This article provides the first detailed modern examination of Julia Wedgwood’s interventions in the Victorian debate about the origin of language. Wedgwood wanted to understand language, consistently with Darwin’s theory of evolution, as having evolved gradually out of other forms of animal behaviour. She focused specifically on imitative behaviours, siding with the imitative or “bow-wow” theory of language which her father Hensleigh Wedgwood also championed. She opposed the conceptualist or “ding-dong” theory of Max Müller, on which language is the “Rubicon” that radically separates humans from animals. I argue that Julia Wedgwood was right to emphasise that the human capacity for language is continuous with animal behaviours, though she was wrong to reduce this continuity to a single behaviour, imitation. Nevertheless, her language essays remain significant as an early attempt to forge a Darwinian account of language, and they illuminate the fact that women were able to take part in Victorian philosophical debates, including on an abstract topic such as philosophy of language. The essays also provide entry into Wedgwood’s thought and work more broadly, which are unjustly neglected and deserve to be recovered.
