Irrationality

In the preamble of the book on Irrationality (by Justin Smith)...

At the individual level irrationality manifests itself as dreams, emotion, passion, desire, affect, enhanced by drugs, alcohol, meditation; at the social level it is expressed as religion, mysticism, storytelling, conspiracy theory, sports fandom, rioting, rhetoric, mass demonstrations, sexuality when it bursts out of its prescribed roles, music when it breaks away from the notes on the sheet and takes on a life of its own.

Perfect recipe for speaking of Romanticism!
