illogic
Absence of sense
Illogic is the absence or violation of logic—reasoning that doesn't follow sound principles.
The word often appears as a noun naming this quality: the illogic of the argument, sheer illogic.
It emphasizes that something fails not just to persuade but to cohere rationally.
Less common than *illogical* but useful when you need a noun rather than an adjective.
