This paper highlights the importance of inter-relationships between language, context, practice and interpretation. These inter-relationships should be of interest to AI researchers working in multi-disciplinary fields such as knowledge based systems, speech and vision. Attention is drawn to the importance of Part II, Section II of Wittgenstein'sPhilosophical Investigations for understanding the enormous complexity of the concept of seeing and how it is woven into an understanding of language and of human relations.
