Philosophy of Science
One of the most provocative readings in philosophy is Wittgenstein's Tractatus. It however contains a lot of logical errors along with some interesting ideas. Therefore as stated elsewhere in this web the reader must read and re-think what has been read. Critical comments by me and spoted errors will be posted soon. My opinion is that despite of the fact that Wittgenstein tries to argue that unspeakable is a kind of non-sensical, he possibly sees that ontology of things cannot be said in words and so requires after reading the Tractatus one to throw it out as non-sensical itself. Well, my advice is the reader to be careful, and be warned that although Wittgenstein requires logically rigorous treatment (which is admirable idea), he himself made a lot of logical errors at many places. For example he is not aware of the problems of consistency of formal systems, and thinks that consistency is "obvious" and some things cannot even be imagined (e.g. 2.0121). Alas, this is not so, and became clear only a decade later when the work of Goedel on incompleteness of formal systems was published.
