Critical thinking is independent thinking, thinking for oneself.
Critical thinkers use critical skills and insights to reveal and reject beliefs that are irrational.
Nor are they unduly influenced by the language of another. If they find that a set of categories or distinctions is more appropriate than that used by another, they will use it. Recognizing that categories serve human purposes, they use those categories which best serve their purpose at the time. They are not limited by accepted ways of doing things. They evaluate both goals and how to achieve them.
