The Problem With Philosophical Activity

Wittgenstein was not trying to build a system, at least I don't think he was here. There's nothing that you can do to empirically verify that principle. You can give no argument for the principle of verifiability except that it makes you comfortable because all the philosophical problems that worried you no longer have to think about it. And also there are things that have, like for instance, the concept of God fulfills some conceptual role may do so illegitimately but there's some motivation beyond a mere mistake and grammar.
