"The statement “You will recover from this illness” is either true or false. If it’s true, then it has been true for all eternity, and you’ll recover whether you summon a doctor or not.
If the statement is false, then it has always been false, and you will not recover even with a doctor’s aid.
So there is no point in calling a doctor."
