Below I’ve listed many of the major works of philosophy, from those that require a lot of context to understand, to those that require very little. In addition, I’ve noted how difficult the texts might be for an amateur, which other philosophers you should be familiar with beforehand, and included a brief overview. The list is, of course, very incomplete, and additional suggestions are welcome.
A bunch of resources from the person who draws probably the most popular comic on philosophy.
