I have been wanting to read some classics of western literature from various disciplines. This level of reading is new to me and I feel it would be very beneficial to have solid introductions to what I am reading before just jumping in. I am talking about a pretty broad range of works from shake-spear to William James. My interest is just in self betterment and also to more fully appreciate and participate in the western intellectual tradition. Does anyone know of a good source online that walks people through this level of reading?
