This is a guide-book to joy. It is for the use of the sad, the bored, the tired, anxious, disheartened and disappointed. It is for the use of all those whose cup of vitality is not brimming over.
The world has not yet seen enough of joy. It bears the reputation of an elusive sprite with finger always at lip bidding farewell. In certain dark periods, especially in times of international warfare, it threatens to vanish altogether from the earth. It is then the first duty of all peaceful folk to find and hold fast to joy, keeping it in trust for their embattled brothers.
Even if this were not their duty as citizens of the world, it would be their duty as patriots. For Jean Finot is right in declaring that "people who are nobly happy constitute the power, the beauty and the foundation of the state."
This book is a manual of enthusiasm - the power which drives the world - and of those kinds of exuberance (physical, mental and spiritual) which can make every moment of every life worth living. It aims to show how to get the most joy not only from traveling hopefully toward one's goal, but also from the goal itself on arrival there. It urges sound business methods in conducting that supreme business, the investment of one's vitality.
It would show how one may find happiness all alone with his better self, his 'Auto-Comrade' - an accomplishment well-nigh lost in this crowded age. It would show how the gospel of exuberance, by offering the joys of hitherto unsuspected power to the artist and his audience, bids fair to lift the arts again to the lofty level of the Periclean age. It would show the so-called "common" man or woman how to develop that creative sympathy which may make him a 'master by proxy,' and thus let him know the conscious happiness of playing an essential part in the creation of works of genius. In short, the book tries to show how the cup of joy may not only be kept full for one's personal use, but may also be made hospitably to brim over for others.
