Gabriel Tarde and cultural evolution: The consequence of neglecting our Mendel

After documenting Tarde’s neglect and placing him in the 19th-century sociological context, this paper argues that his concept of “imitation” was important because social learning (writ small) or culture (writ large), a non-genetic form of heredity, means that a distinct cultural evolutionary process including variation and selection resulting in descent with modification is inevitable. Beginning in the last half of the 20th century there was a flowering of theorizing and research about cultural evolution across the humanities and social sciences and eventually about culture in general in sociology. Unfortunately, what should have been recognized as Tarde’s role as a forefather of these has only occasionally been recognized.
