Value Rule 1
Editing Note. There are several versions of this Rule in the last couple of drafts I can find. I will try to figure out what's at issue here as I mark them up.
Variant 1
\(\text{Value Rule 1}\!\)
|
|
|
|
\(\text{If}\!\)
|
\(v, w ~\in~ \underline\mathbb{B}\)
|
|
\(\text{then}\!\)
|
\(^{\backprime\backprime} v = w \, ^{\prime\prime} ~\text{is a sentence about pairs of values}~ (v, w) \in \underline\mathbb{B}^2,\)
|
|
|
\(\downharpoonleft v = w \downharpoonright ~\text{is a proposition} ~:~ \underline\mathbb{B}^2 \to \underline\mathbb{B},\)
|
|
\(\text{and}\!\)
|
\(\text{the following are identical values in}~ \underline\mathbb{B}:\)
|
|
|
\(\text{V1a.}\!\)
|
\(\downharpoonleft v = w \downharpoonright (v, w)\)

Variant 2
\(\text{Value Rule 1}\!\)
|
|
|
|
\(\text{If}\!\)
|
\(v, w ~\in~ \underline\mathbb{B}\)
|

\(\text{V1c.}\!\)

\(\underline{((}~ v ~,~ w ~\underline{))}\)
|
|
Variant 3
A rule that allows one to turn equivalent sentences into identical propositions:
\((s ~\Leftrightarrow~ t) \quad \Leftrightarrow \quad (\downharpoonleft s \downharpoonright ~=~ \downharpoonleft t \downharpoonright)\)
|
Consider the following pair of expressions:
\(\downharpoonleft v ~=~ w \downharpoonright (v, w)\)
|
\(\downharpoonleft v(x) ~=~ w(x) \downharpoonright (x)\)
|
