John Calvin, who made a theology for the seventeenth and eighteenth centuries, was tortured with disease for many years, and so was Robert Hall. The great men who have lifted the world to a higher level were not developed in easy circumstances, but were rocked in the cradle of difficulties and pillowed on hardships.

"The gods look on no grander sight than an honest man struggling with adversity."

"Then I must learn to sing better," said Anaximander, when told that the very boys laughed at his singing. Strong characters, like the palm-tree, seem to thrive best when most abused. Men who have stood up bravely under great misfortune for years are often unable to bear prosperity. Their good fortune takes the spring out of their energy, as the torrid zone enervates races accustomed to a vigorous climate. Some people never come to themselves until baffled, rebuffed, thwarted, defeated, crushed, in the opinion of those around them. Trials unlock their virtues; defeat is the threshold of their victory.

It is defeat that turns bone to flint; it is defeat that turns gristle to muscle; it is defeat that makes men invincible; it is defeat that has made those heroic natures that are now in the ascendency, and that has given the sweet law of liberty instead of the bitter law of oppression.

Difficulties call out great qualities, and make greatness possible. How many centuries of peace would have developed a Grant? Few knew Lincoln until the great weight of the war showed his character. A century of peace would never have produced a Bismarck. Perhaps Phillips and Garrison would never have been known to history had it not been for slavery.

"Will he not make a great painter?" was asked in regard to an artist fresh from his Italian tour. "No, never," replied Northcote. "Why not?" "Because he has an income of six thousand pounds a year." In the sunshine of wealth a man is, as a rule, warped too much to become an artist of high merit. A drenching shower of adversity would straighten his fibres out again. He should have some great thwarting difficulty to struggle against.

The best tools receive their temper from fire, their edge from grinding; the noblest characters are developed in a similar way. The harder the diamond, the more brilliant the lustre, and the greater the friction necessary to bring it out. Only its own dust is hard enough to make this most precious stone reveal its full beauty.

The spark in the flint would sleep forever but for friction; the fire in man would never blaze but for antagonism. The friction which retards a train upon the track, robbing the engine of a fourth of its power, is the very secret of locomotion. Oil the track, remove the friction, and the train will not move an inch. The moment man is relieved of opposition or friction, and the track of his life is oiled with inherited wealth or other aids, that moment he often ceases to struggle and therefore ceases to grow.

"It is this scantiness of means, this continual deficiency, this constant hitch, this perpetual struggle to keep the head above water and the wolf from the door, that keeps society from falling to pieces. Let every man have a few more dollars than he wants, and anarchy would follow."

Suddenly, with much jarring and jolting, an electric car came to a standstill just in front of a heavy truck that was headed in an opposite direction. The huge truck wheels were sliding uselessly round on the car tracks that were wet and slippery from rain. All the urging of the teamster and the straining of the horses in vain,—until the motorman quietly tossed a shovelful of sand on the track under the heavy wheels, then the truck lumbered on its way. "Friction is a very good thing," remarked a passenger.
