Are there foundations to rest upon? We’re all affected by gravity so there’s that.
What about metaphorical foundations?
So, to start, we are immediately transported into the realm of abstraction. It is removed from reality by at least one level: the level of a physical foundation to now a metaphorical foundation.
So, using a metaphorical foundation as a footing, what can we build with in that realm?
Concepts, usually expressed as sentences and sometimes using just words for shortcuts to their definitions.
So, let’s use short cut metaphorical building materials. Single words.
1520s, “oblique or diagonal line,” from French biais “a slant, a slope, an oblique,”
So, a slant.
It is not perfectly vertical nor is it perfectly horizontal but it is at an angle.
One can think of a vertical and horizontal line as ALSO being a bias but I think it’s possible to temporarily leave the vertical and horizontal positions alone and focus on a slant.
So it’s probably from the Latin “(e)bigassius from Greek epikarsios “athwart, crosswise, at an angle,” from epi “upon” (see epi-) + karsios “oblique” (from PIE *krs-yo-, suffixed form of root *sker- (1) “to cut”).”
Already I’m showing a bias.
I’m baised towards etymology as a foundation.
I’m biased towards considering a physical foundation as primary with the abstraction of the physical as emergent properties.
But does a bias invalidate a position? I don’t know. But an honest acknowledge of baises-in-use allows for honest and transparent communication.
We are often obscure to ourselves, not even being cognizant.
