Artists have their existential questions as human beings, and they address these questions in their works. But they are also thinking in a broader sense when they participate in a social and political debate through their works. Often the most important voices of artists in the political and the social debate are focused on originality in their works. We can see this in historical pieces, like "Guernica" by Picasso. "Guernica" was an extremely important manifestation and critique against war, but it was important and powerful because it was also an incredibly original and powerful work of art.
