Speaking generally, our moral and practical attitude, at any given time, is always a resultant of two sets of forces within us, impulses pushing us one way and obstructions and inhibitions holding us back. “Yes! yes!” say the impulses; “No! no!” say the inhibitions. Few people who have not expressly reflected on the matter realize how constantly this factor of inhibition is upon us, how it contains and moulds us by its restrictive pressure almost as if we were fluids pent within the cavity of a jar. The influence is so incessant that it becomes subconscious. All of you, for example, sit here with a certain constraint at this moment, and entirely without express consciousness of the fact, because of the influence of the occasion. If left alone in the room, each of you would probably involuntarily rearrange himself, and make his attitude more “free and easy.” But proprieties and their inhibitions snap like cobwebs if any great emotional excitement supervenes. I have seen a dandy appear in the street with his face covered with shaving‐lather because a house across the way was on fire; and a woman will run among strangers in her nightgown if it be a question of saving her baby’s life or her own. Take a self‐ indulgent woman’s life in general. She will yield to every inhibition set by her disagreeable sensations, lie late in bed, live upon tea or bromides, keep indoors from the cold. Every difficulty finds her obedient to its “no.” But make a mother of her, and what have you? Possessed by maternal excitement, she now confronts wakefulness, weariness, and toil without an instant of hesitation or a word of complaint. The inhibitive power of pain over her is extinguished wherever the baby’s interests are at stake. The inconveniences which this creature occasions have become, as James Hinton says, the glowing heart of a great joy, and indeed are now the very conditions whereby the joy becomes most deep. This is an example of what you have already heard of as the “expulsive power of a higher affection.” But be the affection high or low, it makes no difference, so long as the excitement it brings be strong enough. In one of Henry Drummond’s discourses he tells of an inundation in India where an eminence with a bungalow upon it remained unsubmerged, and became the refuge of a number of wild animals and reptiles in addition to the human beings who were there. At a certain moment a royal Bengal tiger appeared swimming towards it, reached it, and lay panting like a dog upon the ground in the midst of the people, still possessed by such an agony of terror that one of the Englishmen could calmly step up with a rifle and blow out its brains. The tiger’s habitual ferocity was temporarily quelled by the emotion of fear, which became sovereign, and formed a new centre for his character.
