both are infinite; nor can it be ſaid, that of the infinite number,

an hundred thouſand is a greater part than two, though that be

fifty thouſand times greater than this; and if to the moving of

the Univerſe there be required a finite power, though very great

in compariſon of that which ſufficeth to move the Earth onely;
<

yet is there not implied therein a greater part of the infinite power,

nor is that part leſſe infinite which remaineth unimploy'd. </
