It is obvious that the feelings attributed to other men are nothing but the tertiary qualities of their bodies. In beings of the same species, however, these qualities are naturally exceedingly numerous, variable, and precise. Nature has made man man’s constant study. His thought, from infancy to the drawing up of his last will and testament, is busy about his neighbour. A smile makes a child happy; a caress, a moment’s sympathetic attention, wins a heart and gives the friend’s presence a voluminous and poignant value. In youth all seems lost in losing a friend. For the tertiary values, the emotions attached to a given image, the moral effluence emanating from it, pervade the whole present world. The sense of union, though momentary, is the same that later returns to the lover or the mystic, when he feels he has plucked the heart of life’s mystery and penetrated to the peaceful centre of things. What the mystic beholds in his ecstasy and loses in his moments of dryness, what the lover pursues and adores, what the child cries for when left alone, is much more a spirit, a person, a haunting mind, than a set of visual sensations; yet the visual sensations are connected inextricably with that spirit, else the spirit would not withdraw when the sensations failed. We are not dealing with an articulate mind whose possessions are discriminated and distributed into a mastered world where everything has its department, its special relations, its limited importance; we are dealing with a mind all pulp, all confusion, keenly sensitive to passing influences and reacting on them massively and without reserve.
