Critical Thinking: Using Logic and Reason

What is the best way to approach or deal with complicated claims? What is the best way to apply logic in order to construct sound arguments? What are logical fallacies in how can they wreck an argument? What other sorts of common errors do people make when creating arguments? What can science and philosophy do to help us in our arguments?
What is Critical Thinking? Establishing Emotional & Intellectual Distance Between You & Your Ideas
The term 'critical thinking' is used, in one form or another, throughout this site - but what does it mean? Some may get the impression that it simply involves finding fault with others and others' ideas, but that isn't really the case. As a general rule, critical thinking involves developing some emotional and intellectual distance between yourself and ideas - whether your own or others' - in order to better evaluate their truth, validity, and reasonableness.
Language, Meaning, and Communication: The Role of Language in Constructing Arguments
Although it might sound trivial or even irrelevant to bring up such basic matters as language, meaning, and communication, these are the most fundamental components of arguments - even more fundamental than propositions, inferences, and conclusions. We cannot make sense of an argument without being able make sense of the language, meaning, and purpose of what is being communicated in the first place.
Meaning: Denotation and Connotation - Definitions and Concepts in Critical Thinking
Understanding the difference between denotation and connotation is important to understanding definitions and how concepts are used. Unfortunately, that is complicated by the fact that these terms can be used in two different ways: grammatical and logical. Even worse, both uses are worth keeping in mind and both uses are relevant to project of logical, critical thinking.
Occam's Razor: Separating the Likely from the Unlikely
Quite often we'll hear someone say that assuming the existence of a god, of souls, of angels, of ESP, etc. violates 'Occam's Razor.' But what does the mean? What is 'Occam's Razor' and who is this 'Occam' person anyway?
Deductive and Inductive Arguments: What’s the Difference?
Arguments can be separated into two categories: deductive and inductive. A deductive argument is one in which it is impossible for the premises to be true but the conclusion false. An inductive argument is one in which the premises are supposed to support the conclusion in such a way that if the premises are true, it is improbable that the conclusion would be false.
Argument and Logic
What is an argument? What are logical fallacies? In order to debate well and think critically, we need the proper skills. Whether reading advertising, listening to politicians, buying a used car, or considering arguments for religion, we need to know how to carefully examine what is being said and consider the validity of the content or structure.
Flaws in Reasoning & Arguments
When a person's argument is flawed, usually those flaws can be traced back to identifiable fallacies. Not all flaws, however, can be technically labeled as fallacies. Some of these flaws might represent very specific errors in the reasoning process while others are better described as flaws in a person's attitude or how they approach the subject matter generally.
Logical Fallacies and Logical Arguments
Fallacies are defects in an argument - other than false premises - which cause an argument to be invalid, unsound or weak. By understanding what fallacies are, you can avoid making them and more easily detect them in the work of others.
