Kenneth Sylvan Launfal Guthrie (1871-1940), philosopher and writer, was a grandson of famous feminist pioneer Frances Wright and brother of William Norman Guthrie, a Scottish-born Episcopalian priest who issued a series of translations of ancient philosophical writers, "making available to the public the neglected treasures of Neo-platonism".
Among his works was a translation of the complete works of Plotinus (1918). He was also an active prohibitionist. In addition he composed music and wrote poetry. He has been described as a "brilliant but eccentric scholar" by Manly Palmer Hall.
As the title says it's a launching point into the philosophy of Plotinus. A very short and to the point book which gives bullet points and explanations to the key sections to Plotinus's philosophy. You glean enough to have an idea of what Plotinus had to say and perhaps develop the desire to jump into the Ennead and begin wading your way through it.
