noun
non sequitur; illogical conclusion
A conclusion or statement that does not logically follow from the previous argument or evidence. Used in logic, debate, and everyday conversation.

His argument is a non sequitur; it cannot be derived from the premises.
その発言は完全に不合理結論だ。
That remark is a complete non sequitur.
Refers to a leap in logic, often used similarly to 'non sequitur' but emphasizes the gap in reasoning rather than the conclusion itself.
Compound of 不合理 (illogical) and 結論 (conclusion). The exact historical derivation is uncertain; the term is a straightforward modern coinage.
