I bumped this to the top of the queue because I added another (very interesting) video at the very end, where Searle sets up an analogy between building an artificial heart and building and honest-to-dog artificial brain.
Here’s a video in which John Searle discusses AI with Luciano Floridi. I haven’t watched Floridi’s section, nor the discussion afterward. Here and now I’m interested in a distinction Searle makes, starting at about 9:12:

He points out that the distinction between objectivity and subjectivity has both an ontological and epistemic aspect, which is generally neglected. This is VERY important. He uses it to clarify what’s doing on when we worry about whether or not or in what respect computers can be said to think, or be intelligent. That’s a complicated and worthwhile discussion and if the topic interests you, by all means listen to what Searle has to say.
My immediate interest is somewhat more restricted. For some time now I’ve been complaining that, unfortunately, “subjective” has come to mean something like “idiosyncratically variable among different individuals.” But a more basic meaning is simply, “of or pertaining to subjects.” Well, Searle informs me that I’m distinguishing between “subjective” in the epistemic sense (idiosyncratically variable) and “subjective” in the ontological sense.
Ontologically, subjectivity has to do with existence, being experienced by a subject. The experience of a literary text is certainly subjective in this sense. And, as the meaning of texts depends on experiencing them, meaning must be subjective as well. This is a matter of ontology.
Claims about the meaning of a text must necessarily be observer relative and so those claims are epistemically subjective. There are no objective claims about the meanings of texts, though some claims may well be intersubjectively held among some group of readers (an interpretive community in Fish’s sense?).
My claim about literary form is that it is an objective property of the interaction between texts and readers. It is thus not subjective in either the ontological or epistemic senses. By studying the form, however, we can learn about how literary subjectivity works. For literary subjectivity is a real phenomenon of the human world.

You might want to look at this talk Searle gave at Google in December of 2015, where the first question was asked by Ray Kurzweil:
The really interesting stuff starts at about 32 minutes in, where Searle sets up an analogy between building an artificial heart and building a brain that can REALLY think. Searle points out that we know enough about how the real heart works so that, sure, we can build an artificial heart. There's no reason, in principle, why we couldn't build an artificial brain that thinks and is conscious just like real brains. Alas, we don't know enough about real brains to even begin this process.
Kurzweil asks his question at 38:58.
So if I understand, the sentence "That is amazing" has a subjective ontological framework whereas "That is amazing to me" has an objective one.
ReplyDeleteHmmmm.... Amazingness is surely a subjective phenomenon, that's ontology. So, your first statement is about something that is ontologically subjective.
ReplyDeleteOn the second statement, if it is true that you've said that and all observers agree on it, then it is epistemologically objective that you made that statement. But then whether or not you've made some assertion, any assertion, is ontologically objective as well. But neither of those judgments contradicts the fact that amazingness is subjective, and it's subjective for you as for anyone else.
OK, so "objective" in "epistemologically objective" basically means "algorithmic" rather than "intrinsic".
DeleteAs for my earlier comment, although whether something is amazing is a matter of opinion, surely whether something is amazing to a certain person is a matter of fact. After all, the statement "That machine is amazing to Bob" is inherently false if Bob is not in the least bit amazed by it. If he is, though, it would seem that statement is ontologically objective in that it treats the machine and Bob as a "system", to which relation being described is intrinsic.
I don't know what "algorithmic" vs. "intrinsic" means.
Delete"whether something is amazing to a certain person is a matter of fact. " Agreed, that's what I said. But the fact that Something is amazing to Person X, while being epistemologically objective, does not imply that Something is ontologically objective. It is still ontologically subjective. The epistemological objectivity applies to the fact Person X believes it.
Well, "objective" can mean intrinsic or inherent to the object, or it can refer to producing the same result no matter who does as in a test being objective because it produces the same score for the same answers no matter who scores it. That would be the case if the scoring follows a well defined set of instructions on how it is to be scored.
