WHITE SWANS, BLACK SWANS

In a different manner, starting from Nassim Nicholas Taleb's, Black Swan', the present paper offers fundamental notions about economy, in a more accessible and self ironic manner, underlining, once again, the fact that relativity and subjectivity are here at home, which also explains the difficulty of making forecasts. The accent falls on the recent crisis, which has affected so many innocent people, and the author addresses the responsibility of the economist, but also our responsibility for our own behaviour. A certain cyclicity is invoked, an alternation of, white swans. and, black swans., to finally conclude that all swans are grey.
