In Alpha and Omega's preface, Harrison explains why she published such various topics, ranging from magic to post-Impressionism, in one work. She says, "Seen in the fierce glare of war, these theories -- academic in origin and interest -- ... seemed like faded photographs." (v-vi) World War I had brought a melancholy to Harrison's life because pacifist leanings, as admitted in the Epilogue, isolated her.
