Signal Fires is a novel concerned with the nature of time. Dani Shapiro explores philosophies of metaphysics in order to propose the idea that time is nonlinear, and that people are interconnected through time and space. The term metaphysics is derived from the Greek “meta ta physika,” which means “after the things of nature.” Metaphysics is therefore a study of what can’t be studied through the analysis of material objects. It proposes that there is an essence to everything, but this essence is not necessarily definable or witnessable. The three major categories of metaphysics are general metaphysics, physical metaphysics, and religious metaphysics.
Physical metaphysics is concerned with the structures and origins of the universe. Waldo is interested in physical metaphysics as demonstrated by his knowledge of the stars and universe. When Waldo compares a dying star’s matter being reincarnated into other celestial objects to a human dying but living on in spirit, he is engaging in physical metaphysics. He doesn’t know how or why these things happen; he just knows that they do happen.
Religious metaphysics is concerned with how and why religious ideology came to be, and how it continues to structure society. Metaphysics is therefore one of the few academic disciplines that treats science and religion as equally important; a scientist can’t necessarily explain the formation of the universe just as a practitioner of Christianity can’t necessarily explain how and why Jesus walked on water. Shapiro pays homage to religious metaphysics through Mimi’s use of Jewish prayers during times of need.
One major question in metaphysics is the use of language itself: Our perception of the meaning of the universe is dependent on the language we use. Waldo and Benjamin connect over a similar use of language, whereas Waldo and his father Shenkman are divided in their use of language. Thus, it is not just understanding metaphysics that influences how characters relate to one another, but the ways in which the characters conceptualize or verbalize the meaning of life.
The family drama is a literary genre that explores the way families deal with conflict. Family dramas often explore the dynamics of power within a family unit, placing certain characters in different roles of influence and power. They are popular because they are relatable, accessible, and often explore universal themes of what it’s like to be within a microcosm of society.
Louisa May Alcott’s 1868 classic Little Women is a formative family drama that popularized the genre. In Little Women, the four March sisters deal with conflicts of poverty, an absent father, and their own hopes and dreams. When the girls are forced to grow up and find their paths in life, the divergence of their sisterhood challenges their identities. Mario Puzo’s 1969 novel The Godfather is another, though different, example of the family drama. In The Godfather, conflicts involve business dealings, loyalty, and survival. The central family is part of the mafia, and the characters’ developments are based on conforming to certain rules.
The contemporary literary landscape has seen an upsurge in family drama novels. This is Where I Leave You by Jonathan Tropper (published in 2003), My Sister’s Keeper by Jodi Picoult (2004), Everything I Never Told You by Celeste Ng (2014), Commonwealth by Ann Patchett (2016), The Nest by Cynthia D’Aprix Sweeney (2016), and Pachinko by Min Jin Lee (2017) are all best-selling novels that deal with familial relationships and how these dynamics influence individual growth.
Signal Fires by Dani Shapiro is a family drama because its conflicts involve two families—the Wilfs and the Shenkmans. Through the novel’s structure, in which every character gets their own chapters, Shapiro outlines how larger family conflicts can influence the wellbeing of individual family members. The novel begins with a family secret: the death of Sarah and Theo Wilf’s friend, Misty, and the siblings’ part in it. Sarah’s lie regarding her part in the death (as Theo was the driver in the car accident that killed Misty), a way to protect her brother, keeps the siblings connected and prevents them from receiving the help they need. This conflict haunts Sarah and Theo, and they struggle with self-harm as the years go on. Their parents, Ben and Mimi, are helpless in preventing their children’s self-destruction because they are also bound by the secret, unable to speak about it. However, the Wilfs eventually comes together after the disappearance and death of Mimi Shenkman.
The Shenkmans also experience their own drama. Waldo is misunderstood by his parents, especially his father Shenkman, who suffers from his own resentment. Shenkman loves Waldo but expresses his concern for Waldo’s perceived differences through anger and punishment. The schism in their family is based on a lack of openness and acceptance. Waldo is forever scarred by his father’s treatment of him, despite Shenkman softening over the years. When Waldo’s mother Alice dies, he feels the distance between him and his father grow. Shenkman ends up alone, while Waldo develops a friendship with Ben and eventually starts a family of his own.
The Wilfs and the Shenkmans share a conflict when Mimi runs away from her nursing home and Waldo runs away from home. Mimi and Waldo find each other, and Waldo helps comfort Mimi as she dies. Years ago, Ben helped Alice give birth to Waldo in her kitchen. There has always been an invisible bond between the Wilfs and the Shenkmans, and their close proximity to each other’s conflicts shows that all families go through problems.
