Unfortunately or otherwise, people are prone to believe in the reality of the things they think ought to be so. This comes of the cheery optimism which is innate with life itself; and, while it may sometimes be deplored, it must never be censured, for, as a rule, it is productive of more good than harm, and of about all the achievement there is in the world. There are cases where this optimism has been disastrous, as with the people who lived in Pompeii during its last quivering days; or with the aristocrats of the time of Louis XVI, fiwho confidently expected the Deluge to overwhelm their children, or their children's children, but never themselves. But there is small likelihood that the case of perverse optimism here to be considered will end in such disaster, while there is every reason to believe that the great change now manifesting itself in society will be as peaceful and orderly in its culmination as it is in its present development.
