seemingness (uncountable)

semblance; fair appearance; plausibility

So that, certainly, if it were not for the authority of Aristotle and of his learned followers that presses us on the one side and for the seemingness of those reason we have already mentioned which persuade us on the other side, our very eyes would carry us by stream into this consent, that light is no other thing but the nature and substance of fire, spread far and wide and freed from the mixture of all other gross bodies.
