George Edward Moore 
Some Main Problems of Philosophy [PDF ebook] 

First published in 2002. This title collates a number of the late G. E. Moore’s lectures on philosophy with the inclusion of his audience’s questions and his answers that would bookend each session. Moore manages to present central, limiting, typical problems discussed in the study of philosophy in such a way that the reader begins to feel them despite themselves. Moore’s introduction to philosophical difficulties can help students and scholars alike to judge and understand the most modern attempts to resolve these problems.
