If there are variations of ability between men then there must be some means of comparing them to each other beyond the horizon of personal experience. — Valentinus
You will have to show how that problem of epistemology relates to Plato's actual argument in the dialogue. I don't see why I have to be the only one reading the dialogue in our discussion. — Valentinus
Knowledge can be a problematic word when applied to animals. Innate dispositions might be better. The have a nature such that when an object induces in the animals the relevant sensory organ, they recognize the object as food or predator or mate, etc. — Manuel
Yeah. So far as we know it's the chemical properties that cause us to smell objects the way we do. At least we have to include chemicals as an important part of the explanation.
I think Srap Tasmaner was on to an important point, which is the similarity of our reports based on different senses. We often see that sight and touch seem to agree with each other, as when we crumple up a piece of paper and aim for the garbage bin.
But sometimes the reports don't match, a piece of Tupperware may look normal to us and we would expect we could lift up with no problem. Until we touch it and feel an intense burn. — Manuel
Depends on how you think of objects. Something lacking all sensible properties could be called nothing. — Manuel
But vowels and consonants are by definition speech sounds, and written letters represent them. If there's no need to represent speech, neither consonants nor vowels are required in the alphabet or whatever. — jamalrob
That proposition is addressed and deemed inadequate in the Theaetetus starting at 200d. — Valentinus
The future is within our grasp given the laws of nature are universal and constant - a good basketball player can, if he's skilled enough, score.

That observation is also made by Socrates to note that Protagoras' use of each person's experience as an adequate measure does not account for differences in ability amongst men. — Valentinus
According to the Fragments of Heraclitus, you would not be able to affirm or deny the proposition:
Hesiod distinguishes good days and bad day, not knowing every day is like every other. — Valentinus
And you would be too busy fighting to care:
It should be understood that war is the common condition, that strife is justice, and that all things come to pass through the compulsion of strife. — Valentinus
Change is the only constant. — Heraclitus
C'mon, MF. Think a little bit. English is spoken even as a first language around the world, so what is the correct pronunciation of "schedule"? Or "controversy"? And so on. And can you understand it as it's spoken around the world? I cannot. And never mind where it's spoken as a second or third language.
Ancient Greek was a lingua franca of the ancient world from west of Sicily to the border of Afghanistan. Do you imagine in that world it was pronounced the same from one end of that world to the other?
However yhwh was pronounced, on those occasions when it was pronounced (which was when, according to your sources?), would have been correct. — tim wood
Based on the spoken word. — Hermeticus
By and large we apparently don't. I think there are really unusual boundary cases, sure, just as real people do face circumstances that can overcome their commitment to self-preservation. But the evidence says people will put up with a lot. — Srap Tasmaner
This is not a scientific answer. It is about answering questions through experiments. In philosophy also through thought experiments.
What is then your gut feeling to dark matter? Why research? We'll just ask you — SolarWind
A little something to ponder upon:
1. We don't know the answer to "are we alone?"
but,
2. If there are aliens, we know the answer to their question, "are we alone?" No, definitely not!
I propose a new question be formulated: are they (aliens) alone? No! — TheMadFool
Moreover, the 2nd incompleteness theorem is about formal provability of consistency and does not itself say anything directly about knowledge, which is a philosophical issue, not covered by the mere mathematics of Godel's proof.. — TonesInDeepFreeze

Yes, I think you raised an important point, the arbitrary aspect. What would be rational to expect of something to smell like? We begin (almost) already in it, we grow up to an age in which we just assume meat smells this way and no some other way, and that flowers smell like this.
But as to what they should smell like, based on how they appear, is a good question which I don't have an answer for. — Manuel
Working my way through my confusion. I mean, sure, objects don't need to many properties by necessity. If you are blind and deaf and lack a sense of tactile sensations, there aren't many properties to uncover.
Properties being, properties for us: induced by objects so that we feel that way we do when we encounter them.
But to expect a property-less object is perhaps going too far. — Manuel
Sure, the point of this specific thread is just for that, whatever one wants to make of it. — Manuel
I think its innate, it's something they are born with, they have the disposition to recognize grass as a type of food. Similarly, baby turtles race to the ocean as soon as they hatch. There's no other explanation that an innate mechanism that makes them go to the ocean. — Manuel
Blind people have said that they are aware that "being in the red", means losing money. Or "feeling blue" means feeling down or depressed. If they could see, would the sensation of seeing an apple or seeing the ocean resemble anything associated with the word? I suspect not. But don't know, obviously. — Manuel
As far as I have seen, which, admittedly isn't far, the inconsistencies in math are analogous to "This sentence is not true." The proof of Godel's first incompleteness theorem uses similar slight of hand to show that, as Wikipedia says:
...no consistent system of axioms whose theorems can be listed by an effective procedure (i.e., an algorithm) is capable of proving all truths about the arithmetic of natural numbers. — T Clark
From what I've read, the foofaraw about these ideas comes from the fact that they crush logician's and mathematician's dreams of a perfect formal logical system, not from any impact to any mathematical system that could have an impact on the real world.
Am I sure about this? No way, but it seems like that's what Wittgenstein was saying in the linked article that Banno provided. Is it possible I have misunderstood? You betcha. — T Clark
That's an excellent illustration of the general idea. Thanks for sharing. — Manuel
This whole discussion started from the question of whether the liars paradox has any implications for the design of bridges, i.e. if the paradox undermines the basic aspects of using math to solve problems. Thoughts? — T Clark
Not quite, but it's an approximation. Assume that for some reason, you recover all your senses. Before you lacked all of them.
Before you become habituated to the world, things like the distance of objects, what sound is related to which object, how surfaces feel, would likely be completely foreign. One would have to spend some time to associate the sound of footsteps with people stepping on the floor, as opposed to someone knocking on the door, which sounds kind of similar, depending on certain conditions.
But you may be right, I may be puzzling over nothing. I just found it interesting, but am not quite able to express it well enough, maybe because I'm wrong. — Manuel
Yes. But what about chemical composition is it that should lead it to produce the experiences that we do? When I look at a chemical, say a sleeping pill or a hallucinogenic, it isn't obvious to me that these things would cause me to feel the way I end up feeling.
We find these things natural because we are habituated to them by now.
It's the difference between the felt quality and configurations of particles which lack any apparent qualities associated with our everyday life. — Manuel
