"To me, In Memorium is an odyssey in the working out of extended grief. I am awestruck all the more because Tennyson composed the verses in haphazard fashion over seventeen years, yet the sequence of 131 sections rings so true of a chronological account of grieving. How could Tennyson remember and capture the sequence so beautifully? How could he integrate the swirling and swinging moods: the anger, the despair, the emptiness, the search for answers, the exultation of temporary resolution... Above all, I admire Tennyson's treatment of the relationship between science and human values... As a champion of science, Tennyson lauds its power... but he knows that science cannot tell us why a man should die so young, or how a grieving lover should resolve his suffering."
