Thank you, gurugeorge! I will most certainly be looking into that.

That is so kind of you! Thank you :-) :-) :-)

O.k, then. You've been very helpful and I will most certainly look into your recommendations.

Thanks so much!

First of all - thanks again, to both of you, for the recommandations.

Please take into consideration the fact that I'm not looking for a book about Wittgenstein's life or the entirety of his works, but just a "targeted assault" on the Philosophical Investigations, perhaps, ideally, as cold and clinical in nature as the Investigations themselves.
Plus, please take into consideration the assumption that I "pretty much get it" and am looking for a more exhaustive "tractatus" of this work (not a "Wittgenstein for dummies" introduction books :-D ).

Considering those factors, do you stand behind those recommendations you've made?
