I think this booek is a good book in order to figure out what Eliot think about negativities through Christian doctrine.
Professor Hay searched the whole range of negativity from phiopsophical to christian doetrine.
She started from philoshphical appreaches in negativity to religious approaches. The whole scope of negativity include Eliot's critical doctrine to riligious principle.
this book shows Hay's perspectives about Eliot's spiritual structure ranging from negativity to affirmativity. Changing to affirmativity is achieved through earlier poem to later poetry reaching the still point, the symbol of unification to God.
