Wittgenstein's life is the subject of a great biography that offers many insights. However, the only criticism I have is the author's reluctance to explore his philosophy more deeply. Given that it is a biography, perhaps this isn't entirely unexpected. But when one considers that the book was almost 500 pages long, it's hard not to feel a little disappointed. After all, Wittgenstein was a truly incredible thinker of the 20th century, and his philosophy had a profound impact on many fields. Despite this criticism, the biography was still a great read. It provided detailed information about Wittgenstein's life, including his relationships, his work, and his personal struggles. It also gave a sense of the historical and cultural context in which he lived. Overall, it was a valuable contribution to the literature on Wittgenstein.
