Yeah, the 'later' Wittgenstein actually throws away a lot of his 'early' Wittgenstein and he actually admits that his quest for absolute undivisible logic was actually a bit embarrassing.

The importance of his later works Philosophical Investigations seems to be underlooked in the article in favor of his earlier Tractatus, which is a bit sad. Wittgenstein's later work, although fiercely criticized by rigid supporters of logical atomism (such as Russell), seem to have contributed much more to the advancement of philosophy in overall.
