In this short book, Josef Pieper explains what happiness is and how it is attained. It may seem as an easy task, people have done it with a few sentences before, but as a philosopher Pieper have to complicate the matter. He draws mainly from Aristotle, Plato, Augustine and Aquinas, and it may seem like a limitation in choise as surley more people have written much about it - but it is in this vein of thinking that Pieper further explores the argument, it is the thinking that include God and that goes into the roots of the issue to find the ultimate truths behind the obvious, and then show how those thruths are the obvious conclusions that the arguments leads to. No wonder it ends close to where it began, in truths found with Aristotle and Aquinas, but it is the way there that is the interesting part of the book and that show how rich philosophy can be. After discussing happiness, he dwells on contemplation and kind of makes it more complex as a concept - this one has to bear in mind later something that I find somehat hard in books like this sometimes. In the end he ties it back to happiness again, just so that it feels like a whole.
