You must learn all things, both the unshaken heart of persuasive truth, and the opinions of mortals in which there is no true warranty.

The only roads of enquiry there are to think of: one, that it is and that it is not possible for it not to be, this is the path of persuasion (for truth is its companion); the other, that it is not and that it must not be - this I say to you is a path wholly unknowable.

For it is the same thing that can be thought and that can be.

It is indifferent to me where I am to begin, for there shall I return again.

Never will this prevail, that the things that are not are - bar your thought from this road of inquiry.

Do not let habit, born from experience, force you along this road, directing aimless eye and echoing ear and tongue; but judge by reason the much contested proof which I have spoken.

There is one story left, one road: that it is. And on this road there are very many signs that, being, is uncreated and imperishable, whole, unique, unwavering, and complete.
