Greek Philosophy: An Introduction (1924)
131 pages long. Divided into 20 short chapters.
The World's Manuals. "This little book is not intended for philosophers or for advanced students. It is an attempt to meet the need of a class of readers who have not hitherto received much consideration—men and women of average education who wish to know something about the aims of the Greek Philosophers and the substance of their teaching, but are repelled alike by the conciseness of the ordinary handbooks and by the length and difficulty of larger and more learned works."
