Pulford: Scientists who study the remains of ancient historical figures to learn about their health history need to first ask themselves if their investigation is a legitimate scientific inquiry or is motivated by mere curiosity. An investigation into a private matter such as health history is justified only if it is done for the advancement of scientific knowledge. Varela: You forget that curiosity is the root of scientific inquiry. Many great scientific discoveries were motivated by curiosity alone. Varela responds to Pulford's argument by ['attempting to draw a distinction between two views that Pulford treats as a single view', 'disputing the validity of a principle that Pulford explicitly states', "maintaining that Pulford's argument is based on inconsistent premises", "contending that Pulford's argument rests on an untenable distinction"]
