What is Slaughterhouse-Five about?

Slaughterhouse-Five (1969) follows Billy Pilgrim, who is "unstuck in time" — he experiences his life non-linearly, jumping between his childhood, his time as a POW in Dresden during the Allied firebombing, and his life afterward, including an alien abduction by Tralfamadorians. The novel is also Vonnegut's fictionalized memoir of surviving the Dresden firebombing (February 1945), in which approximately 25,000 people died.

What is the Tralfamadorian philosophy?

The Tralfamadorians experience all moments simultaneously and don't have the concept of free will — everything is fixed and has always been fixed. They find Billy's distress about death incomprehensible: the person is dead in that moment but alive in others. Their famous response to any tragedy: "So it goes."

What is Vonnegut saying about war through the Tralfamadorian philosophy?

It's ambiguous — and deliberately so. The Tralfamadorian philosophy can read as: (a) a coping mechanism — the only way to survive overwhelming trauma is to adopt a worldview that treats it as inevitable; or (b) a critique — this is exactly how the institutions that conduct wars think about civilian deaths. "So it goes." The two readings coexist.

What is the novel's central anti-war argument?

Not an argument, really — Vonnegut said you can't argue against war. War is too exciting, too lucrative, too intertwined with human identity. Instead: he makes war look absurd, specifically through the Dresden firebombing, which killed far more people than Hiroshima and is far less remembered. The obscurity of the atrocity is the point.

Why does the novel remain essential?

Because it refuses to explain its trauma. It shows what happens to a person who survives something that shouldn't be survivable, through the only form available — non-linear, absurdist, unable to proceed straight through the memory. The form is the content.
