The idea, stated plainly
A safe promise of principal and adequate return — everything else is speculation. That single sentence is the whole lesson in compressed form. The rest of the reading unfolds it — what it means when the terms are taken seriously, where it comes from, and what work it does inside Investing Foundations. Read the sentence, then read it again after the sections below; it should carry more weight the second time.

Common misreadings
The most frequent error is to treat Graham's definition as a slogan and skip the mechanics. The second most frequent is the opposite — treating the mechanics as the point, when the mechanics are only there to make the idea usable. Both errors collapse the same distinction, and both are correctable by returning to the one-line summary and asking what it actually claims.
