Are ideas immortal?

Will certain concepts in general, ones that do not depend on the physical world to exist, continue to exist forever? Will they continue to exist with the absence of the physical world or not?
Could it not be thought up in the imagination, thus existing within the conceptual mind? Or does existence purely rely on the relationship between the physical and mental worlds?

The basis of the question is an assumption that an idea can exist. So then what are the characteristics of existence?

I guess some ideas are immortal, that is if you mean within the particular species of the person/thing that had that idea. However, when that species dies then so does that idea, or most likely.

Even after every mind on earth was silenced, there would still be evidence left behind. But then this makes the assumption that the existence of a concept is contingent on someone to be aware of it.

Well, some ideas will probably blindly repeat themselves even to other species that may inhabit this planet in the future or another planet.

and as BF says... other planets...
I can guess that there will be aliens there that want it too

ideas exist as long as there is creatures that can think about them

I don't think so. I don't think an idea is an independent unit. It's the product of someone's mind, someone who's been moved and inspired by the surroundings (even lack of these, but even a lack indicates that something has existed/exists elsewhere).
Some ideas, like Yerssot's power-idea, might simply come down to genes, survival of the fittest and such.
It's been proven that some fairy tales are the same no matter what country we're in, that some tales are known by everybody, but I do think it has more to do with our physics, genes and drives, than actual immortal, independent ideas.

wow Storm thats alot of mind aching questions there 😉.

Ok first of all will ideas which don’t depend on the physical world to exist, continue to exist for forever?
Can they continue to exist with the absence of the physical world?
To tell the truth I don’t really fully understand the question but would the concept of mathematics continue to exist if there is nothing to apply it to. Would a can of Pepsi exist if there was no such thing as Pepsi? Could it not be thought up in our minds and imaginations, thus existing within our conceptual mind? Or does existence rely on the relationships between physical and imaginative worlds?
I believe some concepts are immortal and some are not.

Gosh that’s brought up more questions then answers then question, but that philosophy. 🙂

If the physical world ceases to exist, so will any ideas that were brought about by it. Imagination is a thing created by life, and so needs life to prolong its existence.

All ideas are immortal ... all that you have thought have has been done... or will be done ... unless it has to do with new technology... ever heard of history repeating itself... its not history... its ideals.

And so thousands of years after Homo sapiens got self-aware, we’re still trying to figure out how it works – the mind 😄
Well, an idea can be in one persons mind or in the minds of several people. Since thoughts are electro-chemical signals the idea/thought needs a living vessel to survive, one capable of thinking the idea.
So – if there are no one alive to think the thought or the idea, the thought/idea ceases to exist.
If the idea/thought is written down/stored of course it can technically survive as long as the storage unit (paper, disk, HD what have you). But I wouldn’t say the idea was really surviving…
You need a mind to contemplate the CONTENT of the idea. My computer still refuses to KNOW what I mean, if I make a typo in google for example 😄

Yeah, absolutely agree with Omega. ✅👆

There needs to be someone to think the idea, it cant just exist...by itself.

They're immortal as the person who thought of them.

yup..the two are linked...u can't have ideas last forever without someone/something to "store" that idea "in"... if all physical evidence whatsoever of human presence on earth were to be wiped out, and another race come to inhabit this place, they would have no way of knowing our ideas...they wouldn't even know we existed...

Doesn't that concept link in somehow with the idea that when a tree is felled in a forest it only makes a sound if there is someone to hear it?

No. The idea that if the tree falls in the forest and there is no one there to hear it, does it make a sound, of course it does. Sound has properties, its created by waves reguardless of whethere there is someone there to hear it or not.

Ideas, someone has to think of for them to exist. Ideas, have no physical properties of any kind.

Yeah, I know that Milla, my answer would have been the same as yours, but I was just trying to say that if there has to be someone to think the idea in order for it to exist, surely there would have to be someone to hear the sound, for it to exist. I'm just trying to look at it from another perspective, and surely ideas have properties also?

Ideas are a mental concept, not physical. But, of course, sound is a physical concept, not mental.

Exactly. Thats why if a tree does fall in a forest, and here is no one there, it will make a sound, but if someone with the idea dies, the idea will die with them. 👆

OK, make me feel dumb, cheers 😛

I get that, I was just trying to introduce another perspective ✅
