What is critical thinking? It doesn’t mean criticizing what people say. In this context, explains Sylvan Barnet and Hugo Bedau, the word critical “implies conscious, deliberate inquiry, and especially it implies adopting a skeptical state of mind” (3). Brooke Noel Moore and Richard Parker give the best short definition, “critical thinking is the careful application of reason in the determination of whether a claim is true” (3).
Why is critical thinking important? It is important because not everything you hear and read is true. And since none of us what to believe what is false, we must have some way to tell the difference between what is true and what is false. Nobody wants to be wrong. This is where critical thinking comes in. It gives you the skills to think more clearly.
Martin Cohen says that “Lesson One in critical thinking is that you need to always be aware that what you think on any issue may be wrong.” He goes on to say, “Lesson Two is the harder learnt: what you read others saying may be wrong too” (294). A skeptical state of mind is required in order to think critically about anything. We are too prone to overlook evidence that is contrary to what we already believe.
“The fundamental cause of the trouble,” writes Bertrand Russell, “is that in the modern world the stupid are cocksure while the intelligent are full of doubts” (Cohen 12). The sure sign of shallow thinking is the dogmatic attitude towards what they believe. As you grow older you realize the wisdom of the saying, “The wider the pool of knowledge, the greater the shores of ignorance.
But it is not just the claims that should be questioned, but the assumptions behind the claim. As Sylvan Barnet and Hugo Bedau writes, “Critical thinking means questioning not only the assumptions of others, but also questioning your own assumptions” (5). Assumptions are the things we take for granted. Wrong assumptions lead to wrong conclusions.
Claims and Beliefs
A claim, sometimes called a truth claim or proposition, is “a statement that is either true or false” (Moore and Parker 500). Not all statements are claims, but many statements are. In fact, we hear claims every day of our lives. The problem is that we don’t question these claims and ask if they are really true. A claim is true if it corresponds to reality, it is false if it does not. When what you think matches the way things really are, you have a true claim.
The best definition of truth is that it is the correspondence of thought and reality. Every other attempted definition has to assume this one. In other words, every other definition has to assume that their definition corresponds to the reality of what truth is.
Now the truth of a claim can never be absolute or certain. The truth of a claim cannot be absolute, because we do not know everything, and what we don’t know might show that the claim is false. This also means that we can never be absolutely certain of any claim. This is true for every aspect of human endeavor, from science to philosophy.
Furthermore, a claim can never be completely comprehensive. In other words, a claim is made of words, and words are not reality – they are symbols created to represent reality. As such, words cannot contain the depth and scope of reality itself. This is why Zen Buddhism warns us about mistaking the symbol for the reality. Just because you know the definition of humility doesn’t mean you have humility.
Beliefs are claims that we have accepted as true. Critical thinkers should be careful about what they accept as true. They should have good reasons for the things they believe. But many times we don’t have good reasons. Often times we just accept the beliefs of family, friends, and the media. We should learn not to automatically believe everything we hear. We should test it out, think it through, weigh the evidence, discern the assumptions, and come to a reasoned decision.
Faith and belief are different, and you should be aware of this difference. Belief is merely the accepting of a claim as true. It says nothing about the grounds for that belief. Some beliefs are justified, which means there are good reasons for accepting them. Other beliefs are unjustified, they are reached not by solid reasoning but bias, prejudice, or emotional considerations. The point is that the word belief says nothing about the grounds of accepting a claim.
Faith, on the other hand, does indicate the grounds of belief, or the lack thereof. Faith is accepting a claim as true without evidence, without good rational reasons. Faith and trust should not be confused, trust is confident reliance on a person or thing, but says nothing about whether this trust is warranted. In this sense, trust is like belief, it does not indicate whether the grounds for the trust or belief is good, bad, or nonexistent.
Claims are statements that are true or false. Once a claim is accepted as true it becomes a belief, and beliefs are very important. As Joyce and River Higginbotham point out, “What you believe about yourself and your world determines to a large extent the kinds of experiences you will have and how you will interpret them” (45). Your experiences in life are limited by your beliefs, and then they are interpreted by your beliefs.
If you take a hike on a mountain and are suddenly in rapt awe, your experience will be filtered through your beliefs. This network of beliefs is called a paradigm, it is the mental map you have created of the world. It is the world as you interpret it, your worldview. The rapt awe will be interpreted by a Pagan as union with Mother Nature and a Christian as God. All our experience are filtered and altered by what we believe. Beliefs shape your view of reality, and as such, they shape your life.
The problem is that paradigms allow us to make sense of the world, but they also blind us. We can’t see any other perspective but our perspective. Everything makes so much sense to us, we are just so certain that reality is how we envision it. We are caught in the paradigm prison, a prison for the mind.
Paradigms are not optional, we need them to think at all. They are our effort at trying to fit the pieces of the puzzle of reality together. Unfortunately, many us inherited our paradigm from our family and society, and few actually question the paradigm that they inherited. This is why, generally speaking, Muslims come from Muslim countries, Christians come from Christian countries, Hindus come from Hindu countries, and so on. Being born into a Muslim country is not a good reason to be a Muslim.
Critical thinkers know the dangers of being stuck in a particular viewpoint, and that is why they try to expand their vision, look at things from a different perspective. They know that a claim that can’t be tested shouldn’t be trusted. Sometimes you may find that the opponent’s viewpoint is actually closer to the truth. They you will have to decide whether you follow the truth or whether you just don’t want to be wrong. You might also discover that we believe many things for other than rational reasons.
Possibility and Probability
Since the truth can never be known with absolute certainty, we need to accept the fact that we will never know for sure that we are right. That should bring a sense of humility and perspective into every conversation. But for some people, that will cause distress and unease. For if we don’t know anything for sure, what about questions of God, death, hell, and the afterlife?
This is when it is helpful to remember the difference between the possible and the probable. Many things are possible, but few things are probable. The key is to believe the probable, and be open but unbelieving of the possible. The possible could possibly be true, but we have no good reason to believe it is. The probable is that which we have good reason to believe is true.
There are only three options we can take when dealing with a claim. We can accept the claim, reject the claim, or suspend judgment concerning the claim. Accepting the claim means believing it, rejecting the claim means disbelieving it, and suspending judgment means that we are still in doubt about the claims status. The question is on what basis should we make the decision?
Evidence is the basis for accepting or rejecting a claim, and a lack of evidence either way is the basis for suspending judgment. By evidence I mean objective and verifiable facts, observations, or inferences. The ultimate authority for the critical thinker is evidence. The scientific method is the best self-correcting means to evidence that we have developed. The further we get from science and into more subjective things, and the more careful we need to be in our thinking.
In weighing the evidence, you are trying to reason to the most probable claim that offers the best explanation of the evidence. You want to make sure the claim is logical and consistent, based on objective physical observations, that it works in real life, and that it answers best all the questions raised by the issue.
The Burden of Proof
There is a teapot buried 12 feet deep somewhere on Pluto. Do you believe me? Why not? You can’t prove that the claim is false. I mean, it could possibly be that NASA sent a probe to bury a teapot on Pluto. It could be true, I mean it is possible, no matter how very unlikely.
First, this demonstrates the difference between the possible and the probable. A teapot on Pluto is not probable and therefore should not be believed. But a second point is revealed by the line, “You can’t prove that the claim is false.” Possible claims and mere assertions are the same thing. And this is why the understanding the burden of proof is so important.
The rule of the burden or proof says that a person who makes a positive claim has the burden to prove it. In other words, if you affirm that something is the case, it is your responsibility to give good reasons for accepting your claim. This also means that the person denying a claim has no obligation to prove a negative. In the case of the teapot, the burden of proof says you have no obligation to prove that there is no teapot on Pluto. Rather, it is my job to first give you evidence of my claim.
Once an affirmative claim is made and evidence is offered, it is only then that the burden of proof switches to the person denying the claim.

5 thoughts on “Critical Thinking”
“Reason is in fact the path to faith, and faith takes over when reason can do no more.” -Thomas Merton.
Critical thinker, yes. Faithless, no. – Patty Kay
I enjoyed your article! I think that most who claim faith have no reason. And I think many do.
Does it really matter? Just because some do not need proof for everything, doesn’t mean they can’t be critical thinkers.
Hi Patty, although I enjoy some of what Thomas Merton has written, I must disagree with him here. Rational belief is accepting a claim for good reasons, logical and empirical reasons. Faith is accepting a claim without evidence. Clear logical thinking that follows the evidence is not “the path to faith.” It is the path to truth. Truth is the correspondence between thought and reality. How are you going to know that your thought matches reality? By following the evidence.
Does it really matter? It depends on whether or not truth is important to the person. The path to truth is evidence, not faith. Evidence will lead you to the most probable answer. Faith is not a path to truth. That is why there are so many faiths and none of them agree. Being a critical thinker does, in fact, mean that you follow the evidence to the best possible claim, at least on all important issues.
W. K. Clifford is famous for saying, “It is wrong always, everywhere, and for anyone, to believe anything on insufficient evidence.” Thomas Henry Huxley put it this way, “it is wrong for a man to say he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty.” A more colloquial way of saying the same thing, in the words of English historian G.M. Young, “a man has no more right to an opinion for which he cannot account than to a pint of beer for which he cannot pay.” My advice is, “Don’t believe beyond the available evidence.”
I appreciated your response.
Concerning Merton, he’s difficult to read … long sentences and even longer paragraphs. I’m not looking for a debate, really … and I don’t think you’re making it one.
I enjoyed your essay, I just think about old Merton when I read something along your lines.
Truly, I’ve read more than Merton about faith and no matter how hard I try, I just can’t say I don’t have it. Faith in Something I have no clear image of, except for all that is.
I enjoy reading other points of view. The only thing I really know is that I don’t know.
So more power to you. You are a good writer!
Hopefully your friend, and definitely an admirer,
Hi Patty, thank you for your response. I never found Merton hard to understand, I just disagree with his beliefs. When I was a Christian I was a big fan. He was a gentle and sincere teacher and was open-minded for a Roman Catholic.
I understand that feeling of “Something” greater. It is real, but interpretations differ. Some call it God, others the Tao, and yet others, like myself, I call it Nature. Nobody has all the answers, certainly not me.
My path is to follow the evidence to the best possible explanation. At the same time we have to realize the limits of what we know. That humility will keep us open to reality as it unfolds and help us live in harmony with one another, despite our differences of opinion.
Count me as your friend.
I must say, I am enjoying this exchange. You make me think. And what may seem laughable, I’m not thinking I should change my thinking, but thinking how I can explain it without the need to defend it.
I don’t know how to convey my agreement with you without explaining the differences in our fundamental understanding. Perhaps the main issue is vernacular. “You say tomato, I say tomaHto.”
What you call Nature, I call God. It really is that simple. At some point, all the evidence, all the verifiable comes to an Uncreate. If it all began with the Big Bang, or whatever you choose to call the emergence of Being outside eternity, okay. Then, to me, God is the Universe. Something had to be to cause, or become, that. If it is Nature, okay. I still call it God.
If our Universe is a bubble, or a wave amongst countless other waves or bubbles, then there is an Uncreate that existed to usher in all the Universes that are, have been, or will be. Or, I can imagine that eternity is a human-made construct and nothing I see or feel even exists. I am an avatar.
Regardless, I am. To me, that’s all the evidence I need. Human or avatar, here I am. And I respect and honor however I came to be, mostly because I like Being, or imagining I’m being.
Merton isn’t hard to understand. He’s very wrapped up in a patriarchal frame of mind. But that doesn’t mean that everything he says is wrong. He Is hard to read, for me, because I’m in search of meaning out of what is, literarily, rambling. I prefer pithy little sayings.
I am perfectly willing to accept that my thinking is full of beans. But I don’t think my beans add up to a hill in the giant scheme of things. It is how I can best understand the “how.” I’m still trying to figure the “why,” but I’m comfortable never being sure. In terms of my existence, I know that it is finite. A bitter pill, perhaps, but I’ve swallowed it.
If I’ve had past human lives, I’ve always been some version of a Kitchen Wench who has been raped and pillaged by patriarchy and maybe this time around I’m too aware of that fact to want no more. Maybe I’ll die and that’s it. Or maybe, just maybe, I get my fondest wish and my energy will merge with whatever flow there is. Whatever, I know my physical remains will be cremated after all the usable parts have been donated. Any ashes will fertilize a tree.
What concerns me is Now. “Now is the time, now is the place, this very day is salvation.” ~ A song I don’t remember much about, except that line. ~ And what is salvation to me? That my finite existence doesn’t impede other existence and that I work to ensure existence continues in whatever form Nature or God deems it to be.
A friend of mine posted a Facebook link to an article about a bug that eats plastic. A leap of imagination from there, I can envision “Nature’s Revenge.” LoL I don’t think there will ever be enough of the bugs to eliminate all the waste humans have produced, but maybe it’s a hint. The Earth is in self-preservation mode. Humans think it’s okay to frack and to demonstrate it’s not, the Earth quakes. We trash up the place and Earth responds. If you want to call it Nature, then Nature is producing Super Bugs that are not responsive to human-made treatments. In a war, I’m certain that Nature would win.
A tangent, sorry!
So, let me conclude with a tip I use to cope with the horrors of this existence. I got it from a daily meditation I receive from the “Center for Action and Contemplation” ….
