🤔 What exactly is 'die Logik'?

Die Logik (feminine) generally refers to the study or science of rational and coherent thinking and reasoning. It's about how arguments are validly constructed and how one arrives at true conclusions from true premises.

It can also refer to:

• The coherence or internal consistency of an argument, plan, or action. Example: "Seine Argumentation fehlt jegliche Logik." (His line of reasoning lacks any logic.)
• A specific type of reasoning or a formal system. Example: mathematische Logik (mathematical logic), die Aussagenlogik (propositional logic).
• Colloquially, often simply for reason or common sense. Example: "Das widerspricht doch jeder Logik!" (That contradicts all logic!)

🚨 The word is almost exclusively used in the singular. The plural (die Logiken) is very rare and usually refers to different formal systems of logic.

😂 A Logical Joke

Ein Logikprofessor erklärt seinen Studenten: "Aus einer falschen Annahme kann man alles folgern! Zum Beispiel: Angenommen, 1 = 0. Addieren wir auf beiden Seiten 1, ergibt das 2 = 1. Nun bin ich der Professor und Sie sind der Student. Da 2 = 1, sind der Professor und der Student ein und dieselbe Person. Also sind Sie der Professor!"
Ein Student springt auf und ruft: "Fantastisch! Dann geben Sie mir bitte sofort Ihr Gehalt!"

Translation: A logic professor explains to his students: "From a false assumption, you can deduce anything! For example: Assume 1 = 0. If we add 1 to both sides, we get 2 = 1. Now, I am the professor and you are the student. Since 2 = 1, the professor and the student are one and the same person. Therefore, you are the professor!"
A student jumps up and shouts: "Fantastic! Then please give me your salary immediately!"

📜 A Poem about Logic

Die Logik, klar und rein,
lässt Schlüsse gültig sein.
Von A nach B, ein fester Schritt,
nimmt uns Verstand und Wahrheit mit.
Wo Chaos droht und Irrweg winkt,
die Logik Ordnung bringt.

Translation:
Logic, clear and pure,
lets conclusions be secure.
From A to B, a steady pace,
Reason and truth it does embrace.
Where chaos looms and error calls,
Logic brings order over walls.

❓ A Logic Riddle

Ich bin die Kunst des klaren Denkens,
des Argumentierens und des Lenkens.
Ich prüfe, ob ein Schluss auch stimmt,
damit die Wahrheit Oberhand gewinnt.
Philosophen schätzen meine Kraft,
auch Computer folgen mir ganzhaft.

Was bin ich?

Translation:
I am the art of thinking clear,
Of arguing and steering near.
I check if a conclusion's right,
So truth prevails with all its might.
Philosophers value my great strength,
Computers follow my whole length.

What am I?
