Abstract
Perhaps we can say that the book has had a "negative" influence; the mistakes of the Tractatus have helped us to become clearer about the correct way of philosophizing. The difficulty with this view is that many of the criticisms of the Tractatus have been wide of the mark. In denying the influence of the Tractatus, I do not intend to slight its importance. On the contrary, we must distinguish the Tractatus from both logical positivism and Russell's logical atomism, as well as from the subsequent criticisms of these positions, if we are to understand and appreciate it.
