If so, which one? Early Wittgenstein or Late Wittgenstein or both! Two philosophers discuss these questions here, while the main case against both Wittgensteins is presented in summary fashion here. (Here is one morsel: “Wittgenstein’s reputation for genius did not depend on [his] incomprehensibility alone.”) On another note, below is a picture of Wittgenstein’s remote cabin in Norway (via Cabin Porn), where the great philosopher would spend his sabbaticals alone thinking important thoughts.
