A person can be good at critical thinking, meaning that the person can have the appropriate dispositions and be adept at the cognitive processes, while still not being a good (in the moral sense) critical thinker. For example, a person can be adept at developing arguments and then, unethically, use this skill to mislead and exploit a gullible (易受骗的) person, perpetrate (作恶) a fraud, or deliberately confuse and confound (挫败), and frustrate a project.
The experts were faced with an interesting problem. Some, a minority, would prefer to think that critical thinking, by its very nature, is inconsistent with the kinds of unethical and deliberately counterproductive examples given. They find it hard to imagine a person who was good at critical thinking not also being good in the broader personal and social sense. In other words, if a person were "really" a "good critical thinker" in the procedural sense and if the person had all the appropriate dispositions, then the person simply would not do those kinds of exploitive and aggravating things.
The large majority, however, hold the opposite judgment. They are firm in the view that good critical thinking has nothing to do with any given set of ethical values or social mores. The majority of experts maintain that critical thinking conceived of as we have described it above, is, regrettably, not inconsistent with its unethical use. A tool, an approach to situations, these can go either way, ethically speaking, depending on the character, integrity, and principles of the persons who possess them. So, in the final analysis the majority of experts maintained that "it is an inappropriate use of the term to deny that someone is engaged in critical thinking on the grounds that one disapproves ethically of what the person is doing. What critical thinking means, why it is of value, and the ethics of its use are best regarded as three distinct concerns.
Richard Paul describes two beneficial dispositions that are encouraged (but not guaranteed) by critical thinking education:
"Fair-minded thinkers take into account the interests of everyone affected by the problem and proposed solutions. They are more committed to finding the best solution than to getting their way." And a critical thinker "has confidence that, in the long nm, one's own higher interests and those of human kind at large will be best served by giving the freest play to reason, despite the deep-seated obstacles in the native character of the human mind and in society as we know it."
Yes, reason is useful, it is noble and desirable, it should be highly valued and carefully developed. But we should keep things in perspective, regarding what reason can accomplish. Probably most of us will agree with Paul (about the value of critical thinking) but also with the majority of experts (that becoming skilled at critical thinking does not guarantee that this powerful tool will always be used for the benefit of others).
