Re: Causality vs Entailment



Judith,

 

From that page in Essays:

 

In either case, there are never enough purely behavioral discrimina-

tors that entail identity.We must go to causality for that kind of identi-

fication—i.e., into how behaviors are generated. One immediate con-

clusion is that we cannot generally argue backward from behaviors alone

to their causal bases (i.e., analysis and synthesis are not simply inverse

operations [see chapters 1 and 6]).Behavioral mimesis is at best only

evidentiary; it has been argued that inductions from such evidence, like

the Turing Test, have no basis, since at least the time of Hume. [ital. orig., bold added]

 

 

To say that the problem is that it is “a linear _expression_ and a linear view” is simply a restatement of “analysis and synthesis are not simply inverse operations”, where “linear” refers to the synthetic. Since each is not just the inverse of the other, one does not entail the other.

 

Regards,

Tim

Tim you're getting into quicksand, here. My father did not say this the way you are representing it. All of science argues backwards from effects to causes. The problem is that such an argument is a linear _expression_ and a linear view. That is precisely what limits "causality" as a subject for study. The underlying entailment relations don't follow this linear, timebound form and are, therefore, more comprehensive.

Hi Steve,

I think one general point about mimesis Rosen makes is that And an accretion of behaviors does
generically entail a particular accretion of causes. Analytic models are not
generically  the inverse of synthetic models. Thus to create something which
mimics the behavior of some original system does not entail that the mimic
therefore has the same underlying causal entailment organization - it's
causal basis - as the original system. So mimetic approaches will
generically result in a lack of synonymy of entailment structures between
the two systems.

With respect to simulations, there is again the problem that that there is a
lack of synonymy of entailment structures between the original system and a
simulation of it. In a simulation, all the entailment structures are
collapsed into material cause (i.e., software program) to a simulator (i.e.,
hardware). Additionally, the simulator does not decode into anything in the
original system: it is entirely extraneous to the original system yet
entirely integral on the simulation side.

In both cases, I feel the term 'entailment' is used consistent with the way
he uses the term elsewhere.

Regards,
Tim
