Einstein thought highly of Vladimir Lenin, saying: "I honor Lenin as a man who completely sacrificed himself and devoted all his energy to the realization of social justice. I do not consider his methods practical, but one thing is certain: men of his type are the guardians and restorers of humanity."

Written between October 1922 and March 1923, the diaries of Einstein released in 2018 contains what has been called racist remarks. He notes how the “Chinese don’t sit on benches while eating but squat like Europeans do when they relieve themselves out in the leafy woods. All this occurs quietly and demurely. Even the children are spiritless and look obtuse.” After earlier writing of the “abundance of offspring” and the “fecundity” of the Chinese, he goes on to say: “It would be a pity if these Chinese supplant all other races. For the likes of us the mere thought is unspeakably dreary.”

Einstein’s perceptions of the Japanese he meets are, in contrast, more positive: “Japanese unostentatious, decent, altogether very appealing,” he writes. “Pure souls as nowhere else among people. One has to love and admire this country.”[41][42]
