Fog-Free Logic

Somebody tries to convince you of something every single day. An advert, a headline, a
classmate, a person selling you a shortcut. Most of the time they are not lying. They are
giving you an ARGUMENT — and a bad argument that sounds good is far more dangerous than
a lie.

This book teaches you to take those arguments apart.

Sixty lessons. Each one starts with a scene where somebody is about to be fooled, then
asks you a question BEFORE any explanation is given — because trying and failing is what
makes the rule stick. Only then does the rule arrive, followed by two cases that look
identical but are not, a set of tasks, and a full solution that shows the reasoning
rather than just the answer.

WHAT IS INSIDE

• 60 lessons, each a self-contained two-page spread
• 517 questions and tasks, with 399 worked solutions
• 10 investigations and 5 mixed-practice workshops, where the tasks arrive out of order —
as they do in life
• A reference section: truth tables, the laws of thought, eight proofs taken apart step
by step
• A 71-entry glossary and a real bibliography
• A diagnostic before the first lesson, and the same questions at the end, so you can
measure what changed

WHO IT IS FOR

A thirteen-year-old who will be offered something stupid within the year, with a very
good explanation of why it is sensible. A teacher with no ready course. A parent who
argues with their child and loses while being right. And any adult who has ever walked
away from a conversation thinking: something was wrong there, and I could not name it.

WHAT IT DOES NOT DO

It does not tell you what to value or how to live. Logic checks whether one thing follows
from another; it does not decide what matters. That limit is stated openly in Lesson 59,
and it is the reason this book is not a sermon.

What it does is smaller and more useful: it takes the arguments away from whoever is
trying to fool you.

If, after this book, you stop just once and ask "what would change my mind?" — it has
paid for itself.
