I guess there’s the platonist/pythagorean angle that circle, sqaure, and triangle are fundemental forms of seeing and artworks can only approximate them. But even then that is only for the forms of our perception and is not fundemental to the thing in itself, which has neither a name nor a definite shape, but is also in some sense shaped by forces of perception (in a material sense). But then I would argue that technology itself opens up not only new ways of seeing but also new formal possibilities and claiming that there is something fundemental to the forms of seeing to form in general limits those possibilities.
