Truth-Apt
A statement is truth-apt if it’s the kind of thing that can be evaluated as true or false.
Why does this matter?
Only truth-apt statements can serve as premises or conclusions in an Argument.
| Truth-apt | Not truth-apt |
|---|---|
| “The lake is blue.” | “Close the door.” |
| “2 + 2 = 4.” | “Is it raining?” |
| “Vaccines cause autism.” (false, but still truth-apt) | “Wow!” |
The first norm in Norms of Assertion requires what you assert to be truth-apt.
