logic, explained simply
on this page
start here if logic is new to you
The rest of the reasoning section is a careful, grown-up reference — full of symbols like and words like antecedent. That’s great once you know your way around. This track is the on-ramp. No symbols required to start, and every idea comes with a story and a game.
You’ll learn how to:
- think clearly — break a tricky question into small, true-or-false pieces;
- win arguments fairly — and notice when someone is playing dirty;
- spot tricks — the sneaky moves that make a weak idea sound strong.
how each page works
Every “explained simply” page follows the same shape, so you always know what to expect:
- a story — a real situation you’ve probably been in;
- the idea — what’s really going on, in plain words;
- a picture — a diagram to make it click;
- spot it — where it shows up in real life;
- 🎮 you try it — a few quick puzzles (answers hidden until you peek);
- ⬆️ level up — a link to the full, grown-up page when you’re ready.
the pages
| start with | you’ll learn |
|---|---|
| if-then: the promise rule | the trickiest building block — when is an “if… then…” promise actually broken? |
| the straw man trick | the most common dirty move in any argument, and how to shut it down fairly |
(more coming — this track is growing.)
the big secret of logic
Most of logic is just this one move, over and over:
break a big, fuzzy question into small pieces that are each clearly true or false — then put the pieces back together with rules you can trust.
A computer does exactly this billions of times a second. A good detective, debater, scientist, or programmer does it too. Once you see it, you’ll spot it everywhere.
