One idea from a book. The line, and when to use it.

“33. “Natural justice is a covenant of what is suitable, leading men to avoid injuring one another, and being injured. [...] 35. “Justice has no independent existence; it results from mutual contracts, and establishes itself wherever there is a mutual engagement to guard against doing or sustaining mutual injury. 36. “Injustice is not intrinsically bad; it has this character only because there is joined with it a fear of not escaping those who are appointed to punish actions marked with that character. 37. “It is not possible for a man who secretly does anything in contravention of the agreement which men have made with one another, to guard against doing, or sustaining mutual injury, to believe that he shall always escape notice, even if he have escaped notice already ten thousand times; for, till his death, it is uncertain whether he will not be detected. [...] 41. “[...] when in consequence of new circumstances, a thing which has been pronounced just does not any longer appear to agree with utility, the thing which was just, inasmuch as it was useful to the social relations and intercourse of mankind, ceases to be just the moment when it ceases to be useful.” — Diogenes Laertius, *Lives of Eminent Philosophers*, Book X, Sec. XXXI, Maxims 33, 35–37, 41, trans. C. D. Yonge (1853). **Surface Gloss:** Justice is not an eternal entity; it is a local non-aggression treaty. Breaking it in secret is foolish only because lifelong fear of exposure ruins peace of mind, and any law stops being just the exact moment it stops being useful. Two linked mechanisms: 1. **The Sunset Clause of Rules (Maxim 41):** Never defend a legacy policy, process, or norm by claiming it was "always wrong" or "always right." Acknowledge that it *was* valid when it served mutual utility, and declare it dead the exact second environmental shifts erase that utility. 2. **The Gyges Paranoia Tax (Maxim 37):** Never take a covert shortcut whose value depends on permanent non-detection. Even a 99.9% chance of staying hidden charges an ongoing cognitive tax ("will today be the day?") that costs more than the illicit gain.

“30. “Of the desires, some are natural and necessary, some natural, but not necessary, and some are neither natural nor necessary, but owe their existence to vain opinions.” (Epicurus thinks that those are natural and necessary which put an end to pains, as drink when one is thirsty; and that those are natural but not necessary which only diversify pleasure, but do not remove pain, such as expensive food; and that these are neither natural nor necessary, which are such as crowns, or the erection of statues.) 31. “Those desires which do not lead to pain, if they are not satisfied, are not necessary. It is easy to impose silence on them when they appear difficult to gratify, or likely to produce injury. 32. “When the natural desires, the failing to satisfy which is, nevertheless, not painful, are violent and obstinate, it is a proof that there is an admixture of vain opinion in them; for then energy does not arise from their own nature, but from the vain opinions of men.” — Diogenes Laertius, *Lives of Eminent Philosophers*, Book X, Sec. XXXI, Maxims 30–32, trans. C. D. Yonge (1853). **Surface Gloss:** Desires split into three classes: natural-necessary (ending pain), natural-unnecessary (merely varying pleasure), and unnatural-unnecessary (status symbols). When a non-painful natural desire feels violent and obsessive, its heat comes from corrupted social opinion, not nature. The **Obsession Diagnostic**: how do you tell whether an intense craving (for a specific hire, a luxury acquisition, a romantic target, or a market win) is a real structural need or an ego-hallucination? Run the two-step Epicurean test: First, if I walk away right now, does it cause actual structural damage ("pain"), or just a missed variation? Second, if it causes no structural damage yet my craving feels "violent and obstinate," the energy driving me is 100% synthetic narrative ("vain opinion") — not the thing itself.

“10. “If apprehensions relating to the heavenly bodies did not disturb us, and if the terrors of death have no concern with us, and if we had the courage to contemplate the boundaries of pain and of the desires, we should have no need of physiological studies. 11. “It would not be possible for a person to banish all fear about those things which are called most essential, unless he knew what is the nature of the universe, or if he had any idea that the fables told about it could be true; and therefore, it is, that a person cannot enjoy unmixed pleasure without physiological knowledge. 12. “It would be no good for a man to secure himself safety as far as men are concerned, while in a state of apprehension as to all the heavenly bodies, and those under the earth, and in short, all those in the infinite.” — Diogenes Laertius, *Lives of Eminent Philosophers*, Book X, Sec. XXXI, Maxims 10–12, trans. C. D. Yonge (1853). **Surface Gloss:** Studying natural science has zero intrinsic value; we only need to understand the physical mechanics of the cosmos because otherwise mythic fables about the sky and the underworld will poison our peace of mind. The **Therapeutic Minimum of Research**: never build an explanatory model deeper than the specific anxiety or operational risk it is meant to neutralize. Before sinking months into mapping a complex system ("physiological studies"), ask what concrete fear or failure mode that knowledge eliminates. If a black-box system poses no threat to your execution and you already know the boundaries of your own needs, deep-diving its internal mechanics is intellectual procrastination disguised as rigor.

“1. “That which is happy and imperishable, neither has trouble itself, nor does it cause it to anything; so that it is not subject to the feelings of either anger or gratitude; for these feelings only exist in what is weak. [...] 2. “Death is nothing to us; for that which is dissolved is devoid of sensation, and that which is devoid of sensation is nothing to us. 3. “The limit of the greatness of the pleasures is the removal of everything which can give pain. And where pleasure is, as long as it lasts, that which gives pain, or that which feels pain, or both of them, are absent. 4. “Pain does not abide continuously in the flesh, but in its extremity it is present only a very short time. That pain which only just exceeds the pleasure in the flesh, does not last many days. But long diseases have in them more that is pleasant than painful to the flesh.” — Diogenes Laertius, *Lives of Eminent Philosophers*, Book X, Sec. XXXI, Maxims 1–4, trans. C. D. Yonge (1853). **Surface Gloss:** Perfected beings neither feel anger nor grant favors; death is non-experience; maximum pleasure is simply the complete absence of pain; and bodily pain is either brief in its extremity or mild in its duration. The **Zero-State Ceiling**: most human misery comes from treating satisfaction as an open-ended vertical ladder when it is actually a binary pressure-valve. Once structural deficit (pain, hunger, acute threat) is removed, you are already at 100% baseline capacity. Everything beyond that zero-deficit mark is merely horizontal flavor-swapping ("diversification"), not an increase in well-being. Stop paying exponential effort costs for horizontal variety under the delusion that it raises your vertical ceiling.

And we must consider that some of the passions are natural, and some empty; and of the natural ones some are necessary, and some merely natural. And of the necessary ones some are necessary to happiness, and others, with regard to the exemption of the body, from trouble; and others with respect to living itself; for a correct theory, with regard to these things, can refer all choice and avoidance to the health of the body and the freedom from disquietude of the soul. Since this is the end of living happily; for it is for the sake of this that we do everything, wishing to avoid grief and fear; and when once this is the case, with respect to us, then the storm of the soul is, as I may say, put an end to... When, therefore, we say that pleasure is a chief good, we are not speaking of the pleasures of the debauched man, or those which lie in sensual enjoyment, as some think who are ignorant, and who do not entertain our opinions, or else interpret them perversely; but we mean the freedom of the body from pain, and of the soul from confusion. — Diogenes Laertius, *Lives of Eminent Philosophers*, Book X, Section XXVII (Epicurus, *Letter to Menoeceus*), trans. C. D. Yonge (1853). **Surface Gloss:** Writing to Menoeceus, Epicurus classifies desires into natural-necessary, merely natural, and empty, defining supreme pleasure not as sensual indulgence, but as the zero-state where bodily pain and mental turmoil are completely removed. **The Katastematic Ceiling & Desire Audit:** Run every goal, purchase, or ambition through Epicurus's three-bucket filter: 1. Does failing to get this cause actual physical or existential pain? (*Natural + Necessary* — secure immediately at lowest cost). 2. Does it merely vary the flavor of an already pain-free state without raising the ceiling? (*Natural + Non-Necessary* — enjoy when free, drop instantly when expensive). 3. Is its intensity driven entirely by status-narrative and "vain opinion"? (*Empty* — kill on sight). Remember the ceiling law: once friction and want are at zero, you are already at maximum altitude; expensive additions only change the wallpaper.

We cannot act in the same way with respect to the heavenly phænomena: these productions may depend upon several different causes, and we may give many different explanations on this subject, equally agreeing with the impressions of the senses. Besides, it is not here a question about reasoning on new principles, and of laying down, _à priori_, rules for the interpretation of nature; the only guides for us to follow are the appearances themselves; for that which we have in view is not a set of systems and vain opinions, but much rather a life exempt from every kind of disquietude. ... The eclipses of the sun and moon may depend either on the fact that these stars extinguish themselves, a phænomenon which we often see produced under our eyes, or on the fact of other bodies, the earth, the heaven, or something else of the same kind interposing, between them and us. ... As to those who on this point admit only one explanation as possible, they put themselves in opposition to facts, and lose sight of the bounds set to human knowledge. — Diogenes Laertius, *Lives of Eminent Philosophers*, Book X, Section XXV (Epicurus, *Letter to Pythocles*), trans. C. D. Yonge (1853). **Surface Gloss:** Writing to Pythocles, Epicurus rules that while fundamental physics has single necessary truths, distant sky-events must be explained by multiple simultaneous hypotheses drawn from everyday analogies; insisting on a single cause where we cannot get close enough to verify is vain dogmatism that breeds anxiety. **The Anti-Mythology Portfolio (Pleonachos Tropos):** When an opaque, distant event occurs (a competitor’s sudden pivot, a market crash, a senior executive's silence) where you cannot get close-range verification, the human brain defaults to *monachos tropos*: locking onto a single dramatic explanation (usually attributing godlike intent or malice to the actor) and panicking over it. Break the spell by forcing yourself to list **four distinct, mundane, mechanical explanations** drawn from everyday analogies that all fit the visible facts, and hold all four open at equal weight. The moment you refuse to crown a single story, the superstitious anxiety evaporates.

Treating words as opaque symbols is the wrong assumption for morphologically complex languages. Encoding morphology into three model types — a Bayesian compound-decomposition n-gram model, a distributed model learning vector representations of morphemes, and an unsupervised model that discovers even discontiguous (Semitic-style) morphemes — improves model performance and beats the data sparsity that morphological processes create, with benefits for machine translation.

Don't model the surface — learn the substructure; the regularities that fix sparsity live inside the unit everyone treats as atomic.

The U.S.-centric counter-nuclear-smuggling network in Europe (CNS-E) is "highly decentralized and dense" — cooperation is abundant but not strong enough to ensure information actually gets shared. The fixes: strengthen existing relations instead of creating new ones, centralize capabilities and information in regional hubs, get SOCOM tied to law enforcement, and run threat assessments of European CBRN facilities.

Strengthen existing ties before adding new ones — in a network that must act fast, weak ties don't move information, no matter how many there are.

A carrier strike group's deterrence value can be quantified with a Markov-game model: in the South China Sea case study (U.S. as global power, China as regional power), the two players deploy limited forces and compete for alliances among the Philippines, Vietnam, Taiwan, Singapore, Indonesia, and Malaysia — deterrence emerges from the alliance competition inside the DIME (diplomatic, information, military, economic) construct, not from hull counts alone.

Deterrence is a game, not a fleet count — model the alliance competition, not just the hulls, when asking what a carrier deployment is worth.

The sponsor-affiliate (patron-proxy) relationship is won or lost on "client management": the IRGC held 35 years of influence over SCIRI, the Badr Corps, and the militias that descended from Badr in Iraqi politics by building trusted agents during a formative period of tight control and integration in the Iran-Iraq War, then placing those agents at the head of new organizations after Badr returned to Iraq.

Manage the client before you arm it — lasting proxy influence comes from trusted agents planted during a period of tight control, not from the weapons supplied later.

In metagenomic read classification, spaced seeds (k-mers with wildcard positions) beat traditional contiguous k-mers — but with an explicit operating envelope: the advantage holds below ~0.9 sequence identity; for very high-quality alignments (identity ~0.95+) contiguous k-mers with hit-number scoring win. Jaccard-index scoring amplifies the spaced-seed advantage for small-weight seeds.

Every method has an operating envelope — spaced seeds win at low identity, contiguous k-mers at high identity; the honest answer is a switch, not a champion.

Literature screening plus ENVI-met microclimate simulations on a Brno case site (Římské náměstí) show targeted nature-based solutions — trees and hedges, permeable green surfaces, green walls first — can significantly mitigate the urban heat island even under challenging climatic variability, with final-design air temperatures and UTCI values compared against both current and rural baselines.
