Kenneth Sylvan Launfal Guthrie (1871-1940), was a Scottish-born American philosopher, writer, and Episcopalian priest who issued a series of translations of ancient philosophical writers, "making available to the public the neglected treasures of Neo-platonism".
The works that he chose to translate are often very obscure. Few of them had ever been translated into English before; in many cases they have not been translated since. During his lifetime he was obliged to self-publish these books, and sell them by post in mimeographed form, often complaining of poverty and lack of recognition and support. Almost all of them have remained in print ever since.
