This handbook contains the lives, writings, and doctrines of the Cyrenaic school by compiling together the primary sources of the material. It is not a summary or analysis of the Cyrenaic school. Rather it provides all of the (open and available) references to the Cyrenaic school within the ancient texts. Its main function is to put together in one place all of the disparate references spread across the Internet and libraries into one book. It is designed for the scholar and for the student. The scholar can use this resource to save time by having everything ready in one place. All references are taken from copyright-expired texts or open source (free) texts from places like Gutenberg and Archive.org. No copyrighted material is used in this book. All endnotes point to the source of each reference. The student of ancient philosophy will find this to be a starting point in their understanding of the Cyrenaic school. Many will undoubtedly use this book to aid their understanding of Hellenistic Philosophy and Epicureanism.
