Best place to start reading

[Dan Howard]

Reading original sources aren't much help unless you have training in source analysis. You need to understand the agenda of the author, any evident bias, translation problems, untangling and prioritising contradicitons, etc. A good secondary source can help cut through this but the problem is identifying a "good" secondary source. IMO the best approach is to read a good secondary source and whenever a primary source is cited, go and read that particular passage to see what it really says - ideally in the original language. Once you have a foundation in the subject then start reading the classics in their entirety.
