Baudelaire’s modernité investigates art’s relation with its contemporary world. Modern beauty cannot be found simply by copying past models; transient, contingent, historical experience becomes a problem of artistic form.
Clothing, gesture, crowds, and urban life provide materials. Including a period detail does not by itself produce artistic achievement: the question is how transience becomes a meaningful form of experience.
The concept is not unconditional praise of everything new. Attraction and discomfort, proximity and estrangement coexist in Baudelaire’s city. Modernity is not a simple line of progress.
Benjamin reconnects this aesthetic problem with commodification, crowds, and shock. The author’s essay and later historical interpretation thus form a traceable relation without becoming identical.
