This presentation revolves around the assertion that in the 21st century, humanity lives in a state of cultural cosmopolitanism. The concept will be discussed and analyzed along two dimensions. The aesthetic dimension, relating to creative artefacts and objects of taste, and the tacit or embodied knowledge dimension, relating to cultural practices in everyday life. I will talk about the global cultural public sphere as the space fostering cultural cosmopolitanism. Examples will be drawn from the cases of popular music, food and clothing.
