The mares that carry me as far as longing can reach rode on, once they had come and fetched me onto the legendary road of the divinity, which carries the man who knows through every town. On this road I was carried.
Come now, I will tell thee (and do thou hearken to my saying and carry it away) the only two ways of search that can be thought of. The first, namely, that It Is, and that it is impossible for it not to be, is the way of conviction, for truth is its companion. The other, namely that It Is Not, and that something must needs Not Be, that, I tell thee, is a wholly untrustworthy path. For you cannot know what is not (that is impossible) nor utter it.
For it is the same thing that can be thought and that can be. What can be spoken and thought must Be.
