They argued because they liked argument, liked the swift run of the unfettered mind along the paths of possibility, liked to question what was not questioned. They were intelligent, their minds were already disciplined to the clarity of science, and they were sixteen years old. But at this point the pleasure of the argument ceased for Shevek, as it had earlier for Kvetur. He was disturbed.
