Study Notes

Logical and Rational Arguments

A logical argument aims to prove a claim through reasoning.
A rational argument must exhibit a coherent flow from premises to conclusion.

Premises and Conclusions

Premises are propositions that support or justify a conclusion.
Conclusions are derived from premises and represent the outcome of an argument.

Soundness of Arguments

For an argument to be sound, premises must be accurate and logically linked to the conclusion.
An argument can only be deemed logical if both the flow and agreement between premises and conclusion are maintained.

Example of a Logical Argument

Premises:
- "Only citizens vote in Nigeria."
- "Tof votes in Nigeria."
Conclusion: "Therefore, Tof is a citizen of Nigeria."
The premises logically support the conclusion, validating the argument.

Example of a Flawed Argument

Premises:
- "Only citizens vote in Nigeria."
- "Tof breathes in Oxygen."
Conclusion: "Therefore, Tof is a citizen of Nigeria."
While both premises are true, the lack of logical connection between them results in a flawed argument.
