writing an essay on "Epicurus theory of Justice" ... below are Epicurus' Principal Doctrines:
31. The justice which arises from nature is a pledge of mutual advantage to restrain men from harming one another and save them from being harmed.
32. For all living things which have not been able to make compacts not to harm one another or be harmed, nothing ever is either just or unjust; and likewise too for all tribes of men which have been unable or unwilling to make compacts not to harm or be harmed.
33. Justice never is anything in itself, but in the dealings of men with one another in any place whatever and at any time it is a kind of compact not to harm or be harmed.
34. Injustice is not an evil in itself, but only in consequence of the fear which attaches to the apprehension of being unable to escape those appointed to punish such actions.
35. It is not possible for one who acts in secret contravention of the terms of the compact not to harm or be harmed, to be confident that he will escape detection, even if at present he escapes a thousand times. For up to the time of death it cannot be certain that he will indeed escape.
36. In its general aspect justice is the same for all, for it is a kind of mutual advantage in the dealings of men with one another: but with reference to the individual peculiarities of a country or any other circumstances the same thing does not turn out to be just for all.
37. Among actions which are sanctioned as just by law, that which is proved on examination to be of advantage in the requirements of men's dealings with one another, has the guarantee of justice, whether it is the same for all or not. But if a man makes a law and it does not turn out to lead to advantage in men's dealings with each other, then it no longer has the essential nature of justice. And even if the advantage in the matter of justice shifts from one side to the other, but for a while accords with the general concept, it is nonetheless just for that period in the eyes of those who do not confound themselves with empty sounds but look to the actual facts.
