Novels aren't pedagogical instruments, or instructions in law or physics or any other discipline. A novel has to be an emotional experience, a trip of the imagination, and because science has raised so many issues that concern and affect humans, it's a good starting place for me.
The book is finished by the reader. A good novel should invite the reader in and let the reader participate in the creative experience and bring their own life experiences to it, interpret with their own individual life experiences. Every reader gets something different from a book and every reader, in a sense, completes it in a different way.
I have for a long time loved fabulist, imaginative fiction, such as the writing of Italo Calvino, Jose Saramago, Michael Bulgakov, and Salman Rushdie. I also like the magic realist writers, such as Borges and Marquez, and feel that interesting truths can be learned about our world by exploring highly distorted worlds.
I picked such seemingly disparate essays, I thought it was important to say what was the guiding principle in the selection rather than focus on any one essay. I reached for some principle that had been subconscious in me and lifted it into consciousness. Authenticity and sincerity were the most important unifying principles of all these apparently different essays.
