Objectively, is the blue car on the left or the right?
Objectively, is the red car on the left or the right?
Objectively, is the green car on the left or the right?
One might argue that rightness and leftness are objectively physically real but require a 'reference object' or a 'reference place' to be measured. If so, then I say let the 4-sided box be the reference place or reference object, and I ask:
Using the 4-sided box as the reference object, is the blue car on the left or the right?
Using the 4-sided box as the reference object, is the red car on the left or the right?
Using the 4-sided box as the reference object, is the green car on the left or the right?
We can easily create and specify a reference frame that entails left-right (e.g. an x-axis), forward-backward (e.g. a y-axis), or up-and-down (e.g. a z-axis). However, there are infinite ways to do that. The directional orientations such as leftness and rightness would be relative to the made-up created reference frame.
In other words, leftness and rightness are not merely relative in the way that distance is relative.
Directional orientation, such as leftness and rightness, is not merely a relationship between the physical objects in the image. It is relative to a made-up (and therefore transcendental) reference frame; That is, unless we posit consciousnesses (plural) and by extension real conscious presents (plural) that can each act like a reference frame but perhaps be real.
I realize it will be hard to have this discussion without us all getting distracted complimenting me on my incredible graphic design skills, and the unbelievably realistic way in which I can draw stunning images of cars with wonderful details such as beautifully constructed wheels. But, please, my ego can only take so much stroking. The utter amazingness of my drawing goes without saying.
