Sorry if my answer is not related to your topic, but this video you posted was bit inspirational for thinking in certain view.
If we could agree that today society is in some kind of crisis, so as a system has some malfunction or viruses.Our values are dependent on that system so we constrain our understanding of meaning through our contaminated beliefs.
As immune system fight with viruses with help of vaccines, this how i think society cold fight too.So how vaccines works, you have dead viruses that immune system recognize and then prepare antibody for live viruses.This how you can prevent further disease but how to cure already infected body.
You cant erase deviated values,now you must step out form this previous comparison and try to find out what are the building blocks of this deviated values, because they are viruses.
To find solution for this problem we must understand the source of meaning, because distorted values makes distortion of the core of meaning it self.I think that there must be some kind of meta-meaning, like we could say for notion of god as absolute meta-meaning with some sort of abstract absolute value, even this absolute meta-meaning hes or had through history of society distortion of his meaning.
I toke god as example because is more and less absolute in every human mind, but this is not the case with other meanings of other notions.To find meta-meaning of anything is very difficult in my opinion you must acquire knowledge of etymology , phonology, evolutionary sociology,psychology,and neurology,and even evolutionary biology,and also linguistic, and maybe much more of course history, philosophy, and some computational analysis.
Every meta-meaning is constructed in in and out interaction,between brain and outside world.So meta-meaning contain inside reaction to ongoing reality so if we perceive our self as part of that reality this meat-meaning is objective not subjective agent in forming context meaning which is subjective.And context meanings are forming the meaning of certain notions which are available to us and then we know what is the meaning of words.And maybe the core of memory is this meta-meaning actually.Could be like sufficient input for producing inner to some point pre-programed reaction and all this together,sufficient input and reaction make or are part of meta-meaning.
So first we must find how are this reaction pre-programed.That is why i said first time we must resolve the problem of how is life began.
I would not go further in this my observation in problem of meaning because is to long and i am not have enough knowledge, just trying to share some thoughts maybe they are not just bunch of bullshit.And sorry for my bad english.
