I didn't mean to imply that; I meant to explicitly say that.

... which appears to be explicitly incorrect.

  • If M is the set of all imessage users and S is "has received a blue dot spam message", then:

    gkoberger said:

    ∃m∈M ¬S(m)

    then mmlgr said pardon me, but:

    ∃m∈M S(m)

    and then you were like:

    ∃m∈M S(m)≡¬∃m∈M ¬S(m)

    but I've got to tell you:

    ∃m∈M S(m)≡¬∀m∈M ¬S(m)

    ∃m∈M ¬S(m)≡¬∀m∈M S(m)

    ∃m∈M S(m)≢∀m∈M S(m)

    • I would have been able to read this in school. Now I only know what it means from context.
