Logos is an appeal to logic or reason. In poetry, it appears when a speaker tries to persuade through clear thinking, evidence, cause and effect, or a step-by-step argument rather than through emotion alone.
Poets may use logos in persuasive poems, satirical poems, and dramatic monologues where the speaker makes a case and expects the reader to follow the logic of the argument.
Example
You say the river is yours because you fenced the bank,
but water ignores a line in the dirt.
It follows the slope, the rain, the pull of stone,
and after every flood it leaves your claim behind.
