Matching Quote

"The word change, so dear to our Europe, has been given a new meaning: it no longer means a new stage of coherent development (as it was understood by Vico, Hegel or Marx), but a shift from one side to another, from front to back, from the back to the left, from the left to the front (as understood by designers dreaming up the fashion for the next season)."

-Milan Kundera
