1. Anything existing after The First must necessarily arise from that First, whether immediately or as tracing back to it through intervenients; there must be an order of secondaries and tertiaries, in which any second is to be referred to The First, any third to the second.
Standing before all things, there must exist a Simplex, differing from all its sequel, self-gathered not inter-blended with the forms that rise from it, and yet able in some mode of its own to be present to those others: it must be authentically a unity, not merely something elaborated into unity and so in reality no more than unity’s counterfeit; it will debar all telling and knowing except that it may be described as transcending Being – for if there were nothing outside all alliance and compromise, nothing authentically one, there would be no Source. Untouched by multiplicity, it will be wholly self-sufficing, an absolute First, whereas any not-first demands its earlier, and any non-simplex needs the simplicities within itself as the very foundations of its composite existence.
There can be only one such being: if there were another, the two (as indiscernible) would resolve into one, for we are not dealing with two corporal entities.
Our One-First is not a body: a body is not simplex and, as a thing of process cannot be a First, the Source cannot be a thing of generation: only a principle outside of body, and utterly untouched by multiplicity, could be The First.
Any unity, then, later than The First must be no longer simplex; it can be no more than a unity in diversity.
Whence must such a sequent arise?
It must be an offspring of The First; for suppose it the product of chance, that First ceases to be the Principle of All.
But how does it arise from The First?
If The First is perfect, utterly perfect above all, and is the beginning of all power, it must be the most powerful of all that is, and all other powers must act in some partial imitation of it. Now other beings, coming to perfection, are observed to generate; they are unable to remain self-closed; they produce: and this is true not merely of beings endowed with will, but of growing things where there is no will; even lifeless objects impart something of themselves, as far as they may; fire warms, snow chills, drugs have their own outgoing efficacy; all things to the utmost of their power imitate the Source in some operation tending to eternity and to service.
How then could the most perfect remain self-set – the First Good, the Power towards all, how could it grudge or be powerless to give of itself, and how at that would it still be the Source?
If things other than itself are to exist, things dependent upon it for their reality, it must produce since there is no other source. And further this engendering principle must be the very highest in worth; and its immediate offspring, its secondary, must be the best of all that follows.
