Callinicus: A Defence of Chemical Warfare

One of the most intellectually provocative and morally uncomfortable books ever written by a serious scientist. J.B.S. Haldane, whoblinded himself in one eye fighting in the trenches of World War I, offers a coldly logical defence of chemical warfare that challenges everything we think we know about weapons and civilization. The argument is ruthless in its consistency: if war must happen, might gas not be more humane than bayonets, shrapnel, and the gangrene that killed so many in field hospitals? Named for the 7th-century Syrian who allegedly invented Greek fire, Callinicus is not a promotion of cruelty but a brutal thought experiment in utilitarian ethics. Haldane asks readers to do the mathematics of suffering and find themself unnerved by the answers. A document of immense historical importance and continuing relevance, this short, polemical work forces us to confront how moral intuitions and strategic realities often collide.
