In approaching the problem of incontinence it is a good idea to dwell on the cases where morality simply doesn’t enter the picture as one of the contestants for our favour—or if it does, it is on the wrong side. Then we shall not succumb to the temptation to reduce incontinence to such special cases as being overcome by the beast in us, or of failing to heed the call of duty, or of succumbing to temptation.
