This chapter examines how modernity’s will to order produces the categories, norms, and structures through which disabled people are regulated, excluded, and made visible as ‘problems’. Drawing on Bauman’s distinction between solid and liquid modernity, it explores how solid modernity’s gardening culture—animated by productivist visions of work, rationality, and progress—generated classificatory systems that pathologised human difference and constituted impairment as a form of disorder requiring management. These dynamics positioned disabled people as ‘waste’, aligning medicalised accounts of deviance with the regulatory ambitions of the modern state. The chapter argues that eugenic thinking, institutionalisation, and the bureaucratic imagination culminated in the Holocaust, which Bauman understands not as an aberration but as a latent potentiality within modernity’s ordering impulse. It then considers how these structures persist, albeit transformed, in liquid modernity, where older disciplinary logics coexist with new market-driven forms of exclusion. Through this analysis, the chapter shows that the making of the ‘manageable body’ is foundational to solid modernity.
