...if 'true' is a category of belief, then nothing about the real world determines what goes in that category, it's a human-made one. We decide what's in and what's out. Like 'blue'. — Isaac
If we have no reasonable grounds or mechanism by which the two could be assumed to be the same then we must conclude that they would only be so by chance. — Isaac
I've been with Nancy for 38 years. We met on a blind date set up by a friend. Haven't been apart since...and I would not change any of the memories I have of this monogamous relationship.
ASIDE: We've been together, as I mentioned, for 38 years...and have never married. We've both just felt that no governmental agency or church need be involved in our relationship. — Frank Apisa
here's an example of you using that sense of the word measure:
According to this criterion, it would make sense to say that a mantis shrimp's eyes are measuring light frequencies and distributions...
— creativesoul — InPitzotl
I was referring to metaphysical antirealism which is the idea that "nothing exists outside the mind" — Michael McMahon
Why is medicare for all a bad idea? — frank
Mantis shrimp's eyes measure... what they measure. The question is what they measure. I define color in terms of what eyes measure in color vision; that's the colorimetric definition — InPitzotl
You're still confused over the same point. There are three completely distinct things here: (1) frequency, (2) spectral distribution, (3) color. — InPitzotl
That's incorrect. As you yourself say, "photoreceptors are just doing what they do". And what they do, with respect to responding to light, is send signals proportional to some amount of isomerization of photopsin molecules that they contain. That's it; nothing else. That thing is (3). And if (3) cannot distinguish between spectral distributions (2), then (3) cannot be said to measure which (2) you have. If (3) cannot distinguish frequency components (1) in a spectral distribution, (3) cannot be said to measure frequencies in a spectral distribution. (3) can do neither of these things, so it measures neither.
To reach your conclusion from the assessment requires conflating (3) with (1) and (2). My assessment contains no such conflating; that's all on you. — InPitzotl
If that were true then measuring requires only detection (3), reception, excitation, folding, and/or perception. According to this criterion, it would make sense to say that a mantis shrimp's eyes are measuring light frequencies(1) and distributions(2)...
— creativesoul
That's incorrect. — InPitzotl
I've a hard leaning towards methodological naturalism

There's nothing supernatural about necessary truth, such as that which is expressed by mathematics. — Douglas Alan
If and when we meet space-faring aliens, I guess it will come to you as quite a surprise to you when they have "invented" the same math that we have. What will explain that, prey tell? — Douglas Alan
The number three is not a name, it is an abstract entity that represents certain properties of a certain quantity. — Douglas Alan
The predicate P that picks out chairs, existed as an abstract object in the space of predicates long before people existed. — Douglas Alan
I couldn't disagree more. Logic, like math, is discovered, not invented. Though I believe that everything that is invented is actually a form of discovery. — Douglas Alan
The number three would exist, even if there were no intelligent beings to comprehend the number three. Likewise, the predicate P that picks out chairs exists, even if there were never any humans to breathe life into P. — Douglas Alan
...we measure with this photoreceptor... — InPitzotl
The set of all chairs is the set of all x such that P(x), where P is a predicate that is true for chairs and false for non-chairs. — Douglas Alan
I'm still struggling a little bit here, particularly when I perform a substitution of terms with your proposed referents/definitions for those.
— creativesoul
Okay, but I'm a bit confused why you're struggling: — InPitzotl
I guess to me, to say that something exists is merely saying that there is a predicate that when applied to everything yields some results. — Douglas Alan
There are three completely distinct things here: (1) frequency, (2) spectral distribution, (3) color. — InPitzotl
Since what matters for detection is simply the raw number of photopsin events, and there's multiple ways of reaching that number, then we're not detecting (2)'s; we're detecting "numbers of events".
— InPitzotl
This bit leaves me a bit confused though. When you say that "we're not detecting (2)'s; we're detecting numbers of events" are you referring to us or the photoreceptors under consideration? — creativesoul
Sort of (changed from yes); I'm referring to the number of photopsin molecules (available for detection). (2) has a particular effect on our eyes. A different (2) could also have the same effect on our eyes. So call the former (2a), and the latter (2b). The effect is (3x); (2a) would have effect (3x), and (2b) would also have effect (3x). Since we can't distinguish (2a) from (2b), it doesn't make sense to say that we detect (2a). What we detect instead is (3x). 3x is "an equivalence class of spectra". 2a is just a member of that equivalence class. 2b is another member. — InPitzotl
I don't consider chairs to be existentially dependent on us. Chairs would exist even if we didn't. — Douglas Alan
I would argue that it is the same with colors. Color vision is far from only in the eyes. There is a lot of cognitive processing that is unique to humans that goes into our color vision. And even if it were the case that all of human color vision were determined only by our human eyes, the eyes of all animals and potential aliens are going to work differently and classify crayons differently. — Douglas Alan
You're still confused over the same point. There are three completely distinct things here: (1) frequency, (2) spectral distribution, (3) color.
Photons hit spots on our retina; but they aren't confined to having single frequencies (1's); they have distinct frequencies. But there's some distribution of them depending on what you're looking at... more at some frequencies than others. Because each photoreceptor is sensitive to a range of frequencies, then it's the entire distribution (2) that matters, not individual frequencies. But a given photoreceptor is simply more sensitive to some frequencies than others... at the photopsin level, it either folds or doesn't, but just has a probability of folding per photon based on the photon's frequency. That means you can make it fold with a given probability in multiple ways; you can fire less photons at the more sensitive frequencies, or more at the less sensitive ones. — InPitzotl
Since what matters for detection is simply the raw number of photopsin events, and there's multiple ways of reaching that number, then we're not detecting (2)'s; we're detecting "numbers of events". — InPitzotl
I don't think Trump will agree to debate. He has said as much. Why would he risk it? — Monitor
It makes completely sense if they prefer Bernie. And why wouldn´t they?
In the event, everybody is meddling in everybody elses affairs, so the this fake meddling hysteria is complete nonsense. — Nobeernolife
Depends I guess. If one holds to the classic (simplified) conception in which truth can only be predicated of propositions while facts simply are states of affairs (words vs things, roughly), then even to speak of 'true facts' is a kind of category mistake, or, like false facts, simply a mode of expression which is simply speaking a tautology (a 'round circle'). In this scheme one might say truths express facts or somesuch. — StreetlightX
...philosophy to be mainly 'talking about talking', which in all fairness, does comprise a very large percentage of what goes on in this forum, too. — Wayfarer
How many would act morally if the law did not exist?
A number of prominent analytic philosophers are Protestant, Catholic, or Jewish, and others, such as Wittgenstein and Rawls, clearly had a religious attitude to life without adhering to a particular religion. But I believe nothing of the kind is present in the makeup of Russell, Moore, Ryle, Austin, Carnap, Quine, Davidson, Strawson, or most of the current professoriate.
I don’t understand those who decry “big business” and lobbying. The only reason people buy out politicians and bureaucrats is because politicians and bureaucrats can be bought. We should decry the politicians and bureaucrats for setting the conditions. If they didn’t accept bribes and certain lobbying that sort of business would become untenable within a few years. — NOS4A2
've can't keep track of what the disagreement here is precisely anymore. Why don't we table the discussion on whether there are colors for a moment and address an easier question: Are there chairs? — Douglas Alan
One might as well speak of true lies (not impossible, but very ugly). — StreetlightX
