The term absurdnesses refers to things or situations that are illogical, nonsensical or ridiculous. In opposition to this word, we have terms such as rationality, sensibleness, and logic. Rationality denotes the state of being reasonable and sound minded. Sensibleness refers to good sense and practicality. Logic implies the existence of reasoned arguments and the consistent application of principles. These antonyms clarify a stance of clarity, balance, and resoluteness that contrasts the instability, disruption and uncertainty that absurdnesses carry. It is useful to consider the antonyms to broaden our analysis of a concept, in this case, the notion of illogicality, and its implications in different fields.
