This chapter focusses on the ornament and its ethical dimension in the modern and contemporary age. Ornament is woven into the fabric of the concept of construction in the period we are considering, creating a harmonious architectural whole, while the spirit of the age and of mass production contribute to the resolution of the contradictoriness described. The ethical dimension of contemporary architecture spends itself in psychoanalytical views of space that, for all their social content, are entrenched on the scale of the individual, with the result that innovative architectural experiments. It concern the attributions of meaning to ethic and ornament in those two periods and the recognition and critique of different architectural visions relating to those concepts. In the post-humanist era, as it is commonly described, the concept of ethics is defined differently than it was in modernity. In post - modernity, the ethic of autonomy-propriety is replaced by the ethic of independence, of multiple deviant truths, of desire.
