Neither the path of abstraction followed by the mystics, nor that of direct and, as it avers, unbiassed observation followed by the naturalists, can lead beyond that region of common experience, traditional feeling, and conventional thought which all minds enter at birth and can elude only at the risk of inward collapse and extinction. The fact that observation involves the senses, and the senses their organs, is one which a naturalist can hardly overlook; and when we add that logical habits, sanctioned by utility, are needed to interpret the data of sense, the humanity of science and all its constructions becomes clearer than day. Superstition itself could not be more human. The path of unbiassed observation is not a path away from conventional life; it is a progress in conventions. It improves human belief by increasing the proportion of two of its ingredients, attentive perception and practical calculus.
