the.com/seeds of doubt

means A small, deliberately placed suggestion that makes someone start questioning something they previously trusted or believed.

from Built from the ancient farming metaphor of 'seed' as the start of something that grows unseen before it surfaces — a sense already old in religious and literary English, where faith, love, and sin were all said to be 'sown.' 'Doubt' comes from Latin 'dubitare,' to waver between two things, itself tied to 'duo,' two — the word carries indecision in its bones. The exact phrase 'seeds of doubt' is a natural pairing of these two old metaphors rather than a single coined phrase with a known inventor, and it hardened into cliché through centuries of use in rhetoric, religion, and persuasion, prized because it captures how doubt, like a seed, needs no further effort once planted — only time.
