koherenssiteoriat

Koherenssiteoriat, also known as coherence theories of truth, are a family of philosophical theories that define truth in terms of coherence. A proposition is considered true if and only if it coheres with a given system of propositions. This system can be one's beliefs, a set of established facts, or a body of knowledge. The core idea is that truth is a property of a proposition in relation to other propositions, rather than a direct correspondence with an external reality.

Different versions of coherence theories exist, varying in their interpretation of "coherence." Some emphasize logical consistency, meaning that a true proposition should not contradict other propositions within the system. Others include broader notions of coherence, such as explanatory power, comprehensiveness, and the absence of anomalies. For example, a belief coheres with another if it helps to explain or justify it.

Coherence theories face several challenges. One significant criticism is the problem of isolation, where a coherent system of propositions might be entirely false if it doesn't connect to the external world. Another issue is the possibility of multiple, equally coherent but mutually exclusive systems, making it difficult to determine which system, if any, holds the truth. Despite these challenges, coherence theories continue to be debated and refined in contemporary epistemology.
