Is it true that what 'was' still 'is'?

Throughout Go Down Moses, we have examined the interconnectedness of past and present and made the conclusion that what 'was' in the past still 'is' in the later short stories which follow the so called 'future' generations of Buck, Buddy and Old Carothers. However, in Delta Autumn, the significant differences and changes between the 'old' and 'new' South seem most apparent. There is a blatant division between Uncle Isaac and McCaslin who revere the wilderness and the land and the new generation, which seems to disregard it. This becomes obvious at the end of Delta Autumn when he says "It was a doe"(347). The fact that Roth shoots the doe shows that he has forgotten Sam Father's lessons of old that there is a time "not only when to shoot but when not to" (333). These new generations have further forgotten and abandoned God as is obvious when the old man says that "the only fighting anywhere that ever had anything of God's belling on it has been when men fought to protect does and fawns" (323), and the past values and traditions have been cast aside. Additionally, throughout the previous stories and particularly in The Bear, industrialism is encroaching on the wilderness, which is representative of the past and its traditions. In Delta Autumn Uncle Ike reflects that there is "no scream of panther but instead the long hooting of locomotives" (324). The comparison of the natural world to industrial objects shows the progression of the South towards this brave new world that is not compatible with the old values of nature. This progression suggests that what 'was' no longer 'is'. The past is only resurrected in old Uncle Ike's of "the old men...moving again among the shades of tall unaxed trees and sightless brakes where the wild strong immortal game ran forever before the tireless belling immortal hounds, falling and rising phoenix like to the soundless guns" (337). Although the image of the pheonix suggests a cyclical nature of change and suggests that the old hunt may one day be resurrected, it also shows that right now that old way of the hunt is lost in reality even if it is perserved in memory. I challenge that what 'was' 'is' in Go Down, Moses, and instead think that Delta Autumn is Faulkner's way of saying that the past has been cleared away for the new south. What do you think?
