The most alert and indispensable of endowments, it is at once sociable with the remainder of man’s faculties, external and internal, and jealously independent of them saving of human consciousness alone. In its higher stages of development it accepts suggestions from all, dictation from none. Its manner is courteous and its mode of approach one of promptings and hints. The sphere of every other faculty is its sphere where it is content to play the modest part of a handmaiden, never usurping functions already provided for, although it has a sphere of its own whither not even reason can follow. It is supplementary to all, contradictory to none. Without its exercise there can be no progress or growth. It has its origin in a groping instinct, its final development in orderly activities capable of increasingly clear classification. Body, intellect, character, moral and religious, are under its influence and dependent upon its beneficent operations. It plays upon the body, contributing to its health and efficiency; it gives wings to the intellect, making it creative and productive, capable of formulating hypotheses and venturing upon speculation; it converts the seemingly impossible into the normal, bringing moral ideals within reach of the will, without which improvement in character would be a matter of chance; it unfolds the Divine to the human and forms a nexus between here and beyond, now and to-morrow, finite and infinite, God and man. It looks not only up but down, making the nature outside of us intelligible to the nature inside of us and friendly with it. If it peoples the stars, it also makes a universe of the atom. It is mysterious, recollective, emotional, intuitive, speculative, imaginative, prophetic, minatory, expectant, penetrative. As it moves up or down with equal freedom, so it reaches backward or forward, is attached or detached at will, in its operations. The Sixth Sense, or, to be more accurate, the second group of senses, has its specialized functions, difficult as it is to analyze with accuracy this most spiritual endowment of human personality, the inner gift of touch. It has specializations parallel to those of the bodily senses. Sight, hearing and testing are its functions. So clear eyed is it that it can see with the nicety of an eye aided by the microscope, so sensitive to voices that the lowest whispers impart a message, so critical as to test values with a precision and swiftness that surpass the taste and smell which tell us what is sweet and what unsavory. If it be argued that I am but dilating on certain aspects of mind, I am not concerned to deny that all may be comprehended under that convenient blanket-word. But they are as distinct from the rationalizing media as from the will.
