According to Hume, idea of self doesn't exist. What did Berkeley say about SELF?Then who is watching you when you are asleep. Does that mean you don't exist when you are asleep. — Abhiram
??have existence in this physical world but all encompassing physical reality , space, time and thought with it. Like an intertwined whole with several distinguishable parts which cannot be separated — Abhiram
Agreed. Human consciousness applies math to all the objects in the universe, but some folks think that math is embedded in the universe.And, to tie it back to the OP, math is one of those things, restricted to human Consciousness and, therefore, only "real" insofar as constructed and perceived. — ENOAH
Is Modern Greek a lot different from Ancient Greek? It would be advantageous to know Ancient Greek for reading philosophy.I wish people into scholastic philosophy and theology were obliged to study Modern Greek so they realise how silly they sound, and how the usage of foreign words does not grant them mystique. — Lionino
Are there anything more than matter and motion in the universe?In the logic thread I proposed "logos" for the logic-like function of the world. I wonder what a good term would be for "the apparently mathematical in nature?" Quantos? Mathematicularity? Máthēma? Quanticularity? — Count Timothy von Icarus
No. They're not that fancy. They're practicing math scholars and philosophers. — L'éléphant
The closest ancient Greek word for truth is "aletheia", which can be analysed etymologically a (negation) + lethe (concealment, forgetfulness, escape) = aletheia.
It doesn't quite reflect a word for truth, does it? — Corvus
Truly can mean truthfully and rightly too. Truth is an English word for truth. :DTruly in English means "really" all the time, does that mean English has no word for truth? — Lionino
He says due to the fact it is difficult to translate "aletheia" into the English word "truth" — Corvus
He also points out the word "aletheia" had been used by Heidegger to describe the character of the world. — Corvus
I think his point is that aletheia in ancient Greek meaning is different from modern day meaning of truth.Despite not having read the article, I don't think Jan Szaif's point is that Greek had no word for truth. — Lionino
Do you believe in eternal resurrection? That would be a Nietzschean idea, wouldn't it?500 years from now I will come back from the dead and use the word "Heidegger" to describe break-dancing at a beach. Hopefully the academics will talk about that in 600 years. — Lionino
It is called existential experience. You know you exist ?right? It is simply the experience of your existence. You are experiencing it you can't deny it. It is simply that experience. If you are not aware of it then I suppose you might have to wait for an existential crisis to happen. Then you will be aware of your existence. — Abhiram
physical reality , space, time and thought with it. Like an intertwined whole with several distinguishable parts which cannot be separated — Abhiram
It is also difficult to translate "truly" into the Greek word "alithinos", for the reason I brought up above. It is also difficult to translate "demokratia" into the English word "democracy". Despite not having read the article, I don't think Jan Szaif's point is that Greek had no word for truth. — Lionino
Truth in ancient Greek meant concrete existence opposed to mere appearance or beliefs — Corvus
They had no idea of verified truth from observation and experiment. — Corvus
it wasn't identical meaning to today's concept of truth. — Corvus
Unhidden and unconcealment was the Etymology, and concrete existence opposed to mere appearance or beliefs is Epistemology.First you said it means unconcealed, now this. Which one is it? — Lionino
Today's concept of truth is vastly broader with the modal logic, fuzzi logic and dynamic, epistemic logic ... etc etc and Science has many different concept of truth too.What today's concept of truth? — Lionino
The sky is blue is not always true. The sky is black at nights, and grey in cloudy days. The sky is green is true if you wore a green sunglass and look at the sky. Hence, the sky is blue is only true when the sky is blue. The sky is green is true when you wear a green colour lensed sunglasses and look at the sky, or through the green glass of the window.Greeks knew that "the sky is blue" is true and "the sky is green" is false. — Lionino
That sentence is false.That "true" does not match "alithís" is a mootpoint, — Lionino
Greeks did not have theories of truth like we have today, but many philosophers back then talked about what truth is. How can they not have a concept of truth? — Lionino
they agreed to something, they feel something is right, or they have unconcealed something from the hidden. — Corvus
These seem like concepts of truth to me. Maybe they hadn't developed certain vocabularies about truth that modern philosophy has, but... if they agree with one statement about the world and disagree with another one, does that not imply at least a most basic concept of truth? — flannel jesus
I am not, but I know many Greeks. I think they would stand by that there is nothing different between Greek's and English's 'true', etymology nonwithstanding. — Lionino
Another QM interpretation holds that the quantum field is a Hilbert space, not just mathematically but actually, which would make the physical world part of the set-theory universe, reversing the question this thread raises. I personally find this non-appealing for a few reasons. — Gary Venter
Quantum field theory (QFT) is a theoretical framework that combines quantum mechanics and special relativity to describe the behavior of elementary particles and their interactions. In the context of QFT, the quantum fields themselves are typically described mathematically as operator-valued fields defined on spacetime.
A Hilbert space is a mathematical concept used to describe the state space of a quantum system, where states are represented by vectors and physical observables are represented by operators. In quantum mechanics, the state space of a single particle is often described by a Hilbert space.
In quantum field theory, the state space becomes more complex due to the infinite degrees of freedom associated with fields defined at every point in spacetime. The state space of a quantum field theory is typically described by a Fock space, which is a direct sum of tensor products of Hilbert spaces associated with different numbers of particles. Each mode of the field (corresponding to a particular momentum) can be thought of as a harmonic oscillator, with its own associated Hilbert space.
So, while individual components of a quantum field theory can be described by Hilbert spaces, the full quantum field itself is typically not described by a single Hilbert space, but rather by a more complex structure known as a Fock space.
