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

Give me a chance to create a fever and I will cure any disease.

We can speak and think only of what exists. And what exists is uncreated and imperishable for it is whole and unchanging and complete. It was not or nor shall be different since it is now, all at once, one and continuous.

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.

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.

Gaze steadfastly at things which, though far away, are yet present to the mind.

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

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

Give me the power to produce fever and I’ll cure all disease.
