Both combined are unequal to the task, and the daily life of man proves it so.
The Past! what a train of thought does it suggest! Aye, the Past, with its pleasures and misfortunes.

It haunts our consciences, and is ever before our eyes.

The murderer, though safely concealed from the world, and who may have escaped punishment by man for years, still has the Past to confront and harass his mind.

Penitence and prayer may lighten, but can never remove it.

Surrounded though he be with health and happiness, the demon of the Past will confront him ever, and make his life wretched.
