Final answer:
Nietzsche saw modernity as a decline into mediocrity due to Judeo-Christian morality, which subverts natural nobility and favors the weak.
Step-by-step explanation:
Friedrich Nietzsche's critique of modernity postulates that contemporary culture, including art, has been marginalized under the banner of 'culture', a term heavily influenced by Judeo-Christian morality.
This morality, according to him, suppresses the natural nobility of the strong in favor of the weak, inducing a state of mediocrity, degeneration, and decline across various spheres including science, art, and the human body.
Nietzsche perceives modern movements such as feminism, democracy, and universal education as challenges to the ancient order, undermining what he considers the true progress of civilization. He advocates a subjective experience of art and criticizes the mundane approach of his contemporaries.
Nietzsche associates the idea of progress with the propagation of a life-denying morality and suggests the necessity of slavery in cultural production as a means of enhancing human beings, differing markedly from moral valuations of equality and universal rights.
