ABSTRACT
Inborn Connections. — Every educated person knows that some sort of connection exists between events taking place in the physical world and his mental states; that he hears sounds because there are sound-waves, and smells odors when certain gases are present in the atmosphere. The immediate connection is between the action of neurones in the brain and the mental states; but since these neurones are aroused to action by afferent neurones from the sense organs, and since these afferent neurones are aroused by the physical event either directly or through some physiological process, we commonly speak of the total series of connections between the physical event and the mental state as one connection.
