It is easy enough to google the complete unabridged description. These proofs have been discussed for centuries. I attended jesuit h.s. and college and had exposure to Thomas’ proofs in fairly concentrated form, but, at the end of the day, it always seemed to me that these proofs boil down to one simple argument which I don’t find all that persuasive. The argument is that there can’t be an infinite regression. Somewhere the buck stops and where it stops is a person called god.
Will:
Too bad you did not attend a good Catholic college after h.s. God prevented that, for some reason unexplainable to us.
Altogether, in my view,this simply reduces to the proposition that there must be an “ultimate principle” accounting for “esse”. This actually isn’t that profound of an insight, in my judgment. Perhaps as we learn more about the quantum it may be so that there is one single defining principle which accounts for what there is. Who can say really?
As you will no doubt recall, there was a simple example that used to be given which, while not extending infinitely back, permitted us the luxury of understanding what St. Thomas meant. It was the story of the boy who was pushing a stone along a walk-way with a stick. Obviously, the stone is moved by the stick and the stick is moved by the boy’s hand, while the boy’s hand is moved by the boy. Simple enough. But, is that all there is? Is that where it stops: at the
boy?
From there it gets more complicated and more difficult to put into a parsimonious, yet fully explanatory description. From the boy’s hand we go to the boy’s forearm and attendant muscles, from there to the boy’s upper arm and attendant muscles, from there to the boy’s should and attendant muscles. from there to the boy’s torso and attendant muscles, from there to the boy’s hips and attendant muscles, from there to the boy’s legs and attendant muscles, from there to his feet and attendant muscles, then to the attendant nerves going back to the brain, then to the gastric system which provides the energy required by the nerves and muscles to operate, then from the brain to the prior intentions of the boy to take the stick and move the stone, from there to the tissues, atoms and quantum particles set into motion, and this could go on and on. Intentions, desires, birth, care, formation, food matter for energy, hydrogen and oxygen for transport, oxygen, carbon dioxide and nitrogen, for replacement of and expulsion of problematic gases, etc., etc. Amalgamations of atoms into elements. Amalgamations of quantum particles into atoms. (As you can no doubt see, I’ve left out countless other pieces of the overall puzzle.)
It’s interesting to me that we actually believe that it is us doing what we seem to do. It is interesting to me that matter - the amalgamation of quantum, dimensionless particles into the phantasms we believe to be physical things - are actually
real to us. That what we sense are essentially holograms we believe. It is interesting to me that we can’t create or destroy matter. It is interesting to me that neither can the universe. It’s interesting to me that the universe expands as it does (or,
seems so to us). It’s interesting to me that all of it is really not any different - in its moment to moment quantum projection - than our little boy, moving the stone along the walkway - extending to him through a process of countless ‘chance’.
If only a few ‘chance’ events had failed to take place, if only a countable number in a countless and infinite sea of chance occurrences, had not taken place, this reality would be un-perceived.
Chance, not homogeneity, but
chance. Chance with a deck of universe (or larger) proportions. Chance with preposterous odds times a preposterous number. It’s preposterous to think that
matter did it. It’s preposterous to think that
space did it, unless Space is not what we think it to be. But, we like to define “space” using a negative word. ‘Space’, we say, is
extension - between bodies, I presume. ‘Space’ is not a medium - it is merely an
extension -
an absolute absence, the proverbial philosophical
nothingness.
Aquinas, after Aristotle, thought of
space as a mathematical entity, as the sum of the extensions of all of the bodies of the universe. But, we tend to think of it as some kind of medium - which, for Physics, it is. It is that where quantum stuff resides. But, this just creates another problem: if it is not a
medium, in every sense of that word, then it is “nothingness,” and no thing can have “place.” So, we have to come to terms that
space is not a quantum ‘foam’.
God bless,
