I argue that talking about aesthetic injustice implies reflection about some failures on the exercise of aesthetic judgment due to mechanisms of oppression, which have a negative impact on the development of potential aesthetic agents.  I claim that mechanisms of oppression like aesthetic identity prejudice, oppression or lack of recognition of sensitivities, and aesthetic dysfunctionality in sites of enunciation continue undermining the degree of validation of potential aesthetic agents - who mostly belong to historical oppressed groups like women, black people, indigenous, native Americans, among others.  Overall, my aim is to analyze how these mechanisms of oppression continue undermining, marginalizing, and immobilizing the development of potential aesthetic agents. My proposal resides in the idea that these mechanisms of oppression enable aesthetic injustice on three levels: testimonial aesthetic injustice, hermeneutical aesthetic injustice, and aesthetic dysfunction.
