Re: Causality vs Entailment



Judith,
 
I re-read p. 10 and I see nothing to change my mind. On the contrary, even section 3G is entitled "Entailment in the Ambience: Causality". That to me says it all. And, later in that section:
            "In this way, entailment relations between phenomena are subsumed under the general framework of causality."[LI p.57, ital. orig.],
and later:
            "We shall thus accept this view, that entailment relations can exist between phenomena and that their study comprises causality; hence science and causality are too that extent synonymous."[LI p.57]
 
I agree that we learn about causal entailments by virtue of the observations of phenomena of which demonstrate such relations. And I take the view that this study comprises causality. In my view, we have no scientific basis for supposing that there exist "underlying entailment patterns" which exceed those which we are able to observe either directly or indirectly (i.e., as in a "hidden variables" kind of way - see The Limits of the Limits of Science p. 87-88). If we have evidence that such additional entailment relations hold, then that is because we have phenomena on which to base that claim; that relation is thus part of causality. If we have no evidence, then we have no basis for asserting that some additional causal entailment(s) exist. By the same token, an absence of such evidence is not proof of the non-existence of additional causal entailments, so we always have to leave the door open to the possibility of uncovering additional entailments. Likewise, such additional evidence can lead to a revamping of our understanding of previously known entailments. I consider any such undiscovered causal entailments to fall under the heading of causality, as I would consider undiscovered stars to fall under the heading of astronomical objects, for in either case, the existence of either a causal relation or a star is borne out only insofar as there arises phenomena to indicate that existence, and such evidence places their existence into those respective categories.
 
Regards,
Tim

Tim, re-read the bottom of page ten; the "summary" of the Praeludium, in Life, Itself. Causal entailment is what you're after, not causality. Causality is how we learn about entailment. That's our only avenue into the underlying entailment patterns, which ultimately (it is hoped) can teach us about Natural Law. There are many explanations which can seem to account for the behavior of systems in the universe and, in fact, this is precisely how science has arrived at the point it currently is at: both good and bad. Finding an explanation for causality that seems to commute in one kind of system but not another.... That's where we are "at" right now. Robert Rosen's assessment of this situation was that we don't have the entailments right.
