Q. Need the definition of Arab proverb: The wise man speaks of ideas, the middling man of actions, the fool of persons
I could not find this attributed as an Arab proverb. Several sources gave the author as "unknown." In several other sources it is attributed to Eleanor Roosevelt (Oct 11, 1884-Nov 7, 1962), but without definite citation, and Admiral Hyman G. Rickover, U.S.Navy (Jan 27, 1900-July 8, 1986), who acknowledged quoting it, but did not claim to be the author of the statement. However, several sources claim Henry Thomas Buckle, (Nov 24, 1821-May 29, 1862). He was an English historian and author of A History of Civilization.
Mr Buckle is quoted in Conversation: What to Say and How to Say it, by Mary Greer Conklin, New York, NY; Funk & Wagnalls Company, 1912, page 179, and Charles Stewart wrote the following in Haud immemor. Reminescences of legal and social life in Edinburgh and London. 1850-1900, 1901, p 33.
...[Buckle's] thoughts and conversations were always on a high level, and I recollect a saying of his which not only greatly impressed me at the time, but which I have ever since cherished as a test of the mental calibre of friends and acquaintances. Buckle said, in his dogmatic way: "Men and women range themselves into three classes or orders of intelligence; you can tell the lowest class by their habit of always talking about persons, the next by the fact that their habit is always to converse about things; the highest by their preference for the discussion of ideas."
