Quick Definition
The core of a circular fallacy is that it argues in a circle. Instead of providing independent evidence to support the conclusion, the argument simply restates the conclusion as a reason for itself. This makes the argument inherently invalid because it doesn't offer any new information or justification.
Begging the question is a common name for this fallacy, and it accurately describes the problem. The argument "begs" the listener to accept the conclusion without providing adequate support. It essentially assumes the truth of what it's trying to prove.
The fallacy can be difficult to spot because it often involves rewording the conclusion in a slightly different way. This can obscure the fact that the argument isn't actually providing any real support. Recognizing the rephrasing is key to identifying the fallacy.
Circular arguments are ineffective because they fail to persuade anyone who doesn't already accept the conclusion. Someone who doubts the conclusion will simply doubt the premise as well, rendering the argument useless. It only confirms existing beliefs.
The importance of identifying circular fallacies lies in promoting critical thinking and sound reasoning. Recognizing these fallacies helps us to avoid accepting arguments based on flawed logic and to construct more persuasive and valid arguments ourselves.
Historically, the concept of circular reasoning has been recognized since ancient times. Aristotle discussed similar fallacies in his work on logic, highlighting the importance of independent premises in argumentation.
Circular arguments can appear in various forms. Sometimes, the circularity is direct and obvious. Other times, it is more subtle and hidden within complex language or convoluted reasoning.
A classic example is: "God exists because the Bible says so, and the Bible is the word of God." This argument assumes the very thing it's trying to prove – the authority of the Bible as divine revelation.
