The phrase “common sense” refers to sound practical judgment derived from experience and an understanding of ordinary situations.
Antonyms for “common sense” could include “foolishness” or “absurdity”.
“Foolishness” implies a lack of good judgment and making decisions that are unwise or ill-considered. For example, acting impulsively without thinking through the consequences is an act of foolishness, which is the opposite of using common sense. A person who spends all their money on unnecessary items without considering future needs is showing foolishness rather than common sense.
“Absurdity” refers to something that is extremely 不合理 or illogical. When actions or decisions are absurd, they go against what would be considered reasonable and practical. For instance, trying to build a house using only marshmallows would be an act of absurdity as it defies common sense regarding the stability and durability required for a building.
In conclusion, while common sense guides us to make practical and sensible choices, its antonyms like foolishness and absurdity represent actions and decisions that are unwise, illogical, and far from what is considered reasonable in everyday life.
