I appreciate the thoroughness of your thinking.
We are along the same lines in our perception.
I also do not think that we can understand subjectivity objectively.
However, unfortunately there may be cross interference in terms.
Perhaps the term "know" rather than "understand" may fit better since subjectivity is something that must be "experienced" first hand to truly "know" what it is whereas objective bits of information/interpretation can be passed along through any outside means...paper, television, internet, ect.
I guess it can be akin to reading and studying as much theory as you want on swimming objectively...but until you actually jump in a pool...feel me?
Here is the video I originally meant to post...
