1. Deduction: This is the most common and fundamental process in logic. It involves deriving new conclusions from existing premises using a set of logical rules.
* Example:
* Premise 1: All humans are mortal.
* Premise 2: Socrates is a human.
* Conclusion (deduced): Therefore, Socrates is mortal.
2. Induction: This is a process of reasoning where you draw general conclusions from specific observations or examples.
* Example:
* Observation: The sun has risen every morning for as long as I can remember.
* Conclusion (induced): Therefore, the sun will rise tomorrow morning.
3. Abduction: This is a form of reasoning where you infer the most likely explanation for a given observation. It's often described as "inference to the best explanation."
* Example:
* Observation: The grass is wet.
* Possible explanations: It rained, someone watered the grass, a sprinkler was on.
* Abduction: The most likely explanation is that it rained.
4. Deductive-Nomological (D-N) Explanation: This is a specific model of scientific explanation that involves deducing a particular event from a general law and initial conditions.
* Example:
* Law: Objects in motion tend to stay in motion unless acted upon by an external force.
* Initial condition: A ball is rolling down a hill.
* Deduction: The ball will continue rolling down the hill unless something stops it.
