That does not assign Sally to everything red. The red hair is the subject. The sentence simply states that Sally has red hair somewhere on her body, has Red hair on her person, or owns red hair.
Please learn grammar!
Sally has red hair. or Sally's hair is red..
"red hair" or "red" is not the subject. It is the predicate.
The understood quantifier of "Sally" is "All" (All Sally...).
Now in strict logical form, your statement is this (brackets separate terms):
All [Sally] is [that which has red hair]. or All [Sally's hair] is [that which is red].
Because the quantifier of [Sally] or [Sally's hair] is All, it is distributed. The predicate ([red hair] or [that which is red]) is always undistributed in universal affirmative statements, such as the two Sally statements.
If JoS was saying that those statements are equivilent to 92=92, he would be assigning [Sally] or [Sally's hair] to all [red things]. We know that some [red things] are not [Sally] or [Sally's hair], so JoS is wrong if he is saying it is equivilent to 92=92.
Kalraken, I'm a couple weeks away from completing my second year of logic. I have taken grammar for more than 8 years. You better be dang sure when you're saying I'm wrong.
Back to the point of this topic..
JoS said "Everything I say is a lie." (or something very close to that).
I will expand on this:
"Everything I say is a lie."
If I lie about everything, then that statement is true, so I am telling the truth. But if that statement is true, then some things I say are not lies, including "Everything I say is a lie". That means that "Everything I say is a lie" must false. But if some things I say are not lies, my satement that "Everything I say is a lie" must also be false. This will go in a contradictory circle, much like "What came first - the chicken or the egg?" because you need one for the other, for example, a chicken can only come from an egg, but the egg is made by the chicken.
So there must be such a thing as truth, or else nothing could exist.
And if nothing exists, there is nothing that can be true because there is nothing to be true.
Anything that can be empirically proven is either true or false, everything else is opinion.
Baseball is better than Football
Cheese tastes better with Wine
Apple makes the best products known to man
all subjective and opinionated, therefore not true.
