Which half? One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?" E.E. Peacock Jr., Seeing With Fresh Eyes science
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.
