For Hegel, the world in its historical dimension is the dialectical revelation of consciousness to itself. In his curious idiom, the end of history comes when Spirit achieves awareness of its identity as Spirit, not, that is to say, alienated from itself by ignorance of its proper nature, but united to itself through itself: by recognizing that it is in this one instance of the same substance as its object, since consciousness of consciousness is consciousness.

Arthur C. Danto, The Philosophical Disenfranchisement of Art (Columbia University Press, 2005) p. 15

On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant wth its contrary. Machinery, gifted with the wonderful power of shortening and fructifying human labour, we behold starving and overworking it. The newfangled sources of wealth, by some strange weird spell, are turned into sources of want. The victories of art seem bought by the loss of character. At the same time that mankind masters nature, man seems to become enslaved to other men or to his own infamy. Even the pure light of science seems unable to shine but on the dark background of ignorance. All our invention and progress seem to result in endowing material forces with intellectual life, and in stultifying human life into a material force. This antagonism between modern industry and science on the one hand, modern misery and dissolution on the other hand; this antagonism between the productive powers, and the social relations of our epoch is a fact, palpable, overwhelming, and not to be controverted.

Karl Marx, Speech at Anniversary of the People's Paper (1856)

I don't think it's relativism. To say that one needs art, or politics, that incorporate ambiguity and contradiction is not to say that one then stops recognizing and condemning things as evil. However, it might stop one being so utterly convinced of the certainty of one's own solutions. There needs to be a strong understanding of fallibility and how the very act of certainty or authoritativeness can bring disasters.
