Hugo Steinhaus was also an author of aphorisms, which he published in the daily "Slowo Polskie" under a pseudonym Sestertius.  Most were just goofy definitions of everyday terms. The following example seems to do OK in translation from Polish: "An opinion that all high-rank officers are stupid: a generalization".  The book edition ("Slownik Racjonalny") appeared in 1980 (after his death) under his real name.
