Fukuzawa gives Rampo a pair of glasses, claiming that wearing them would activate his ability to instantly determine the truth of any situation, and taking them off would give him the ability to tolerate the stupidity of the ordinary person.
you will no longer be bothered 
by the foolishness of others.
.لن تنزعج بعد من حماقة الآخرين
la stupidità degli altri non ti darà più alcun fastidio.
não será mais incomodado
pela estupidez dos outros.
людская глупость
не будет тебя беспокоить.
