13633 | 'Satisfaction' is a function from models, assignments, and formulas to {true,false} [Shapiro] |
Full Idea: The 'satisfaction' relation may be thought of as a function from models, assignments, and formulas to the truth values {true,false}. | |
From: Stewart Shapiro (Foundations without Foundationalism [1991], 1.1) | |
A reaction: This at least makes clear that satisfaction is not the same as truth. Now you have to understand how Tarski can define truth in terms of satisfaction. |
