Heidegger is notoriously difficult, but once you decode him he is easy and there is a huge payoff. The following is more or less what I did.
I did some study notes on Heidegger that some might find helpful.
a) Jamie Smith’s *Desiring the Kingdom,* despite all of Smith’s goofiness, does a good job explaining what Heidegger was about.
b) I read Heidegger’s *Basic Writings* first. The upshot is that you get a glimpse of his finest writing. The downside is you really don’t understand his project until you read Being and Time.
c) My intellectual mentor, Matthew Raphael Johnson, has a good lecture on Heidegger.
d) The world-class British orator Jonathan Bowden did an outstanding lecture on Heidegger. He places Heidegger as the counter-opposite of Satre
Merold Westphal has a good introductory lecture. Here is a course he did. The audio is awful, but you might be able to make something out of it.
