If curiosity and attention need cultivation and direction, they also need protection. Rousseau sees a particular risk with the sciences – and this is one which online learning surely magnifies, not diminishes. He puts it beautifully, describing the entry into science as something that can be like entering “into a bottomless sea…When I see a man, enamoured of the various kinds of knowledge, let himself be seduced by their charm and run from one to the other without knowing how to stop himself, I believe I am seeing a child on the shore gathering shells and beginning by loading himself up with them; then, tempted by those he sees next, he throws some away and picks up others, until, overwhelmed by their multitude and not knowing anymore which to choose, he ends by throwing them all away and returning empty-handed.” (172)
