ABSTRACT
IN the foregoing Lecture we have spoke sufficiently concerning the Nature of Space and certain Mathematical Hypotheses which are drawn from thence. The next Affection of Magnitude, which offers its self, is Congruity; the Supposition of which is as it were the chief Pillar and principal Bulwark of all the Mathematics. For from hence, in my Opinion, is taken the formal Reason of Equality, which is all in all in the Mathematics; and, as (k) Proclus says, the most original Affection in Quantity: at least it is in fact the most principal Criterion, and affords the leading Argument of the same; as it will be perhaps worth while to shew.
