THE SUPREME PRINCIPLES MUST BE SIMPLE AND NOT COMPOUND.

1. We have already seen[276] that the nature of the Good is simple and

primary, for nothing that is not primary could be simple. We have also

demonstrated that the nature of the Good contains nothing in itself,

but is something unitary, the very nature of the One; for in itself

the One is not some thing to which unity could be added, any more than

the Good in itself is some thing to which goodness could be added.

Consequently, as both the One and the Good are simplicity itself, when

we speak of the One and the Good, these two words express but one and

the same nature; they affirm nothing, and only represent it to us so

far as possible. This nature is called the First, because it is very

simple, and not composite; it is the absolute as self-sufficient,

because it is not composite; otherwise it would depend on the things

of which it was composed. Neither is it predicable of anything (as an

attribute in a subject) for all that is in another thing comes from

something else. If then this nature be not in anything else, nor is

derived from anything else, if it contain nothing composite, it must

not have anything above it.
