Study Notes
Deductive Reasoning
- The main characteristic of deductive reasoning is that it involves deriving a conclusion that follows necessarily and with absolute certainty from one or more premises.
- The philosopher attributed to the development of the syllogism is Aristotle.
- The core concept of deductive reasoning is that the conclusion follows with absolute certainty from the premises.
Greek Philosophers and Deductive Reasoning
- Greek philosophers associated with the development of deductive reasoning include Aristotle, Plato, and the Stoics.
Conditions for Deductive Validity
- For an inference to be deductively valid, it is required that the conclusion follows necessarily and with absolute certainty from the premises.
False Premises and Deductive Reasoning
- A false premise can possibly lead to a false conclusion in deductive reasoning.
Inductive Reasoning
- The process of deriving a reliable generalization from observations is known as inductive reasoning.
- In inductive reasoning, a generalization is made based on specific instances or observations.
- In deductive reasoning, anyone who accepts the premises must also accept the conclusion.
Example of Deduction
- An example of deduction is: All humans are mortal, Socrates is human, therefore Socrates is mortal.
Characteristics of Inductive Reasoning
- Inductive reasoning involves making a generalization based on specific instances or observations.
- It usually involves a rule being established based on a series of repeated experiences.
- An example of strong induction is: The sun has risen every morning, therefore it will rise again tomorrow.
Limits of Inductive Logic
- In inductive logic, the truth of the conclusion is not guaranteed, even if the premises are true.
