Scottish Enlightenment : An eighteenth-century intellectual movement centered in Scotland, known for work in philosophy, science, political economy, and history. Stewart’s teaching and writings extended this movement’s intellectual influence into the nineteenth century.
Elements of the Philosophy of the Human Mind : Dugald Stewart’s major work on perception, memory, imagination, reasoning, and other powers of the human mind. This work sets out his systematic account of mental faculties and their operations.
Francis Hutcheson : An Irish-born philosopher whose moral-sense theory influenced Scottish moral philosophy and the Scottish Enlightenment. Hutcheson helped establish the moral-philosophy tradition in which Stewart later taught.
Scottish common sense realism : A Scottish philosophical tradition that argues ordinary perception provides direct, generally trustworthy knowledge of the external world. Stewart helped transmit and elaborate this tradition after Thomas Reid.
Thomas Reid : A Scottish philosopher who founded the school of common-sense philosophy and challenged skeptical theories of perception. Stewart developed Reid’s defense of common sense into a broader account of the human faculties.
Perception : The process by which sensory information is organized into representations of objects and events. Stewart treated perception as a basic source of knowledge that skeptical arguments could not eliminate.
Adam Ferguson : A Scottish philosopher and historian known for his analysis of civil society and social development. Ferguson preceded Stewart in Edinburgh’s moral-philosophy chair and belonged to the same intellectual circle.
British idealism : A nineteenth- and early twentieth-century British movement that treated reality as fundamentally spiritual or mind-dependent. Its later prominence contrasts with the common-sense realism Stewart helped sustain.
Common-sense philosophy : A philosophical tradition that treats certain ordinary beliefs and judgments as foundational and resistant to skeptical doubt. Its principles shaped Stewart’s approach to perception, reasoning, and moral judgment.
Association of ideas : The process by which one idea tends to call another to mind through learned or natural connections. Stewart used association to explain how thoughts connect without reducing every mental operation to it.
