The spectrum of semantic and syntactic labour

Purpose. The article extends the distinction of semantic from syntactic labour to comprehend all forms of mental labour. It answers a critique from de Fremery and Buckland (2022), which required envisaging mental labour as a differentiated spectrum.
Design/methodology/approach. The paper adopts a discursive approach. It first reviews the significance and extensive diffusion of the distinction of semantic from syntactic labour. Second, it integrates semantic and syntactic labour along a vertical dimension within mental labour, indicating analogies in principle with, and differences in application from, the inherited distinction of intellectual from clerical labour. Third, it develops semantic labour to the very highest level, on a consistent principle of differentiation from syntactic labour. Finally, it reintegrates the understanding developed of semantic labour with syntactic labour, confirming that they can fully and informatively occupy mental labour
Findings. The article further validates the distinction of semantic from syntactic labour. It enables us to address Norbert Wiener’s classic challenge of appropriately distributing activity between human and computer.
Originality. The paper is highly original. Although based on preceding research, from the late 20th century, it is the first separately published full account of semantic and syntactic labour.
