Critical thinking

You can learn to think in a new way.

It means asking many questions. You look at facts to find the truth. This helps you make good choices.

A long time ago, a man named Socrates taught this. He believed people should ask questions to learn. He wanted people to look at facts very closely.

This helps you see if an idea is right. It is a skill that anyone can learn. You can use it to solve problems. It helps you think better every day.

Critical thinking is a way to use facts. It helps you make good choices. You look at evidence to find the truth. This is not something we do naturally. We must learn to do it well.

Many people think this skill is very old. In Ancient Greece, a man named Socrates taught it. He believed people should ask many questions. He wanted people to look for real proof. He thought people should not just trust leaders. Instead, they should examine every idea.

There are different ways to use logic. One way is called deduction. This uses rules to find a certain answer. Another way is induction. This looks for a pattern in things. A third way is abduction. This uses what we know to make a likely guess.

Critical thinking helps you see many sides of an issue. It helps you notice errors in your own thoughts. You can train your mind to be more careful. This helps you understand the world much better.

Critical thinking is a way to use facts and evidence to make good choices. It is not just about solving a problem. Instead, it is about improving the way your own mind works.

When you think critically, you look at observations and arguments. You try to see the hidden assumptions behind an idea. You also look at different points of view to see if an idea is rational. This process helps you reach a fair judgment. It requires you to be skeptical and unbiased. This means you do not just believe things right away.

To practice this, you must develop certain habits of the mind. You have to be self-directed and self-disciplined. This means you take charge of your own learning. You must also be self-corrective. This helps you notice when you have made a mistake in your reasoning. It is important to overcome egocentrism, which is thinking only from your own view. You must also overcome sociocentrism, which is thinking only from your group's view. By doing this, you can communicate better and solve problems more effectively.

This way of thinking has a very long history. In the West, it began with the Greek philosopher Socrates. He lived from 470 to 399 BC. His student, Plato, wrote about him. Plato lived from 428 to 347 BC. In one story, Socrates debated whether it was right to escape from prison. He decided that escaping would violate the laws of Athens. Socrates taught that people should not just trust leaders or authority figures. He believed a good life comes from asking deep questions. He wanted people to have an "interrogative soul" that seeks out real evidence.

Over time, the way we talk about this has changed. The exact phrase "critical thinking" first appeared in a British journal in 1815. Later, a philosopher named John Dewey used the term "reflective thinking." In his book, *How We Think*, he helped shape the idea. In 1987, the U.S. National Council for Excellence in Critical Thinking gave a formal definition. They said it is a disciplined process of using information to guide belief and action. Today, many scholars say it also includes things like creativity and empathy. It is a skill that can be learned and trained.

Logic is a big part of how this works. There are three main types of logical reasoning used in this field. The first is deduction. This uses rules to find a certain answer, like knowing all humans have faces. The second is induction. This looks for patterns, such as seeing that adding even numbers always makes an even number. The third is abduction. This is making a likely guess based on what you see, like assuming sheep are white because they look white from your angle.

These tools help you tell the difference between true and false statements.

Critical thinking is a disciplined mental process used to analyze facts, evidence, and arguments. The primary goal is to reach sound conclusions or make informed choices. It involves more than just gathering information; it requires recognizing underlying assumptions. A thinker must provide justifications for ideas and then evaluate those justifications. This evaluation happens by comparing ideas against different perspectives to assess their rationality. By using skeptical and unbiased analysis, a person can form a fair judgment.

To practice critical thinking effectively, one must adopt specific habits of the mind. These include being self-directed, self-disciplined, and self-monitored. A successful thinker must also be self-corrective to fix errors in their own reasoning. This process is not a natural occurrence for most people. Instead, it must be induced through active ownership of the reasoning process. It also requires a commitment to overcoming egocentrism and sociocentrism. Egocentrism is focusing only on one's own view, while sociocentrism is focusing only on a group's view. Overcoming these allows for better communication and more effective problem solving.

The roots of Western critical reasoning are found in Ancient Greece. The philosopher Socrates, who lived from 470 to 399 BC, is a central figure. His student, Plato, lived from 428 to 347 BC, and he recorded Socrates' teachings. In one dialogue, Plato described Socrates debating the ethics of escaping from prison. Socrates concluded that escaping would violate the laws of Athens and his own guiding voice. This demonstrated his belief that authority figures do not always possess accurate knowledge. He argued that a good life requires an "interrogative soul." This means a person must seek evidence and examine the implications of every statement.

The terminology of the field has evolved significantly over many centuries. The word "critical" comes from the Greek word "kritikos," which means "critic" or "able to discern." While the roots are ancient, the specific phrase "critical thinking" first appeared in 1815. It was used in a British literary journal called The Critical Review. Later, the pragmatist philosopher John Dewey used the term "reflective thinking." In his book, *How We Think*, he helped define the concept based on an individual's knowledge base. By the late 19th and early 20th centuries, it became known as a general thinking skill.

Modern definitions have become increasingly detailed and specialized. In 1987, the U.S. National Council for Excellence in Critical Thinking provided a formal definition. They described it as an intellectually disciplined process of conceptualizing, applying, analyzing, and evaluating information. This information can come from observation, experience, reflection, reasoning, or communication. Contemporary scholars have even expanded these ideas further. They now include qualities like creativity, imagination, empathy, and even the concept of ambiguity. Some thinkers, like Richard W. Paul, argue that these competencies can be learned or trained through practice.

Logic plays a fundamental role in the structure of critical thinking. Logic is the study of argumentation and the correctness of those arguments. In the field of epistemology, critical thinking is viewed as logically correct thinking. This allows people to tell the difference between true and false statements. There are two main historical approaches to this. The "first wave" focused on a logocentric mode, which emphasizes being objective and abstract. This approach often assumes that good thinking is the same as logical thinking. The "second wave" of critical thinking has moved away from this exclusive focus on logic.

There are three distinct types of logical reasoning used to reach conclusions. The first is deduction, which draws a conclusion from the structure of premises. For example, if all humans have faces and X is human, then X has a face. The second is induction, which involves drawing conclusions from patterns. An example is noting that the sum of even integers is always even. The third type is abduction, which uses a heuristic to make a likely conclusion. If you see white sheep in a field, you might conclude sheep are white. This is a likely guess, but it is not as certain as a deductive statement.
