I. Pop-quiz paradox...

(next)

 

 

 

 

 

 

 

 

 

 

 

We'll see that the answer to the pop-quiz symbolization question involves saying that ALL remaining class days are IDENTICAL to either a, b, c, or d.

 

II. So: identity! We'll add one specific predicate to PL in order to make PLI, predicate logic with identity.

  1. Let's begin by saying that "George is identical to the president but distinct from the winner of the MI vote"


















  2. How would we say that "George and someone else lives in the White House"?




























  3. Now, symbolize: "At least two people live in the White House".














  4. Next: "All males except George live outside the White House."



































  5. Finally: "The president lives in the White House"
