If you google Aristotle on happiness you find: “according to Aristotle, the purpose and ultimate goal in life is to achieve eudaimonia (‘happiness’). He believed that eudaimonia was not simply virtue, nor pleasure, but rather it was the exercise of virtue.” As I understand St. Thomas Aquinas also agreed that the ultimate goal of life was happiness in this same vein. To that end I have 2 books t suggest on the subject of happiness:

“Peace of Soul” by Bishop Fulton J. Sheen is also good book to assist one searching for happiness. My copy was printed by Image books a Division of Doubleday & Company, Inc Garden City, New York, 1954

These next two books are more on the technical philosophical side but if you are intensely interested in happiness and how to best attain it and the depth involved to capture it completely. The first is a book authored by St. Thomas Aquinas entitled “Treatise on Happiness” and translated by John A Oesterle and the second is a commentary on it by J. Budzinszewski. They are technical philosophy and have no approbations

The final book I’m listing on happiness is one of the best book on I have seen on the faith, except for maybe The faith explained by Leo Trese (a book listed in the books on the catechism) in general and is entitled “Three Keys to Happiness” by fathers Edward and Paul Hayes. It was available on amazon which is where I ordered my second hand copy from.
