Critical Thinking
email me

"It is the mark of an educated mind to be able to entertain a thought without accepting it."
- Aristotle

"Defending one’s beliefs despite contrary evidence is the highest mark of stupidity."
Critical thinking is the process of using evaluated reasoning to reach logical conclusions about
arguments.

Experts agree that critical thinking consists of six key areas. My definitions follow:

1. Interpretation: Correctly extracting the intended and essential meaning from information.
2. Analysis: To assess the parts and relationships of communication.
3. Evaluation: To use intellectual standards to judge the truth, credibility, or logical strength of a
statement.
4. Inference: To draw reasonable meaning, conclusions, or consequences from information,
knowledge, or evidence
5. Explanation: To “attempt to show why or how something happens” (William Hughes).
6. Self-regulation: To consistently apply rules of intellectual expertise to one's own arguments.
