men are blind in their own cause
1
used to imply that people may be unable to see the flaws or potential dangers in something they strongly believe in, due to their emotional investment in it
The proverb "men are blind in their own cause" originates from European cultures and reflects a long-standing observation about human nature. The saying highlights how personal involvement can cloud judgment, leading individuals to overlook their own mistakes or biases. It serves as a reminder that self-awareness is crucial, and one must make an effort to see things clearly, even when personal emotions or interests are at play.
- The man believed his actions were justified but could not see how foolish he appeared to others because men are blind in their own cause and cannot judge themselves objectively.
