied and set forth with equal poignancy the revolutionary idea of the equality of all men as children of one common father. And perhaps this is true; but we have no way of being sure that it is true, and as we look back upon the last nineteen hundred years of human history, we are unable to imagine just what the life of mankind during those centuries would have been if Jesus had died when he was a baby. We do not know what modern thought might have been without Kant, or what modern music might have been without Beethoven. We are forced to admit that if it had not been for the patient wisdom and persuasive kindness of Lincoln, the Slave Power might have won its independence, and America today might have been a military camp like Europe, and the lives and thoughts of every one of us would have been different.
