Why are you assuming that people haven't tried? When I went to university in Germany, Wittgenstein and Adorno were cult figures.

People were reading their works because it was fashionable (yes, hard-copy, cover to cover). I did, too. Now I think it was a waste of time.

The Tractatus is an unordered collection of pretty mundane observations which do not inspire any useful thought.

And the Tractatus was the work with the highest cult status.
