"Important principles may, and must, be inflexible"
About this Quote
The sentence is built like a moral gavel. "May, and must" moves from permission to obligation in four beats, a miniature argument that compresses political philosophy into cadence. It's also a warning aimed at the genteel centrism of his era: the belief that every conflict can be solved by splitting the difference. In the 1850s, that instinct was everywhere - in "popular sovereignty", in procedural bargains designed to keep the Union together by refusing to name slavery as a moral crisis. Lincoln understood the trap: if the principle at stake is human equality or the illegitimacy of bondage, compromise doesn't neutralize conflict; it launders it.
The subtext is strategic as much as ethical. Lincoln is not anti-politics; he's drawing a boundary that makes politics possible. If everything is up for barter, the strongest faction wins and calls it consensus. "Important principles" function here as constitutional bedrock: a shared floor beneath disagreement, not a ceiling that ends debate. He implies a hierarchy - tactics can bend, rhetoric can soften, timelines can adjust. The core cannot. In a nation allergic to absolutes, Lincoln argues that the only alternative to principled rigidity is organized moral drift.

Evidence: Such exclusive, and inflexible plan, would surely become a new entanglement. Important principles may, and must, be inflexible. (Collected Works of Abraham Lincoln, Vol. 8, p. 405). This line appears in Lincoln’s final public address, delivered from the White House on April 11, 1865, in remarks about Reconstruction (including Louisiana). A primary-source scholarly edition that prints it is Roy P. Basler et al. (eds.), Collected Works of Abraham Lincoln (New Brunswick, N.J.: Rutgers University Press, 1953), Volume 8, where the passage is on page 405. The University of Michigan Library Digital Collections provides the scanned/transcribed text of that volume at the URL given.
