This isn't really how most people should read books. You aren't reading a book to learn arguments like a parrot. The meaning of all the books he mentions has changed over time, and you won't have the same understanding the second time you read it (i.e. years after, re-reading it straight after is pointless...it is robotic).

Also, just generally I think the structure of the course is bad. Reading three books cover-to-cover is basically pointless (Keynes esp. so as it was a textbook, I think he would turn in his grave if he thought people were being subjected to this, both Marx/Smith are very dry in areas too). It would be far better to look at the key ideas across more periods and get students to engage directly with those ideas...which is why similar courses in philosophy, theology, etc. do this.
