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.
A bit like how George Harrison and Ringo Starr became so good because they were in the presence of Lennon and McCartney.
Being around great people and in that kind of environment is what leads to these kinds of breakthroughs.
Ringo Starr is often considered one of the great rock and roll drummers.
I'd like to think they all became so good partly because they were in the presence of each other.
