In Britain, from the middle of the nineteenth century on, scientific discoveries (e.g. anaesthesia) and theories (e.g. evolution theory) fundamentally changed the way humanity perceives of itself; science engendered a controversial cultural debate on the human condition and on humanity s position in nature (or creation ) that is still on-going. On the basis of a large corpus of Victorian periodicals for young readers, the project will examine the treatment of natural and human sciences (i.e. biology, medicine, ethnology, anthropology) and the extent to which this treatment reflects and positions itself within this public debate.
