Ineffable documents an invaluable debate surrounding the use of computational tools in architecture and their effect on human expression. A distinguished group of architects, educators, and theoreticians discuss the potential benefits and the perils associated with the turn to increasing computational complexity in contemporary design culture. Topics considered include: architecture in the posthuman era; the relationship between humans and machines for the future of architecture; and digital phenomenology in architecture. With essays from leading figures Ineffable is for anyone interested in learning more about the political, social, and theoretical implications of the computational revolution in architecture.
