This essay attempts to come to a philosophical understanding of the ethical provocation of speculation as evident in design. I argue that speculative design is a material practice of ethical creative coexistence and present three features of speculative philosophy that manifest in the design and use of two design examples: the Starbuck’s coffee cup and Marti Guixe’s design project, Solar Kitchen Restaurant in La Pin Kulta (2011). The philosophical interpretation relies on object-oriented works of Ian Bogost, Timothy Morton and Jane Bennett and their shared insistence on recognized non-identity.
