Interesting statements on motion and rest; on a non-natural movement that is not violent, i.e., the movement of the spheres.

The quotes below are from q. 91 of the supplement to the Summa theologiae.

Since Aquinas didn't have a concept of momentum, he thinks the movement of the spheres has either a an angelic or a supernatural (in the strict sense) cause. That is problematic, but he allows for an openness of natural things (like spheres) to direction by reason in a way that is consistent with his notions of natural/unnatural&violent. That is interesting and worth pondering

"... things that are directed to the begetting of men, such as the movement of theheaven and the variations of the elements... every body that is moved naturally has a place wherein it rests naturally, whereto it is moved naturally, and whence it is not moved except by violence. Now no such place can be assigned to the heavenly body, since it is not more natural to the sun to move towards a point in the east than to move away from it, wherefore either its movement would not be altogether natural, or its movement would not naturally terminate in rest... the heavenly bodies serve man by their movement, in so far as by the heavenly movement the human race is multiplied, plants and animals needful for man's use generated, and the temperature of the atmosphere rendered conducive to health. Therefore the movement of the heavenly body will cease as soon as man is glorified."

"...every body that is moved naturally has a place wherein it rests naturally, whereto it is moved naturally, and whence it is not moved except by violence. Now no such place can be assigned to the heavenly body, since it is not more natural to the sun to move towards a point in the east than to move away from it, wherefore either its movement would not be altogether natural, or its movement would not naturally terminate in rest... the heavenly bodies serve man by their movement, in so far as by the heavenly movement the human race is multiplied, plants and animals needful for man's use generated, and the temperature of the atmosphere rendered conducive to health."

"Movement does not belong to the perfection of a heavenly body, except in so far as thereby it is the cause of generation and corruption in this lower world: and in that respect also this movement makes the heavenly body participate in the Divine goodness by way of a certain likeness of causality."

"... although immobility is simply nobler than movement, yet movement in a subject which thereby can acquire a perfect participation of the Divine goodness is nobler than rest in a subject which is altogether unable to acquire that perfection by movement.

"In a heavenly body there is no potentiality that can be perfected by place, or that is made for this end which is to be in such and such a place. But potentiality to situation in a place is related to a heavenly body, as the craftsman's potentiality to construct various houses of one kind: for if he construct one of these he is not said to have the potentiality uselessly, and in like manner in whatever situation a heavenly body be placed, its potentiality to be in a place will not remain incomplete or without a purpose."

"...a heavenly body, so far as regards its nature, is equally inclined to every situation that it can possibly occupy, nevertheless in comparison with things outside it, it is not equally inclined to every situation: but in respect of one situation it has a more noble disposition in comparison with certain things than in respect of another situation; thus in our regard the sun has a more noble disposition at daytime than at night-time. Hence it is probable, since the entire renewal of the world is directed to man, that the heaven will have in this renewal the most noble situation possible in relation to our dwelling there..."

Dembski's "specified compexity" semiotics and teleology (both ad intra and ad extra)

Integral to Dembski's idea of specified complexity (SC) is the notion that something extrinsic to evolution is the source of the specification in how it develops. He compares SC to the message sent by space aliens in the movie "Contact." In that movie, earthbound scientists determine that radio waves originating in from somewhere in our galaxy are actually a signal being sent by space aliens. The scientists determine that these waves are a signal is the fact that they indicate prime numbers in a way that a random occurrence would not. What is interesting to me is the fact that Dembski relies upon an analogy with a sign rather than a machine. Like a machine, signs are produced by an intelligent being for the sake of something beyond themselves. Machines, if you will, have a meaning. Signs, if you will, produce knowledge. But the meaning/knowledge is in both cases something other than the machine/sign itself. Both signs and machines are purposeful or teleological

continuing the discussion with Tim in a new post

Hi Tim, I am posting my reply here, because the great blogmeister won't let me put it all in a comment. Me thinks I get your point: is it that we can name and chimps can't, so therefore we are of greater value than chimps? Naming is something above and beyond what a chimp can do, right? In other words, you are illustrating the point I am making (if I catch your drift). My argument is only a sketch, but I think adding the ability to name names, as it were, is still not enough to make the argument seem cogent. For one can still ask why we prefer being able to name over other skills had by animals but not by humans. The objector would demand a more convincing reason. The answer I have in mind is, to put it briefly, that there is something infinite about human beings in comparison with the subhuman. That "something" has to do with our ability to think of the meaning of the cosmos. Whereas one might say"He's got the whole world in His han

particular/universal event/rule

While listening to a recorded lecture on Quine's Two Dogmas of Empiricism, it occurred to me that every rule is in a way, a fact about the world. Think about baseball: from the p.o.v. of an individual player, a baseball rule is not a thing but a guide for acting and interpreting the actions of others. But this rule, like the action it guides, is part of a concrete individual --i.e., part of an institution that has come into existence at a particular place and time, has endured and may eventually go out of existence. The baseball rule, as a feature of that individual, is likewise individual. The term "baseball rule," on the one hand, links us to a unique cultural event; it can, on the other hand, name a certain type of being. In this way, it transgresses the boundary between proper and common noun. If there were no such overlap, then we might be tempted to divide our ontology between a bunch of facts "out there" and a bunch of common nouns "in here.&qu
