Happiness is multiple, conflicting ideas - often changing from context to context with each change presaging a cascade of different meanings and interpretations. In this essay I shall try to link a number of them in a manner that is not causal but, I hope, rather evocative. I want to begin with a specific "Jewish" turn in the history of the concept of happiness at the close of the nineteenth century - one that turns out not to be very "Jewish" (...) in its origin - and conclude with some thoughts on Michael Jackson and our need to understand happiness in the twenty-first century.
