talk2farley,
This is where you and I seem to differ. That things were and will be is not subject to agreemnt. Does the sun take a moment to consider our shared expectations that it will rise tomorrow morning? What *is* subject to "agreement" (though I would call it observed, rather than popular, agreement) is our *understanding* of what was and will be.
Yes, good point for clarification: it is about our *understanding* of what was, is or will be. And this understanding is a matter of agreement, in the end -- don't you think?
I'll get back to this later in the post.
Its the "web of belief," (Quine, was it?) something you seem to reference extensively.
Yes, thank you for reminding me of Quine.

I need to brush up my knowledge on his theories. Man, that man is the master of spinning stuff 'round and 'round. But I do agree with him, mostly.
"Well, what we think that reality is, is a matter of our perceptions, isn't it?"
Yes, I agree. They keyword, however, is *think.* What we think reality is, is not necesarrily so!
Exactly! This is what I am building on. And this is why I integrated that premise of social agreement about the understanding of things.
I always like to stress: We don't *know* or *understand* the world and ourselves in the strict sense of the words "know" and "understand". We are only acquainted with the world and ourselves, and we are able to live with them.
By definition, there can be only one reality. Also by definition, it is perception, a seperate animal entirely, which is both subjective and individual. We must cautiously differentiate the two.
You see, this is where it gets all tangled up into social agreements.
That we use Occham's Rasor as a tool, is a social agreement in our society. For example, the way we conceive the movement of the planets is based on Occham's Rasor.
There are other ways to explain the movements of the planets, which would give the exact same picture we get to see from Earth. But, Occham's Rasor is implemented and this is why the Universe is to us what it is ... for now.
And if this society had never existed, would the time it took the earth to revolve completely along its own axis change?
If this society had never existed -- the things would be whatever they are ...
And even if there is a society, the things are still what they are -- but different societies *understand* them differently.
Take calenders, for example: not all have a year of 365 (...!!) days.
Again, yes, fact and truth, as used in science, are subject to change. However, this has little to do with popular will nor common sense. Common sense is NOT a scientific process, which, coincidentally, is why it so often is wrong.
When I use "social agreement" I am *not* referring to "common sense" alone.
Examples of social agreements -- in the widest sense:
"We use Occham's Rasor."
"Science makes new findings, and we incorporate these new findings into our belief structure."
"Formal logics are the principles by which we construct and understand arguments."
...
Note that in a, say, Christian cosmogony and the society that lives by it, the statement "Formal logics are the principles by which we construct and understand arguments." is not a socially accepted premise!
Who are we to say that the Christian cosmogony is wrong? Or right?
It *works* for Christians, and this is what makes is viable and socially obligatory in a Christian society.
I wanted to be as unbiased as possible with my theory, this is why I didn't specify official science as THE measure of our understanding of things.
In a society where science is regarded as the ultimately obligatory approach to truly (" ") understand reality, science has the upper hand in saying what is or is not.
In a society where a certain religion is regarded as the ultimately obligatory approach to truly (" ") understand reality, this very religion has the upper hand in saying what is or is not.
Of course, in today's western world, things are a tad more complicated ... and mixed up.
