%0 Journal Article %T Making liberal use of Kant? Democratic peace theory and Perpetual Peace %A Sid Simpson %J International Relations %@ 1741-2862 %D 2019 %R 10.1177/0047117818811463 %X The work of Immanuel Kant has been foundational in modern democratic peace theory. His essay Toward Perpetual Peace gives three prescriptions for attaining peace between democracies: republican institutions, a pacific union between states, and an ethos of universal hospitality. Contemporary democratic peace theory, however, has warped the Kantian framework from which it draws inspiration: the third prescription has been gradually substituted for commerce and trade. I argue that this change in emphasis produces tensions between Perpetual Peace and the body of democratic peace theory literature it spawned. Moreover, I contend that a look back at Kant¡¯s essay sheds light on why this transformation occurred. Finally, I use this new look back at Perpetual Peace to reformulate the relationship between peace, democracy, and commerce so as to offer a new perspective on the democratic peace theory/capitalist peace theory debate %K commerce %K democracy %K democratic peace theory %K Kant %K peace %K trade %U https://journals.sagepub.com/doi/full/10.1177/0047117818811463
