point one is non logical. You can’t testify to it then you can’t claim it’s true. You can only claim faith or belief in it, you can’t testify to it.

Symbolism provokes a subconscious response that provokes a set of associative emotions. There are approximately zero cases where we cannot convert them to causality. Though, like all qualia, the description of a thing may be unambiguous but it is not the same as fully experiencing a thing. However, qualia is marginally indifferent across humans which is the reason we can communicate once we establish agreement on terms that define the spectrum of experience we refer to.

I am not sure I either understand or agree with your statement on straightness since we are fully aware that physical measurements whether a plumb’s string, a chain’s length, a laser’s distance all measure a world within the limits of marginal indifference for the purpose at hand. The fact that we must compensate for context when discussing ‘lines’ and ‘straight’ is merely degree. In the plumb as the ancients did, it’s context is different from the curvature of earth when measuring landscapes as the medievals did, and is different from the movement of objects in space and time vs the speed of light as moderns do.
