Hey, DA, if I may pinch your moniker for a mo' –
Trying to get down to the primal point of knowledge is, in my humble opinion, a waste of time.
But following that line of reasoning back and we arrive at the ape who says to the proto-hominid, 'walking on your hind legs is, in my opinion, a waste of time...'
Expanding the horizon is what we humans do. I think it's our defining characteristic.
In every age there are those who have said, 'That's it, this is as far as we're going to get.'
Philosophers from the beginning of time right down to the present give me a headache with their endless finessing of reality until what we end up is that we can know nothing!
That's a really interesting point.
The reason we can know nothing is the knowledge is borrowed, it's not ours, we have not made it our own, and we don't know how to appreciate or value, or even use, what we have ... so in the end we say 'so what?' or 'who cares?' ... It's a particular problem in consumer cultures.
It’s like the famous fable of Medieval scholars debating the number of angels that can dance on the head of a pin.
Or Columbus' sailors thinking they were going to fall off the edge of the world.
Whether or not they actually debated this particular issue is irrelevant.
Of course it's relevant. If they didn't then your next point is irrelevant.
What IS relevant is that there was a fair amount of this type of discussion going on. Specifically endlessly debating topics of no practical value.
A practical joke by college professors is not proof of anything (except maybe they had too much time on their hands?). You've gone from acknowledging a fable to investing it with actuality.
I would say the point is – How do we 'value' a discussion? I have read Stephen Hawking's '
A Brief History of Time' from cover to cover, but could I critically appraise it? No. And what to do with it? I have no idea.
How would we know how to value a discussion between say, Paul Dirac and Erwin Schrödinger?
How many useful scientific breakthroughs emerged from pursuing research for its own sake, research with no immediate 'practical value'?
Such nonsense was hardly limited to Medieval scholars.
But the trick is to discern between what's nonsense and what's not ...
So when does knowledge exist? My response would be ‘Who Cares!’ I believe it is more important to have the wisdom to understand how far knowledge will get you.
This kind of argument stands until what you didn't care about comes to haunt you.
After all, we are trapped into a reality that to our meager senses appears ‘real’. But we know for a fact that our reality is not real.
Only because a philosopher questioned the nature of the real.
The chair I am sitting on is not a solid object. It is composed of a gazillion subatomic particles that bounce around in such a way to create what I perceive is a solid chair.
Ditto.
The wisdom is in the knowledge that even if the chair is not solid, in the reality in which I reside it will always seem solid to me. And that is good enough!
But that's a philosophical position ... do you believe everything everyone tells you?
But it is vital to remember, we can never truly be sure of anything.
Actually you can't say that. It's an absolute ('never') and you're arguing we cannot make absolute statements.
What you can say is, 'I can never be sure of anything' or more accurately, 'there are certain things I am currently not sure of' ... but that is a relative circumstance dependent on contingent factors ... and it applies to you alone, not necessarily everybody.
And to always remember, we ain’t so smart as we think we are!
But we have our moments!
