And they lay down the position that all offences are equal, as Chrysippus argues in the fourth book of his Ethic Questions, and so say Persæus and Zeno. For if one thing that is true is not more true than another thing that is true, neither is one thing that is false more false than another thing that is false; so too, one deceit is not greater than another, nor one sin than another. For the man who is a hundred furlongs from Canopus, and the man who is only one, are both equally not in Canopus; and so too, he who commits a greater sin, and he who commits a less, are both equally not in the right path... And they say, that not only are the wise free, but that they are also kings, since kingly power is an irresponsible dominion, which can only exist in the case of the wise man... Another doctrine of the Stoics is, that there is nothing intermediate between virtue and vice... For the Stoics say, that as a stick must be either straight or crooked, so a man must be either just or unjust, and cannot be more just than just, or more unjust than unjust; and that the same rule applies to all cases. — Diogenes Laertius, *Lives*, VII.64–65 (tr. C. D. Yonge, 1853) **Surface Gloss:** Because virtue is an all-or-nothing structural perfection like a straight stick or being inside the city of Canopus, all sins are equally outside the mark, and only the wise man is truly free, sane, and a king. Know when a problem is governed by **analog progress** (getting closer to Canopus matters) versus **binary threshold** (being *inside* Canopus, or a stick being straight). In engineering, security, and personal integrity, a bridge that is 99% structurally sound or a cryptographic key that is 99% secure is 100% compromised. Use the Canopus test to kill moral complacency: *"Closer to the gate is good for the march, but until we are inside the wall, we are still outside in the desert."*
