What you think with, and how you argue.

logic
λογική · logikē
the art of the word-and-reason (logos)
Logos means, at once, word, account, reason, law. Logic is the craft of handling the word-and-thought rightly, and the same root ends the name of every discipline you study: bio-logy, psycho-logy, geo-logy. Whatever science you chose, you chose the Greek logos.

irony
εἰρωνεία · eirōneia
feigned ignorance
Eirōneia is the pose of knowing less than you do. It was Socrates' signature move: to ask innocent questions until the other man tangled himself in his own wisdom. The word for any sentence with a false bottom began as the name of one philosophical trap.

sarcasm
σαρκασμός · sarkasmos
the tearing of flesh (sarx)
Sarkazein in Greek means to tear flesh with the teeth, the way a dog rips its prey. That is what you do when you are sarcastic: you bite. The most polite form of cruelty carries a butcher's name.

category
κατηγορία · katēgoria
an accusation, a charge laid
Aristotle borrowed a courtroom word. Katēgoria is an accusation, the charge you lay against a defendant. He reworked it into a way of laying properties against the world, and now you pick a category in an app without hearing that you are charging someone.

energy
ἐνέργεια · energeia
being-at-work (en + ergon)
This word has an author. Aristotle forged energeia from en, 'in', and ergon, 'work', to name a thing that is acting rather than merely able to act. Every electricity bill is issued in a term one man invented in the fourth century BCE.

metaphysics
τὰ μετὰ τὰ φυσικά · ta meta ta physika
the [books] placed after the Physics
The grandest accident in the history of thought. When his students arranged Aristotle's works, the books on the first principles of being were shelved right after the books on nature, the 'physics'. The name of the deepest science is really a shelving note: the thing that stands after the Physics.

character
χαρακτήρ · charaktēr
an engraving stamp, a die
A charaktēr is the die that strikes a coin, and the mark it leaves. The Greeks named a person's temperament by that imprint, as if the soul had been stamped with a graver. Your character is what was pressed into you, caught in one exact word.

crisis
κρίσις · krisis
a judgement, a sifting
Krisis is the moment of judgement, when one thing must be sifted from another and a decision made. A physician called the crisis the day a disease turned toward life or death. Every crisis of yours is really a summons to court: the hour has come to sift and to choose.
Direct loan
ethics
ἠθική · ēthikē
the study of settled character (ēthos)
Ēthos is settled character, the soul's ingrained habit, the path it has worn. Ethics studies the groove those acts wear more than it studies the single acts. When Cicero rendered the word into Latin he coined moralis, and so we received a second, Latin name for the very same thing.

atom
ἄτομος · atomos
the uncuttable (a + tomos)
Democritus imagined that cutting a thing cannot go on forever: at the end lies the atomos, 'the uncuttable'. Twenty-four centuries later we split the uncuttable in two and kept its old name. The name of the world's smallest brick is a promise we broke.
NodeAtomism →Direct loan
idea
ἰδέα · idea
a thing seen (from idein, to see)
Plato's idea comes from idein, 'to see'. An idea is the look of a thing, its face, beheld by the mind rather than the eye. When an idea 'comes to you', in Greek you have just seen something.
NodeThe Forms →Direct loan
philosophy
φιλοσοφία · philosophia
love of wisdom (philia + sophia)
Tradition credits the word to Pythagoras: he refused, so the story goes, to be called a sage, a sophos, and named himself only a philosophos, a lover of wisdom rather than its owner. Historians doubt it happened that way. The modesty stayed inside the word regardless: a philosopher is a lifelong suitor of a truth he never quite matches.

aesthetics
αἴσθησις · aisthēsis
sense perception
Aisthēsis is what reaches you through eyes, ears and skin. 'Aesthetics' was minted in the eighteenth century from this root as the science of sense knowledge – and only later narrowed into talk about beauty. Anaesthesia is its blood sister: aisthēsis switched off.

problem
πρόβλημα · problēma
a thing thrown forward (pro + ballō)
Problēma is literally 'a thing thrown forward': the Greeks used it for a headland that blocks a sailor's course and for a shield held out before the body. The geometers then laid it on the tasks set before a student. Your 'we have a problem' is still honest: something lies across the road and will have to be moved.
Direct loan
method
μέθοδος · methodos
the way along, a pursuit (meta + hodos)
Hodos is a road; methodos is the way you take after something, a pursuit along a track. For a Greek a method was the road thought walks to its goal step by step, instead of wandering. Descartes titled his most famous book a Discourse on the Method – on how to lay such a road for any mind.
NodeMethodic Doubt →Direct loan
criticism
κριτική · kritikē
the art of judging and sifting (from krinō)
The same root as 'crisis' and 'criterion': krinō, to sift grain from chaff, to judge. A critic is by trade a judge who sifts. Kant raised the word into the titles of his major books: the Critique of Pure Reason is a trial to which reason summons itself.
Direct loan
fantasy
φαντασία · phantasia
an appearing, an image (from phainō, to show)
Phainō means 'to bring into the light'; phantasia is what appears before the inner eye. In Aristotle it is a technical term: the soul's power to hold the image of a thing after the thing itself is gone. 'Phantom' grows from the same root, so your fantasy is, in Greek, a workshop of apparitions.
Direct loan
organ
ὄργανον · organon
a tool, an instrument (from ergon, work)
An organon is a tool, and its root is the same ergon, 'work', that sits inside 'energy'. Aristotle called the hand the tool of tools, and his logical treatises were gathered by his followers under the title Organon – the instrument of thinking. The organ in your chest and the organ in a cathedral are still one word: an instrument that does work.

eureka
εὕρηκα · heurēka
I have found it (from heuriskō)
The tale comes from Vitruvius: Archimedes, lowering himself into a bath, saw the answer to the crown problem and ran through the city naked, shouting heurēka – 'I have found it!'. The story was written down two centuries later, so the run may be invention; the verb is real. From the same root comes heuristics, the science of how things get found.
