inkonsequent

Inkonsequent is a term used in logic and philosophy to describe an argument or claim that fails to follow logically from its premises, or that is out of step with the context in which it is presented. In English-language discourse it is closely related to the idea of a non sequitur—a conclusion that does not follow from the preceding statements. The term highlights a break in the inferential chain rather than a mere error in content.

Etymology and usage: The word appears in several European languages with meanings aligned to inconsistency or irrelevance in argument. In English, inkonsequent is uncommon; scholars usually translate it as non sequitur or inconsequent. It is used to critique argumentative moves that lack normative relevance or logical consequence, rather than to dispute factual claims.

Examples: An inkonsequent claim might be: "All philosophers love tea. Therefore, the meeting will start at noon." The premises do not establish the conclusion. Another example: "This policy reduces taxes. Therefore, crime will disappear." These illustrate failure of logical linkage between premise and conclusion.
