IRRITABILITY is, more than most unlovely states, a sin of the flesh. It is not, like envy, malice, spite, revenge, a vice which we may suppose to belong equally to an embodied or a disembodied spirit. In fact, it comes nearer to being physical depravity than anything I know of. There are some bodily states, some conditions of the nerves, such that we could not conceive of even an angelic spirit confined in a body thus disordered as being able to do any more than simply endure. It is a state of nervous torture; and the attacks which the wretched victim makes on others are as much a result of disease as the snapping and biting of a patient convulsed with hydrophobia. Then, again, there are other people who go through life loving and beloved, desired in every circle, held up in the Church as examples of the power of religion, who, after all, deserve no credit for these things. Their spirits are lodged in an animal nature so tranquil, so cheerful, all the sensations which come to them are so fresh and vigorous and pleasant, that they cannot help viewing the world charitably and seeing everything through a glorified medium. The ill-temper of others does not provoke them; perplexing business never sets their nerves to vibrating; and all their lives long they walk in the serene sunshine of perfect animal health. Look at Rover there. He is never nervous, never cross, never snaps or snarls, and is ready, the moment after the grossest affront, to wag the tail of forgiveness,--all because kind Nature has put his dog’s body together so that it always works harmoniously. If every person in the world were gifted with a stomach and nerves like his, it would be a far better and happier world, no doubt. The man said a good thing who made the remark, that the foundation of all intellectual and moral worth must be laid in a good healthy animal. Now I think it is undeniable that the peace and happiness of the home-circle are very generally much invaded by the recurrence in its members of these states of bodily irritability. Every person, if he thinks the matter over, will see that his condition in life, the character of his friends, his estimate of their virtues and failings, his hopes and expectations, are all very much modified by these things. Cannot we all remember going to bed as very ill-used, persecuted individuals, all whose friends were unreasonable, whose life was full of trials and crosses, and waking up on a bright bird-singing morning to find all these illusions gone with the fogs of the night? Our friends are nice people, after all; the little things that annoyed us look ridiculous by bright sunshine and we are fortunate individuals. The philosophy of life, then, as far as this matter is concerned, must consist of two things: first, to keep ourselves out of irritable bodily states; and, second, to understand and control these states, when we cannot ward them off.
