I Do Not Think Much Of

This quote is widely attributed to Lincoln in secondary compilations and quotation anthologies, but it lacks a verified primary source — no specific speech, letter, or documented remark has been identified in the Collected Works of Abraham Lincoln. The attribution may stem from a related passage where Lincoln, writing about Stephen Douglas, used the phrase "a man may rightfully be wiser today than he was yesterday," demonstrating his familiarity with the idea. Without a confirmed primary source, the attribution should be treated as unverified.
