Beauty

A rebel Dalek, through an accident in its manufacture, had human-like qualities, including the ability to appreciate beauty. It tried to teach other Daleks that beauty had to be preserved and was a strength. The Dalek Emperor reminded them beauty was not eternal or a strength and had the 'diseased' Dalek exterminated, decreeing that beauty was for human beings and human beings were to be destroyed. (COMIC: Shadow of Humanity)

The Prime Minister of the Daleks revealed to the Eleventh Doctor that the Daleks had a concept of beauty, as they admired the "divine hatred" of the residents of Dalek Asylum. (TV: Asylum of the Daleks)

The Dalek Time Controller stated to the Master that they didn't have a concept of beauty. (AUDIO: Master of the Daleks)
