“But a man’s relationship to the world is determined not just by his intellect but by his feelings and by his who aggregate of spiritual forces. However much one implies or explains to a person that all that truly exists is no more than an idea, or that everything is made up of atoms, or that the essence of life is substance or will, or that heat, light, movement and electricity are only manifestations of one and the same energy; however much you explain this to a man—a being who feels, suffers, rejoices, fears and hopes—it will not explain his place in the universe.”
