Remediation V + Mediation
I would say that this is an extensive description of what may be said with much fewer words. What I am getting from this, is that mediation is an attempt to evoke a response and validate reality by capturing your attention and involving you. (in this sense) Mediation can also be thought of as a way of conveying concepts and realities known or unknown through another perspective.
Remediation is somewhat supplemental or total recreation of the mediation. Perhaps it is in order to create a differential reality to the original mediation.
To tell you the truth, this reading was very wordy and I can only hope that I have in someway been enlightened.
