The Natures of Things Cannot Be Determined

pyro seems in our passage to be laying down a bold philosophical thesis, namely that te natures of things cannot be determined. But this conviction is itself a belief. The second problem i want to mention is also one that confronted the later sceptics. We've understood pyro to be saying that he can do without any beliefs at all. In fact, his freedom from disturbance is achieved by giving up on the whole enterprise of forming beliefs. This, he has discovered, is the happy life. It doesn't even sound possible.
