Logical Reasoning Methods - HTML
This resource explains the three reasoning methods that constitute logical thinking: deduction, induction, and abduction. Deduction derives specific conclusions from general principles, induction derives general laws from individual observations, and abduction infers the most plausible causes or hypotheses from observed results. These reasoning methods play crucial roles in problem-solving, decision-making, and innovation creation.

<tbody><tr><td>01</td><td>deduction</td><td>Deduction</td><td>A reasoning method that derives specific conclusions from general principles or laws.</td><td>High (Necessary)</td><td>General → Specific</td><td>Major premise: All humans are mortal. Minor premise: Socrates is human. Conclusion: Therefore, Socrates is mortal.</td></tr>
<tr><td>02</td><td>induction</td><td>Induction</td><td>A reasoning method that derives general laws or conclusions from multiple individual cases or observations.</td><td>Medium (Probable)</td><td>Specific → General</td><td>Observation: Fossils found at location A. Fossils found at location B. Fossils found at location C. Conclusion: There is a possibility that fossils are buried extensively in this area.</td></tr>
<tr><td>03</td><td>abduction</td><td>Abduction</td><td>A reasoning method that infers the most plausible causes or hypotheses to explain observed results or facts.</td><td>Low (Hypothetical)</td><td>Effect → Cause</td><td>Observation: Shell fossils found at location X, far from the sea. Condition: Shell fossils are usually formed in the sea. Hypothesis: Perhaps location X was at the bottom of the sea tens of thousands of years ago.</td></tr>
<tr><td>04</td><td>analogy</td><td>Analogy</td><td>A method that infers properties of one thing from knowledge of another based on their similarities.</td><td>Low to Medium</td><td>Transfer based on similarity</td><td>Birds fly (have wings) → Airplane design (structure with wings)</td></tr></tbody>
