koherensteorin

Koherensteorin, or coherence theory, is a philosophical concept that addresses the nature of truth and justification in a belief system. It posits that a belief is justified if it coheres with other beliefs held by an individual. Coherence, in this context, refers to a relationship of mutual support or consistency among a set of beliefs. A system of beliefs is considered coherent if its components fit together logically and do not contradict each other. This theory stands in contrast to foundationalist theories, which argue that some beliefs are self-evident and serve as the foundation for all other justified beliefs.

There are different versions of coherence theories. Some focus on the logical consistency of beliefs, while others emphasize the explanatory power or predictive success of the belief system as a whole. A core idea is that the justification for a single belief is not isolated but arises from its place within a larger web of interconnected beliefs. If a new belief is introduced that is inconsistent with many existing beliefs, it is less likely to be accepted or considered justified. Conversely, a belief that aligns well with a robust and consistent set of existing beliefs is more likely to be deemed coherent and thus justified. The challenge for coherence theories lies in defining the precise nature of coherence and addressing potential issues like the possibility of multiple equally coherent but competing belief systems.
