"We must laugh and philosophize at the same time, and do our household duties, and employ our other faculties, and never cease proclaiming the sayings of the true philosophy." Epicurus VS41 (Bailey)
"For I would certainly prefer, as I study Nature, to announce frankly what is beneficial to all people, even if none agrees with me, rather than to compromise with common opinions, and thus reap the frequent praise of the many." - Epicurus VS29. (Bailey)
Boris Nikolsky is the author of the article "Epicurus on Pleasure" which explains that the kinetic / katastematic distinction was not of significance to Epicurus and was a much later non-Epicurean accretion.
"As many as possess the power to procure complete immunity from their neighbours, these also live most pleasantly with one another, since they have the most certain pledge of security, and, after they have enjoyed the fullest intimacy, they do not lament the previous departure of a dead friend, as though he were to be pitied." Epicurus PD40 (Bailey)
"The man who has best ordered the element of disquiet arising from external circumstances has made those things that he could akin to himself, and the rest at least not alien; but with all to which he could not do even this, he has refrained from mixing, and has expelled from his life all which it was of advantage to treat thus." Epicurus PD39 (Bailey)
Bailey: 38. Where, provided the circumstances have not been altered, actions which were considered just have been shown not to accord with the general concept, in actual practice, then they are not just. But where, when circumstances have changed, the same actions which were sanctioned as just no longer lead to advantage, they were just at the time, when they were of advantage for the dealings of fellow-citizens with one another, but subsequently they are no longer just, when no longer of advantage.
Bailey: 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.
Bailey: 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.
Bailey: 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.
