Further to yesterday's post on Gary Taylor's introduction to the Oxford Henry V, one of his most compelling arguments (which happens to fit into my theory regarding this play being Shakespeare's epic) is the description by which he shows the large-scale organization of the work. I'll give you the quote in full, which I believe is accurate, but it is from my notes, so I apologize in advance for any discrepancy. Taylor writes that the play "advances dialectically: no sooner is a unity established than we are made aware of what that unity excludes, until that too can be contained. After the divisions of the first two scenes, Henry and his court are by the end of act one united in their common purpose - and immediately we are shown Eastcheap brawling. After Southampton, Henry can leave behind an undivided England - and we are reminded, through Falstaff, and those who have loved him, of an entire world Henry has excluded. So the process continues until, after the achievement of Agincourt, in the consummation of the dialect, Burgundy insists that the harmony must include France as well as England."
My contention is that Shakespeare was writing an epic not only for the people of England, but for all people who want to live in a civilized and just manner. He used the very symbol of patriotism and empire-building to subvert those ideals, and to show us a way of thinking that we must aspire to if we are to have a peaceful future. The play shows us that differences of opinion (as are written into the role of the protagonist and the fact that he is shown having to accept views opposed to his own, even those of common soldiers such as Williams) are not a nuisance, they are a necessity. Only in tyrannies are opposing views silenced, and only in tyrannies is no thought given to the effects our actions might have on those not, at first glance, on our side.
