Scopitone : nature.

For some, the Earth is a whole that stands as a principle of solidarity between all its cohabitants. Others see it rather as a piece of land that qualifies, or even identifies, those who live there; all the more so, it seems, because they were not born there. So, if listening to the songs does not help to define the word 'nature', it is perhaps also because the interest of the term is not to have one. In this case, the notion of nature is impertinent as a category of scientific analysis. But it is particularly valuable as a political concept, in other words as a social issue: what is 'natural'? Who decides this? Who objects to this?
