An odd argument I came across recently:
1. if the universe was temporally infinite, then there would be no 1st moment
2. if there was no 1st moment, then there was no 2nd moment
3. if there was no 2nd moment, then there was no 3rd moment
4. ... and so on and so forth ...
5. ... then there would be no now
6. since now exists, we started out wrong, i.e. the universe is not temporally infinite
EDIT: Post 17 or thereabouts below has an extended rendition of the argument
Sound argument? — jorndoe
A "logical principle" is an idea. There are no logical principles outside of our heads. There are processes that are lawful in that they are consistent and causal and it is our minds that categorize these processes under "logical principles". I find that humans are often not logical. They have trouble integrating their beliefs from different domains of knowledge into a consistent whole. Remember what I said about our brains being modular?You asked me what form "logic takes." Earnestly, that question was meaningless to me. Weren't you really asking what form my experience takes when I note that I'm being logical?
Surely you aren't proposing that a logical principle is identical to any one experience of its application. One can only accept that at the cost of defying logic. — Mongrel
Notice how you described a logical process visually. Thanks.What form does your logic take in order for you to know that you are being logical - for you to be able to observe your own mental processes as being logical? — Harry Hindu
I would describe it as processional like a parade or constructive like a building project. Being logical has the character of walking one step after another. Or it's like mortaring bricks where each one is sturdily stacked on the last (which is why I would describe a really solid logical argument as a brick house.) — Mongrel
I think you're being purposely obtuse, but I'll ask it a different way.I don't understand the question, Harry. Could you explain it to me? — Mongrel
Principles are expressed by utterances of sentences. One is free to take it on faith that a particular expression is understood in the same way by two different people. Question is: can you prove it? — Mongrel
Sorry, can't help you Harry. I don't know what the hell you're talking about. — Mongrel
And my point is that you must have had some sensory experience in order to reason. If you didn't then what form does your reasoning take? What is it that you would reason about?Point is that you must have had confidence in basic principles of reasoning in order to accept evolution. Therefore it doesn't make sense to say that observation of the ways of evolution provides you with that confidence. — Mongrel
We've already been over this, Wayfarer. Several others mentioned mathematics also which I already showed that you need a visual experience of symbols, like numbers, to do math. Try doing math without having seen any numbers, or a number of things, to then add, subtract, multiply, and divide. How would you know to perform these operations without seeing symbols like +, -, *, and /?I took issue with intitial statement 'every idea is composed of some sensory impression'. I gave mathematics as an example but there are many others - see this. — Wayfarer
I could say the same thing about what you said about Plato. - "Right, 'Plato says', so it must be true.Right! 'Darwin says', so it must be true! Alfred Russel Wallace, co-discoverer of the principle of natural selection, never accepted that h. sapiens intellectual abilities could be explained by Darwinian principles. — Wayfarer
If your only argument is that my explanation is to simple then I take that as a compliment. — Harry Hindu
OK then, I meant 'simplistic'. — Wayfarer
Then you're not familiar with modern theories in neuro science and psychology.I'm not familiar with modularity in brains. — Mongrel
Exactly - just as the number and kinds of sensory devices you have reduce the number of possible outcomes in your mind and create an innate tendency to think in sensory impressions (symbols). Do the symbols lean us toward the truth? Darwin says we an rely on that because of natural selection also fine-tuning the mind to interpret these symbols in ways that allow the organism to survive and procreate in a dynamic environment.We can tell that math isn't straightforwardly innate because there wouldn't be any such thing as a math class if that was true. That's one prong of Locke's attack. The other prong is to say that if Leibniz (and others) are saying that humans have a potential to acquire knowledge, then the thesis is trivially true.
Leibniz says it's something else. He uses the tabula rasa image, but says we should imagine it as marble with streaks running through it. Any statue can be cut from plain marble, but the streaky kind will reduce the number of possible outcomes... in like manner, the mind has an innate tendency to think along certain lines.
But do the streaks lean us toward the truth? Descartes says we can rely on that because of God's benevolence. For Leibniz, it's more that the human mind is a reflection of the divine mind. — Mongrel
So it is the case that we are born as individuals who are raised and shaped by society/culture/linguistic input (that itself originates from historical development/established norms and institutions). Humans, for the most part, need society to thrive. Let us say there are two main responses to this:
1.) The responsibility to work with the established group norms, institutions, and settings are foisted upon the individual, and thus, one has been forced into the situation. Though one may feel a personal obligation out of enculturated habits and personal preferences it is not anything more than an individual preference or habit of thinking.
2.) The responsibility to work with the established group norms, institutions, and settings are foisted upon the individual, and thus, even if one is forced into the situation, since the group shaped/shapes the individual, and the group, by-and-large, is also part of the reason the individual can survive and thrive, the person should feel a sense of duty to the established group.
Which is closer to the more accurate view? — schopenhauer1
Philosophically speaking, what do bear attacks, anatomy, chemistry, physics, office work, aliens, foraging societies, and technology have in common? — schopenhauer1
That all depends on the social environment one finds oneself in. People who lie and don't get caught can usually get what they want, but it's that part about getting caught that can throw a wrench into things.Why should I be honest? Everybody lies, and people who lie are usually better at getting what they want. Wouldn't it be more logical from an evolutionary standpoint to be a liar? — MonfortS26
How do we know that these other ideas are "unconscious"? Our brains are modular and we could have several different parts forming different concepts with different data.Consciousness is always of something. It isn't clear that all thought and ideation are necessarily conscious. I think nativism is counting on the existence of unconscious ideas. If such a thing exists, how does that work? — Mongrel
No. That's not all my post says. Defining these terms would certainly be a starting point and would build a good foundation for what we are talking about. If you have better definitions then by all means, provide them instead of just putting words in my mouth.Basically your post says 'hey, all we need to do is define 'ideas' and 'knowledge'! - and then you proceed to do that, as if you can compose a forum post, and basically wrap up the entire curriculum of philosophy. They're deep issues - Plato's dialogue on the nature of knowledge presents various definitions but ultimately leaves it an open question. — Wayfarer
I'm not disagreeing that the ability to organize sensations isn't less inherent in the nature of the mind than the sensations themselves. Without either there would be no mind. It would be like saying you could boil water without any water.I'm not 'conflating' anything. Without the ability to organise sensations, then what kind of ideas could you form of anything? It's not simply a question of 'recieving sensations' and 'learning by experience' - the mind has innate abilities and capacities of many kinds, which constitute ideas. Now, whether that means that we're born with ideas, is another question, but what I am arguing is that we are not born 'tabula rasa', as Locke says, and we don't accumulate knowledge solely through experience or sensory impressions. — Wayfarer
But the "effects" of God are visible to the eyes. The effect (like your existence) is what needs to be explained and your mind seeks explanations for virtually every thing experienced. Declaring God not to be visible to the eyes is just and assertion made by believers to make their God unassailable by science. I don't understand how anything that you know or think of isn't a composite of elements taken from the senses. If God isn't a composite of elements taken from the senses, then what is it and how do you know it even exists?But God is not visible to the eyes, and the thought of God is not a composite of elements taken from the visible world, so your assertion seems to contradict itself. — John
Are you saying that these blind and deaf mathematicians were born knowing mathematics, or were they taught it? If the latter then how did they learn it - if not by using their available senses? Braille and sign-language are just different forms of language using different symbols for different senses.There have been notable blind mathematicians. In fact last time this came up, I think I discovered some notable deaf-mute mathematicians. But regardless, your depiction of what constitutes knowledge is so simplistic, that it is barely worth debating. — Wayfarer
Try doing either without any senses.That is a good example, but then you could have picked just about any concept in science or mathematics. — tom
Where did the idea of God come from then? — John
And what sensory experience leads you to posit the square root of -1, pray tell! — Barry Etheridge
Do you believe in such a thing as an innate idea? Or are ideas always built up from experience?
Leibniz believed that principles of math are a clue. Though he granted that knowledge starts with the senses, he didn't believe that's enough. He pointed to the expectation one has that a principle is universally true. Instances of sensory experience can't account for that kind of expectation. — Mongrel
Well, that depends on how you define, "meaning". Some have already claimed that "meaning" refers to some end goal. The problem with this is that one can fail at achieving a goal, so the end goal can't be the cause of life as it exists. If it were, then all goals would be achieved. Also, there is no end goal for the universe, or life in it. Goals only exist in minds which places value on everything in how it helps or hinders achieving one's goals. Values are derived from the present goal. Does the universe have a value system based on some goal?Does it make sense to assign a (universal, not personal) "meaning" to "life"? Or has the question always been a category error? — hypericin
Why would the robot need to experience blue in order to know what blue represents? Why couldn't it represent a 475nm wavelength of EM energy with some other symbol in it's memory and still "know" what the scientists "knows"?The curious case of the robot and the scientist.
Consider a faulty scientist and a faulty robot. The scientist is an expert in light, but was born with a rare condition affecting her optic nerve, that makes it unable to transmit blue light signals. The robot has a loose wire, so it too is unable to transmit blue light signals from its camera. The scientist is fixed by a doctor, and the robot is fixed by an engineer.
So, what has changed? Both the robot and the scientist can now recognise blue and are able to use that recognition to perform certain tasks. Both the robot and scientist experience blue.
But, only the scientist now *knows* what it is like to experience blue, the robot does not. There are also a couple of curious aspects of this experience that she notices - she, despite her extensive knowledge, could not predict what the experience was going to be like, and she can't describe it either.
Only the scientist possesses the quale of blue.
It seems a bit easy just to deny qualia exist, rather than recognise there is a potentially deep philosophical problem to solve. — tom
I think it is anthropomorphic to claim that all non-human animals don't possess consciousness to some degree. When we share nearly 99% of our genes with chimps, what is it about that 1% that prevents the chimp from having consciousness? How do you explain how a chimp can know that when another chimp is staring in another direction, then they look in that direction too. This must mean that they can model other chimps' mental activity - that they know that other chimps have access to information that they might not until they look in the same direction.But where is the "terminus"? Both robot and scientist are being affected by blue light - i.e. some atoms are being affected.
We know, via computational universality, that consciousness *cannot* be a peculiarity of an exact state of matter.
Also, depending on how you define consciousness, there exist conscious entities that don't possess qualia - e.g. all non-human animals.
The fact remains that qualia are unpredictable and indescribable - very odd indeed! — tom
Exactly.Uhh? Duh! — tom
Uhh. By using science. Duh!Really? So how would you set about testing and falsifying a philosophical theory? — tom
The Democrats have done more to deny their own voters a voice by what they did to Bernie.Ironic. Trump claims the elections are rigged (against him) but it is the fact that they are rigged (to sustain a two party system) that has allowed someone so despised as he to have any chance at all of winning the presidency. As many of his voters will be voting against the other (also widely despised) candidate as for his candidacy. It's doubly ironic that most of the rigging is on the conservative side in working to deny likely Democrat voters their suffrage. But this is like Trump's complaints against the media - what he rails against is very often what has got him where he is. — Baden
...and in my next post, I admitted that people can use the term, "world" to mean/refer to different things. When are you going to get over something I said before and then corrected myself in my next post and start defining what you mean when you use the term, "meaning", so we can then get on with the discussion?No, in your first post you said "To me, the world is all that is" and "If someone claims that the world isn't all there is, I would make the claim that they are misusing terms."
You're saying that it's wrong for someone to use the word "world" to refer to something other than "everything that exists". I'm asking you to defend this assertion. — Michael
You keep bringing it up. I'm trying to get you to understand the point I was making in the actual thing that people refer to when they use some term to refer the entirety of what exists. Who cares what symbols people use to refer to it?"The President of the United States" and "the husband of Michelle Obama" mean different things even though they refer to the same person.
And to bring up an earlier example, "human" and "intelligent species" mean different things even though they refer to the same things (assuming no extraterrestrial life for the sake of argument).
Although I don't see how this is relevant to this discussion. — Michael
Religion is subjective which includes seeking truth through faith and revelation. Science is objective, making use of methods of investigation and proof that are impartial and exacting. Theories are constructed and then tested by experiment. If the results are repeatable and cannot be falsified in any way, they survive. If not, they are discarded. The rules are rigidly applied. The standards by which science judges its work are universal. There can be no special pleading in the search for the truth: the aim is simply to discover how nature works and to use that information to enhance our intellectual and physical lives. The logic that directs the search is rational and ineluctable at all times and in all circumstances. This quality of science transcends the differences which in other fields of endeavor make one period incommensurate with another, or one cultural expression untranslatable in another context. Science knows no contextual limitations. It merely seeks the truth. Combustion works in every part of the world, in every culture, in every time. The same cannot be said about the "discoveries" of religious revelation.↪Harry Hindu
science is in no way related to religion. They are different methods of seeking truth. One is based on authority and tradition, while the other is based on experiment and observation by your peers.
I know all of that. However, science is now normative, with respect to what ought to be believed, in the way that religion once was. It takes itself as the 'arbiter of reality'. — Wayfarer
To make such claims about science without any examples severely dilutes your argument.Are you seriously suggesting that there is as clear a dichotomy as that? There is no part of science based on authority and tradition? No part of religion based on experiment and observation by peers? I'm sure it is very comforting to live in this black and white world of yours but it is clearly a delusion. — Barry Etheridge
And the point I was making is that some people don't use the word "world" to refer to all there is. Plato distinguished between the world of substance and the world of Forms. The religious distinguish between the world and heaven.
The thing I took issue with was your claim that "If someone claims that the world isn't all there is, I would make the claim that they are misusing terms". You're saying that it's wrong to not use the word "world" to refer to all this is. This assertion needs to be defended. — Michael
To me, the world is all that is — Harry Hindu
Carl Sagan's well-known saying is 'cosmos is all there is, or ever will be'.
I think this type of philosophical naturalism has transposed the Cosmos into the place formerly assigned to God, and assigns science the role previously assigned to religion. Of course that's a lot to say in a short sentence, but there are numerous historical studies which make the case in detail; a notable example being M A Gillespie's The Theological Origins of Modernity. — Wayfarer
People sometimes use the word "world" in a restricted sense. Plato distinguished between the world of substance and the world of the Forms. The religious distinguish the world from heaven (and other afterlives).
To make a case that they're misusing the word "world" you'd first have to justify your claim that what you mean by it is the correct meaning.
And, you know, the word is also used to refer to just the Earth (and everything on it), but I guess we're ignoring that meaning? — Michael
But we do need to ask the question because if other domains have a causal relationship with our domain, then there are effects here in this domain caused by changes in the other domain(s). If there are any causal relationships between domains, then they are all integrated into one whole and it is the whole that science seeks to explain.Thanks, Harry. This word domain can sometimes stand for a subsidiary zone and might be useful to me. I don't claim that the world isn't all there is, myself. I just allege we don't even need to ask and answer that sort of question to get on with our scientific enquiries, our art and our lives. — mcdoodle
To me, the world is all that is - the objective reality, which includes subjective perspectives of it. It is everything. So for someone to say the phrase, "Of the world" I take to mean that some thing is part of the world. This would also imply, to me, that they believe in things NOT of this world. For what would be the purpose of claiming that something is of the world IF the world is all there is because it would be logically deductive that all things are of this world, and therefore redundant to say this.Here's an innocuous phrase I'm suddenly having tremendous difficulty with. 'Of the world'. Why do we use it so much? What are its bounds? — mcdoodle
