What is the meaning of logic and critical thinking

Critical thinking is essential for writing academic papers, particularly when writing an essay that requires you to demonstrate that one idea is better and more legitimate than other ideas. This is the basis and foundation of critical thinking. But how is logic defined? The Greek philosopher Aristotle developed the most common formula for logic, called a syllogism.

What is the meaning of logic and critical thinking

If p then q … where p and q can be any well-formed simple or compound proposition. This is an interesting semantic fact to ponder. With these rules you can analyze a compound sentence like the one above, and determine what the truth-value of the sentence is, for any combination of truth values of the component sentences.

This is what it means to say that this logical system is a truth-functional logic. The truth of the whole proposition is a function of the truth of the individual component propositions. In other words, once you fix the truth values of the parts, you automatically fix the truth value of the whole.

In propositional logic you also learn how to construct proofs using various rules of inference from p and q I can validly infer r and rules of replacement in a proof I can always replace p with q, since p and q are logically equivalent propositions.

Okay, my skeptical linguistics major is getting impatient. What does any of this tell us about natural language?


Not all of natural language behaves this way, but fragments of it certainly do. We can see, for example, that the following is a deductively valid inference: There is no oxygen in the room.

Therefore, the candle is not burning. For one thing, not all of natural language is truth-functional in the way that propositional logic requires. We can see this by comparing the following two sentences.

Clarity of thought is the basis for critical thinking, explained by Andrew Wittman, leading expert on mental toughness, critical thinking, and performance. The formal development of critical thinking is discussed, and guidance is provided to help faculty insure that critical thinking becomes an integral part of learning. Theory, research, teaching practice, and college programs pertinent to the development and role of critical thinking are presented in. Critical thinking is trendy these days. With million hits resulting from a Google search -- six times "Bloom's Taxonomy" -- its importance is undeniable. Worldwide, critical thinking (CT) is integrated into finger-painting lessons, units on Swiss immigrants, discussions of Cinderella, and the.

Because if it was, then the truth value of the whole statement would be uniquely determined by the truth value of the component statement. This is just one of many examples where the semantics of expressions in natural language is NOT properly modeled by the semantics of classical propositional logic.

And it reinforces my point, that formal languages like propositional logic can model aspects, or fragments, of the logical structure of natural language, but no single system can, or even attempts to, model ALL of natural language. Still, we can use artificial languages like propositional logic to investigate and learn about the logical properties of natural language, by comparing the semantics of these formal languages with the semantics of natural language.An important part of critical thinking is the use of logic.

This is not the place to say much more about logical thinking in general, and the basic principles of logic. Instead I here want to just focus on what are known as logical fallacies.

Critical Thinking is the process of using reasoning to discern what is true, and what is false, in the phrases and "sound bytes" we hear everyday. Part of it involves being familiar with logic and logical fallacies - those bits of false.

The essence of critical thinking is logic, and logical evaluation — by using reality checks and quality checks — is the essence of Design-Thinking Process and Scientific Method.

On the other end of the logic spectum, we see a variety of logical fallacies that .

Reflective thinking, on the other hand, is a part of the critical thinking process referring specifically to the processes of analyzing and making judgments about what has happened.

Dewey () suggests that reflective thinking is an active, persistent, and careful consideration of a belief or supposed form of knowledge, of the grounds that. Jul 12,  · Logical thinking is a useful set of tools ideally used within critical thinking.

Critical thinking is a more general set of mental tools we use to weigh evidence, evaluate the truthfulness and utility of statements, and generally accomplish our goals as both a society.
