To avoid pain we must know the conditions of health. For the accomplishment of this end we must rely upon investigation instead of faith, upon labor in place of prayer. Most misery is produced by ignorance. Passions sow the seeds of pain.

The old doctrine that God wanted man to do something for him, and that he kept a watchful eye upon all the children of men; that he rewarded the virtuous and punished the wicked, is gradually fading from the mind. We know that some of the worst men have what the world calls success. We know that some of the best men lie upon the straw of failure. We know that honesty goes hungry, while larceny sits at the banquet. We know that the vicious have every physical comfort, while the virtuous are often clad in rags.

When a man really believes that it is necessary to do a certain thing to be happy forever, or that a certain belief is necessary to ensure eternal joy, there is in that man no spirit of concession. He divides the whole world into saints and sinners, into believers and unbelievers, into God's sheep and Devil's goats, into people who will be glorified and people who are damned.
