What a Logic Mind Map Covers
A logic mind map is a visual summary of formal reasoning. Its core is the proposition, a statement that is either true or false. Propositions combine through connectives such as and, or, not, if then and if and only if. Each connective has a truth table that defines when a compound statement holds, and these tables let you check arguments systematically.
- Propositions: atomic statements, symbols and truth values
- Connectives: negation, conjunction, disjunction, implication, biconditional
- Truth tables: systematic checks of validity and equivalence
- Inference rules: modus ponens, modus tollens and their relatives
- Fallacies: common invalid patterns that look persuasive
Use the map to review before an exam or to plan a proof step by step. CogniGuide can build a personalized logic map from your own notes so the structure matches your course.
Logic Mind Map Questions
Answers on what a logic map covers and how to make one from your own notes.
What is the difference between validity and soundness?
An argument is valid if its conclusion must follow when the premises are true. It is sound if it is valid and all its premises are actually true. A valid argument can still be unsound if a premise is false.
What does a truth table show?
A truth table lists every combination of truth values for the component propositions and shows the resulting truth value of a compound statement. It is a mechanical way to test whether a formula is a tautology, a contradiction or a contingency.
Which file types can I use to make a logic map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of your notes. You can also type a topic directly.
Can I turn my logic map into a quiz?
Yes. You can turn a map into a quiz to test yourself on connectives, truth tables and inference rules. CogniGuide also has a free plan with 5 creations a week.
