What knowest thou, that we know not? What understandest thou, which is not in us?
What do you know that we know not? What do you understand that is not equally clear to us?
What do you know that we don’t know; what do you understand that isn’t among us?
What do you know, about which we are ignorant? What do you understand that we do not know?
What knowest thou that we are ignorant of? What dost thou understand that we know not?
