category of sensibility. Just as a bloodless organism can never, in spite of all its goodwill, attain to the reckless 'animal spirits' enjoyed by those of sanguine temperament; so the nature which is spiritually barren may admire and envy faith in others, but can never compass the enthusiasm and peace which those who are temperamentally qualified for faith enjoy. All this may, however, turn out eventually to have been a matter of temporary inhibition. Even late in life some thaw, some release may take place, some bolt be shot back in the barrenest breast, and the man's hard heart may soften and break into religious feeling. Such cases more than any others suggest the idea that sudden conversion is by miracle. So long as they exist, we must not imagine ourselves to deal with irretrievably fixed classes.
Now there are two forms of mental occurrence in human beings, which lead to a striking difference in the conversion process, a difference to which Professor Starbuck has called attention. You know how it is when you try to recollect a forgotten name. Usually you help the recall by working for it, by mentally running over the places, persons, and things with which the word was connected. But sometimes this effort fails: you feel then as if the harder you tried the less hope there would be, as though the name were jammed, and pressure in its direction only kept it all the more from rising. And then the opposite expedient often succeeds. Give up the effort entirely; think of something altogether different, and in half an hour the lost name comes sauntering into your mind, as Emerson says, as carelessly as if it had never been invited. Some hidden process was started in you by the effort, which went on after the effort ceased, and made the result come as if it came spontaneously.
