[catalogued under 5. Theory of Logic / I. Semantics of Logic / 4. Satisfaction]

Full Idea

It has been found useful in defining semantical concepts to deal first with the concept of satisfaction; both because the definition of this concept presents relatively few difficulties, and because the other semantical concepts are easily reduced to it.

Gist of Idea

Satisfaction is the easiest semantical concept to define, and the others will reduce to it

A Reaction

See Idea 13339 for his explanation of satisfaction. We just say that a open sentence is 'acceptable' or 'assertible' (or even 'true') when particular values are assigned to the variables. Then sentence is then 'satisfied'.
