This special issue of Mind, Culture, and Activity revisits Rommetveit's ideas in admiration for his quest to understand meaning, language, and mind. It also reflects the inspiration he has provided for those struggling with these issues. Written by those studying Rommetveit and one by Rommetveit himself, all three articles are attempts to spell out, extend, and apply ideas that Rommetveit outlined in his writings at some point early in his career. Rommetveit, however has moved ahead in his struggle to understand the ethical dimensions of communication--including the communication involved in the study of communication--which represents his newest project.
