# logic

Here are some of the most common logic symbols used in philosophical logic:

- $\neg$ : negation (not)
- $\land$ : conjunction (and)
- $\lor$ : disjunction (or)
- $\rightarrow$ : conditional (if...then)
- $\leftrightarrow$ : biconditional (if and only if)
- $\forall$ : universal quantifier (for all)
- $\exists$ : existential quantifier (there exists)
- $\therefore$ : therefore (conclusion)
- $\because$ : because (premise)

These symbols are used to represent logical operations and relationships between propositions or statements.

## cormac mccarthy propositional logic

It is possible to express the quote "the extinction of all reality is a concept no resignation can encompass" in propositional logic using symbols and operators. Here's one possible representation:

Let P represent "the extinction of all reality is a concept."
Let Q represent "no resignation can encompass P."

The statement can then be expressed as:

P ∧ Q

This can be read as "The extinction of all reality is a concept and no resignation can encompass it."

Sure! Here's the Cormac McCarthy quote in MathJax:

$$\neg(\forall x)Rx \rightarrow (\exists x)\neg Rx$$

This can be read as "The extinction of all reality is a concept that cannot be encompassed by any resignation."
