It's the tool for learning how to use other tools.

It's the bones that give a clenched fist its structure (and knuckles).

Introductory Logic is perfect for Grade 7+ students, teachers, and parents who've never tackled syllogisms or fallacies before. It provides a semester or year's worth of logic to help you detect and deflect flawed or deceitful arguments and to think, debate, and argue well.

Lesson Scope of Introductory Logic

• Introductory Logic helps you
• Control the debate by defining your terms, because “He who defines the terms wins the debate.” (Unit 1—Terms and Definitions)
• Think logically when you can write true and false statements. (Unit 2—Statements and Their Relationships)
• Disprove invalid arguments when you know the rules of a valid argument. (Unit 3—Syllogisms and Validity)
• Interpret and expose an argument’s logic hiding in normal English. (Unit 4—Arguments in Normal English)
• Detect when someone else is arguing badly with distraction, ambiguity, or form. (Unit 5—Informal Fallacies)
