Criticism (n.) is best when it dissolves considerations of content into those of form.
Criticism (n.) is always projected self-criticism. One criticizes in others what one recognizes and despises in oneself.
Criticism (n.) is an act of intellectual disburdenment; less about resolving alluring and troubling problems than of using them up.
Criticism (n.) is best pursued not as a hermeneutics but as an erotics of art; showing how the work of art is what it is, even that it is what it is, rather than to show what it means.
Criticism (n.) is good when it simply supplies a really accurate, sharp, loving description of the appearance of a work of art; revealing the sensuous surface of art without mucking about in it.
Criticism (n.) is tasked to recover our senses; not to find the maximum amount of content in a work of art, but to cut back content so that we can see the thing at all.
