Sisäloogisuus

Sisäloogisuus refers to the internal consistency of a system or argument. It is a philosophical and logical concept that assesses whether the various parts of a system, such as a set of beliefs, a theory, or a narrative, do not contradict each other. When a system exhibits sisäloogisuus, its components can coexist without creating logical paradoxes or inconsistencies.

The concept is crucial in evaluating the validity and soundness of many forms of reasoning and creation. For instance, in literature, a story with sisäloogisuus would adhere to its own established rules of reality, character motivations, and plot development, even if those rules differ from our everyday world. A scientific theory demonstrates sisäloogisuus if its postulates and derived conclusions are logically compatible. In legal reasoning, sisäloogisuus would imply that a judgment or set of laws does not contain conflicting directives.

Conversely, a lack of sisäloogisuus, known as internal inconsistency, undermines the credibility of the system. If a claim asserts "A" and also implies "not A," it contains a logical flaw. This does not necessarily mean the system is false in an external sense, but rather that its internal structure is problematic, making it difficult or impossible to accept as a coherent whole. Evaluating sisäloogisuus is a fundamental step in critical thinking and analysis.
