There is a popular Japanese saying “It’s up to you how you comment. But it’s me who take action after all.”
The line came from the answer of Katsu Kaishu (勝海舟-1823-1829), who was the leading figure of Tokugawa regime and contributed to peaceful turning-over of Ed Castle to Anti-Tokugawa revolutionary force in 1868 without shedding even a drop of blood, to the public comment by Fukuzawa Yukichi (福沢諭吉 1835-1901), enlightment thinker, journalist, and founder of Keio University criticizing Katsu’s defection from Tokugawa Shogunate to the dignitary of new government after Meiji revolution. Fukuzawa was also a vassal and middle class official of Tokuga regime.
To Fukuzawa’s cutting accusation of Katsu as a turncoat in the famous essay titled “痩せ我慢の説 - Importance of Perseverance and Royalty.” Katsu responded with 15 characters / two lines in a letter, saying “行蔵は我に存す。毀誉は他人の主張 - It’s me who take the action (and responsibility). It’s up to you (I don’t care) how you evaluate it and whatever you criticize me.”
When I get a down-vote or close vote, I mutter this word to myself. Are there equivalent wise sayings or historic remarks in English to the above?
