Final answer:
The claim that postmodernism advocates for no appropriate landscape appreciation is false; postmodernism acknowledges multiple perspectives, and artists have historically challenged the establishment to recognize the value in landscape art.
Step-by-step explanation:
The statement suggesting that according to Carlson, on the postmodern view of landscape appreciation there is no appropriate appreciation of landscapes and thus no correct curriculum for landscape appreciation is false. Postmodernism encompasses a wide array of perspectives, and it does not necessarily imply the absence of appropriate forms of appreciation. Artists like Courbet, Manet, and the Impressionists revolutionized the art world by challenging the prevailing hierarchies of the Academy, which favored history painting over other forms. These artists validated the significance of landscapes and genre scenes, showing that all subject matter could carry worth and merit artistic appreciation. Therefore, postmodernism may offer various avenues for appreciating landscapes, rather than none.
