There are many published incidents of this as an anonymous proverb since at least 1948, and as a statement of Eleanor Roosevelt since at least 1992, but without any citation of an original source. It is also often attributed to Admiral Hyman G. Rickover but, though Rickover quoted this, he did not claim to be the author of it; in "The World of the Uneducated" in The Saturday Evening Post (28 November 1959), he prefaces it with "As the unknown sage puts it..."

...Be less curious about people and more curious about ideas. (Marie Curie, undated (died 1934), as quoted in Living Adventures in Science by Henry and Dana Lee Thomas, 1972)
...Some professor of psychology who has been eavesdropping for years makes the statement that "The best minds discuss ideas; the second in ranking talk about things; while the third group, or the least in mentality, gossip about people"… (Hardware age, Volume 123, 1929)
...He now reports that, "the best minds discuss ideas; the second ranking talks about things; while the third and lowest mentality – starved for ideas – gossips about people." (Printers' Ink, Volume 139, Issue 2, 1927, p. 87)
...It has been said long ago that there were three classes of people in the world, and while they are subject to variation, for elemental consideration they are useful. The first is that large class of people who talk about people; the next class are those who talk about things; and the third class are those who discuss ideas... (H. J.

...[ Henry Thomas 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"… (Charles Stewart, "Haud immemor.

The Atheist Experience
Context: Your position is... one where there is a god who has an important message for mankind, and somehow he only reveals it to certain individuals who then write this down and thousands of years after this initial revelation, we have to rely on copies of copies of translations of copies by anonymous authors with no originals, and the textual testimony to a miracle, for example the loaves and fishes; there’s no amount of reports - anecdotal testimonial reports - that could be sufficient to justify that this event actually happened as reported. No amount. And anything that would qualify as a god would clearly understand this, and if it wanted to convey this information to people in a way that was believable, would not be relying on text to do so, and this for me is the nail in the coffin for Christianity. The god that Christians believe in is amazingly stupid if it wants to actually achieve its goal of spreading this information to humanity by relying on text; by relying on languages that die out; by relying on anecdotal testimony. That's not a pathway to truth! And anything that would qualify for a god should know this, which means either that God doesn’t exist or it doesn't care enough about those people who understand the nature of evidence to actually present it. Now which of those possibilities do you think is accurate?"... "Why would you believe anything on faith? Faith isn't a pathway to truth. Every religion has some sort of faith, people take things on, you know, - if faith is your pathway, you can't distinguish between Christianity, Hinduism, Judaism, any of these others. How is it that you use reason as a path to truth in every endeavor of your life, and then when it comes to the ‘ultimate truth’ - the most important truth - you're saying that faith is required. And how does that reflect on a god (who supposedly exists and wants you to have this information); what kind of god requires faith instead of evidence?... I have reasonable expectations based on evidence. I have trust that has been earned. I will grant trust tentatively. I don't have faith. Faith is the excuse people give for believing something when they don't have evidence.
