the impression of itself, defines and bounds that which is of itself<br />
indefinite. Hence in the human soul, there is a certain<br />
vestige of divine goodness, which moderates the inequality of<br />
its motions. This vestige is the rational power, by which we<br />
restrain the inordinate tendencies of desire, and the effervescence<br />
of anger, both which partake of the nature of inequality.<br />
This however will be evident, if we demonstrate that all the<br />
species of inequality originate from equality; so that obtaining<br />
as it were, the power of a mother and a root, she pours<br />
forth with primordial exuberance, all the species and orders of<br />
inequality. Let there be three equal terms, therefore, i.e. three<br />
unities, or three of the number 2, or of 3, or of 4, or of any<br />
other number. For that which takes place in one three terms,<br />
will happen in the rest. From the three rules therefore, that<br />
will be given, it will be seen, that in the first place multiples<br />
will be produced, first duple, then triple, then quadruple, and<br />
so on. Again, if the multiples are converted, from these superparticulars<br />
will arise. And from such as are duple indeed, the<br />
sesquialter; from such as are triple, the sesquitertian; from the<br />
quadruple, the sesquiquartan; and the rest after the same manner.<br />
But from the conversion of superparticulars, it is necessary,<br />
that superpartient ratios should be produced; so that the<br />
superbipartient will originate from the sesquialter; the supertripartient<br />
from the sesquitertian ; and the superquadripartient<br />
from the sesquiquartan. From the former superparticulars<br />
however, remaining in a direct position, and not being converted,<br />
multiple superparticulars will arise; but multiple superpartients<br />
will be produced, from thc position of the former<br />
superpartients remaining unchanged.<br />
The three rules however, are as follows: The first number<br />
must be made equal to the first; but the second, to the first<br />
and second; and the third, to the first, to twice the second,<br />
and the third. When this is effected therefore, in equal terms,
