A problem of representation. In the 19th century, Courbet led fine arts to leap beyond representation of the visual forms into representation of social realities. Shortly after, in the field of literature, Lukacs posed a higher requirement for Realism: the duty of art is to give a truthful representation of the real world.

在此之前，关于艺术与现实的关系的思考一直停留在视觉层面，即再现的问题上，而库尔贝使美术从视觉再现意义上的真实走向了社会表征意义上的现实，之后，在文学领域中，卢卡奇对现实主义又提出了更高的要求："艺术的任务是对现实整体进行忠实和真实的描写。"
