I ask, whether the complex idea in Adam's mind, which he called KINNEAH, were adequate or not?
And it is plain it was; for it being a combination of simple ideas, which he, without any regard to any archetype, without respect to anything as a pattern, voluntarily put together, abstracted, and gave the name KINNEAH to, to express in short to others, by that one sound, all the simple ideas contained and united in that complex one; it must necessarily follow that it was an adequate idea.

His own choice having made that combination, it had all in it he intended it should, and so could not but be perfect, could not but be adequate; it being referred to no other archetype which it was supposed to represent.

These words, KINNEAH and NIOUPH, by degrees grew into common use, and then the case was somewhat altered.

Adam's children had the same faculties, and thereby the same power that he had, to make what complex ideas of mixed modes they pleased in their own minds; to abstract them, and make what sounds they pleased the signs of them: but the use of names being to make our ideas within us known to others, that cannot be done, but when the same sign stands for the same idea in two who would communicate their thoughts and discourse together.

Those, therefore, of Adam's children, that found these two words, KINNEAH and NIOUPH, in familiar use, could not take them for insignificant sounds, but must needs conclude they stood for something; for certain ideas, abstract ideas, they being general names; which abstract ideas were the essences of the species distinguished by those names.
