The idea
A cogent argument is an inductively strong argument whose premises are all true—induction's counterpart to soundness.
In practice
"Every observed emerald has been green, so the next will be": strong, true premises, cogent.
Where people slip
Cogency still guarantees nothing. A cogent conclusion is a well-earned bet, not a certainty—and that is the most induction ever offers.
