The seventeenth and early eighteenth centuries saw the emergence of sensationalism as a counter to the prevailing idea that human knowledge was innate, pre-determined within us, only to emerge gradually over time. This chapter considers the influence of the theory of sensationalism on both the conceptualization of intellectual disability and the emergence of educational efforts on their behalf. It considers how the debate over sensationalism shaped Itard’s work and the theories which underpinned it, rooted most fully in the work of Locke, Rousseau, and, finally, Condillac, whose revision of Locke would create the foundation for the coming medico-psychological hegemony over intellectual disability.
This collection explores how concepts of intellectual or learning disability evolved from a range of influences, gradually developing from earlier and decidedly distinct concepts, including ‘idiocy’ and ‘folly’, which were themselves generated by very specific social and intellectual environments. With essays extending across legal, educational, literary, religious, philosophical, and psychiatric histories, this collection maintains a rigorous distinction between historical and contemporary concepts in demonstrating how intellectual disability and related notions were products of the prevailing social, cultural, and intellectual environments in which they took form, and themselves performed important functions within these environments. Focusing on British and European material from the middle ages to the late nineteenth century, this collection asks ‘How and why did these concepts form?’ ‘How did they connect with one another?’ and ‘What historical circumstances contributed to building these connections?’ While the emphasis is on conceptual history or a history of ideas, these essays also address the consequences of these defining forces for the people who found themselves enclosed by the shifting definitional field.
The emergent critical history of intellectual disability
Patrick McDonagh, C.F. Goodey, and Tim Stainton
Intellectual disability is an unstable concept, and its fundamental instability is magnified when we track its history and relation to other concepts. This introductory chapter explores some of the challenges of investigating the forces shaping the concept of intellectual disability in Europe and Britain across the centuries: not only those generated by shifting language and terminology, but also the demands imposed by the interdisciplinary nature of this project, which takes us through histories of literature, religion, law, education, philosophy, psychology and medicine, in addition to engaging with cultural and social history. Further, the fundamental slipperiness of the idea of intellectual disability raises the question of whether it could even be said to exist in forms similar to that which it assumes today. This introduction also includes a review of literature exploring the history of intellectual disability, and an overview of the chapters to follow.
