In epistemology, Sensualism is a doctrine whereby sensations and perception are the basic and most important form of true cognition.[citation needed] It may oppose abstract ideas.[1]

This ideogenetic[clarification needed] question was long ago put forward in Greek philosophy (Stoicism, Epicureanism) and further developed to the full by the British Sensualists (John Locke, David Hume) and the British Associationists (Thomas Brown, David Hartley, Joseph Priestley). In the 19th century it was very much taken up by the Positivists (Auguste Comte, Herbert Spencer, Hippolyte Taine, Émile Littré)[2][3]

See The World as Will and Representation, Volume II, Chapter VII. It is possible that it was mentioned by the Stoic Cicero and was repeated by Augustine of Hippo and Thomas Aquinas.
