Goatism Proved by Logic!

Introduction to Propositional Logic

In Propositional Logic every statement is either true or false. There is no third way. For example, the proposition "It is raining outside" is either true or not true. Furthermore, if a statement is false then it's opposite is true. So, if "It is raining outside" is a false statement, then it's opposite "It is not raining outside" must be true.

The Logical Proof

1. The proposition "Everything is a Goat" is either true or not true.
2. If it is false, then it's opposite must be true.
3. The opposite of "everything" is "nothing", which give us the proposition "Nothing is a Goat".*
4. Now, this statement is clearly false, for goats certainly exist - we have all seen them. This means that it's opposite must be true.
5. Therefore, "Everything is a Goat" must be a true statement.

*Sophists may argue that we should negate the object rather than the subject of this sentence; but this simply gives us the statement "Everything is not a Goat" which is logically identical to "Nothing is a Goat".
