This book is not an analysis of Epicurean philosophy, but is rather a look at Epicurean philosophy in the historical context in which it was developed. I learned a lot about the development of the schools of Socrates, Plato, Aristotle and Epicurus and how they related to how Greece was changing politically at the time (and in the preceding decades/century). It helped me better understand why
Plato thought this, or Aristotle thought that. I really got a lot out of this book.
