Debate ethics, name the fallacy, and hold a big-ideas conversation — out loud, in Spanish.
Spanish keeps la ética and la moral distinct — and using them precisely is what separates philosophical Spanish from opinion-swapping. The single most useful debate phrase is eso es una falacia: it's the standard accusation in Spanish-language arguments online, alongside normalized latinisms like ad hominem. Structure an argument as premise → reasoning → conclusion: la premisa, la deducción, and when you take one apart, la refutación. And know the register split — la angustia existencial is the formal term, but at an Argentine dinner table it's just crisis existencial, almost a cliché.
Below: the ethics, logic and existentialism vocabulary lesson by lesson, how it sounds in everyday debate, and a way to learn it with no flashcards — every term earned by saying it in a live discussion.

Your vocabulary teacher for this pack
No flashcards, no fill-in-the-blanks — in the Deep Thinker lessons you argue, and Olivia feeds you the exact word the moment your position needs it. One lesson is an ethics seminar: the trolley problem, and you defending a side with el utilitarismo against la deontología. Another is a logic workshop where she slips fallacies into her own reasoning and waits — eso es una falacia — for you to catch them. Then a reading group on existentialism: el absurdo, el libre albedrío, and whether todo está escrito. Out loud, until abstract stops meaning unspeakable.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
Philosophically, la ética is the study, la moral the lived code — and educated Spanish keeps them apart. In everyday Mexican debate it flattens to ¿es ético o no?, while el dilema moral has crossed from academia into ordinary Argentine speech.
La falacia lógica — and eso es una falacia is the go-to accusation in social-media debates. Latinisms are fully normalized: ad hominem in Colombian press and forums, and Spain's translated anglicism hombre de paja for a straw man.
El libre albedrío — a genuine dinner-table and press debate across the Spanish-speaking world. Its determinist counterpart shows up colloquially in Mexico as todo está escrito, the everyday voice of el determinismo.
Crisis existencial — so common in Argentina it's nearly a cliché. Mexicans say tener un bajón existencial for the low moment; the formal philosophical term behind both is la angustia existencial.
The load-bearing set: la ontología, la epistemología, la dialéctica, la paradoja, el relativismo, la cosmovisión. Watch the tone of pura dialéctica in the Southern Cone — it can be dismissive, an argument going nowhere — and todo es relativo is the sobremesa cliché, not a position.
