Reciprocity Whenever human activities incorporate machines or rigidly prescribed procedures, the modes of human interaction change. In general, technical arrangements reduce or eliminate reciprocity. Reciprocity is some manner of interactive give and take, a genuine communication among interacting parties. Ursula M. Franklin, The Real World of Technology reciprocity
The arbitrariness of the sign A key difference between verbal language and the modernist ideal of a visual “language” is the arbitrariness of a verbal sign, which has no natural, inherent relationship to the concept it represents. The sound of the word “horse”, for example, does not innately resemble the concept of a horse. Ferdinand de Saussure called this arbitrariness the fundamental feature of the verbal sign. The meaning of a sign is generated by its relationship to other signs in the language: the sign’s legibility lies in its difference from other signs. Ellen Lupton & J.
