Week by week

8 weeks, mapped out.

Here's the full arc of the module, week by week, so you know exactly what your family is signing up for.

I

Catching the Trick

Five common fallacies — ad hominem, straw man, false dichotomy, bandwagon, and appeal to emotion — as tricks to catch in real time, not a vocabulary list.

II

Valid or Just Loud?

The difference between a valid argument (the conclusion follows) and a sound one (valid, and the premises are actually true) — the most useful move in the whole course.

III

The Syllogism

Aristotle's three-line argument, 2,300 years old and still the same: a major premise, a minor premise, and a conclusion that follows of necessity.

IV

Two Ways of Knowing

Deductive reasoning (certainty from true premises) versus inductive reasoning (probability from evidence) — and why confusing the two is a quiet, serious error.

V

Prove It

The burden of proof belongs to whoever makes the claim — and why "you can't prove I'm wrong" is not evidence for anything.

VI

The Three Appeals

Aristotle's logos, pathos, and ethos, dissected in real ads — and the line between honest persuasion and manipulation.

VII

A Reason for the Hope

The Socratic method Jesus modeled — asking a real question instead of asserting a position — brings the course home to honest faith.

VIII

The Case

The capstone: research a genuinely contested question, build a fallacy-free case for both sides, and present it to someone who disagrees.

What you'll need

Supplies

  • A dedicated notebook (the "Logic Notebook")
  • A Bible
  • Index cards or slips of paper (Weeks 1 and 3)
  • Two or three short video ads cued up in advance (Week 6)
  • One other person willing to hold a real Socratic conversation or receive the Week 8 presentation

Most families already own these. A full printable list ships with the module.

Why it matters

Clear thinking is a form of obedience. Jesus commands us to love God with our minds, and Scripture anchors wisdom in the fear of the Lord — not raw intelligence. A person who reasons well is harder to deceive, more able to defend the truth, and better equipped to love a neighbor honestly. These eight weeks are not about winning arguments. They are about thinking the way a person of character thinks.
