Coherence Theory of Truth

The coherence theory of truth, on the other hand, suggests that a belief is true if it coheres with a system of beliefs. This means that a statement is true if it fits logically and consistently within a broader network of beliefs.

Philosophers like Alfred Tarski and Brand Blanshard have defended this theory. According to this view, truth is a matter of internal consistency within a system of beliefs. A belief is true if it is part of a coherent system of beliefs, even if it doesn’t directly correspond to external reality. For example, a mathematical theorem is considered true because it logically follows from a set of axioms and previously proven theorems.

Which Theory is Better?

Both theories have their strengths and weaknesses. The correspondence theory offers a simple and intuitive understanding of truth, but it can be difficult to determine the exact correspondence between beliefs and reality, especially in complex or abstract cases. The coherence theory, while appealing for its emphasis on logical consistency, can sometimes lead to circular reasoning, where a belief is justified by its coherence with other beliefs, without any external reference point.

Ultimately, the best way to understand truth may involve a combination of both theories. A belief can be considered true if it both coheres with our existing knowledge and corresponds to reality as we understand it. However, the exact nature of truth remains a complex philosophical question that continues to be debated.
