Mencken, with his acerbic wit and tongue planted permanently near if not in cheek, laments a world where some feel that all original criticism has been done. New ideas are old ideas with new vocabularies. The things we choose to let offend us today are really the same as those in the past wearing shoes with platform souls just to seem a bit more ominous.
With this hopeless situation, it becomes the job of pseudo-scholar to abandon criticism or carnal evils and move on to criticizing the criticism itself. Surely we, being more enlightened, more intelligent and more alive (always a key to proving your superiority to those before your time) can provide a better analysis of what is wrong with everything and right with nothing.
I just dashed this off quickly one evening in an effort to snag others to read and evaluate. Feel free to liberally edit or delete my description.

Since we have been born of immaculate perception, free from the sin of bias, it is our duty to point out for our contemporaries and our posterity what is truly "right" and what is--well, maybe "less right", for in our relativistic culture there is not wrong; 2 + 2 may equal 5 or even 3 from a point of view superior to our own.
Find yourself in these pages. Live life in the third person and begin to recognize how each of us is slave to the history we've studied and lived, servant to our education and personal experience.
