Until man had the means (the science) to actually see the Earth from space the shape of the Earth was just as abstract!
I thought you were arguing about "objective things." The shape of the earth has not changed. People's notions about the shape of the earth has changed. Let me restate my original statement. The earth is a physical entity. Justice is a concept. You can't touch justice, you can't eat justice, you can't live in justice, you can't drive justice, you can't hold justice. Justice exists only in the mind. Therefore, it is abstract.
Everything in your mind starts out as a concept!
Why can't you understand that?
Learning the difference between the impact of false conceptual premises and true conceptual premises is the subject of our discussion!
Do you not see the hypocritcal nature of your argument now?
Religion, the Bible, Christianity can throw metaphors around like crazy and you embrace it with warm hugs and a teary eye like it was a hot meal on a cold night. But, when it comes to having a discussion about conceptual matters you get all indignant when definitions are called for and it becomes necessary to parse practical from impractical consequences.
The shape of the earth is only a PHYSICAL matter because we have CONCEPTUALIZED it as such.
Otherwise, it would be like Camelot or Atlantis.
Further, there was historically an honest debate about the matter of Earth's flatness vs roundness fueled by the fact IT WASN'T POSSIBLE YET to view Earth from a vantage point.
Now it is no longer INTELLECTUALLY HONEST to claim the Earth is flat. Why? Because we can provide substantiating evidence which trumps the old arguments about antipodes, etc.
The same is true of BIBLE EXPLANATIONS.
Surely you see this.
