'No more this than that' makes clear our feelings: because of the equipollence of the opposed objects we end in equilibrium. (By 'equipollence' we mean equality in what appears plausible to us; by 'opposed' we mean in general conflicting; and by 'equilibrium' we mean assent to neither side.) Thus, although the phrase 'In no way more' exhibits the distinctive character of assent or denial, we do not use it in this way: we use it indifferently and in a loose sense, either for a question or for 'I do not know which of these things I should assent to and which not assent to'. Our intention is to make clear what is apparent to us, and as to what phrase we use to make this clear we are indifferent. Note too that when we utter the phrase 'In no way more' we are not affirming that it is itself certainly true and firm: here too we are only saying how things appear to us.
