Yap. \:\) I said 'if you want' and if you don't you don't.
I meant that surrealism could be seen as closely related to Dada, as the more intuitive container of the the absurd, die Verfremdung, where as Dada is more cerebral, philosophical, focussed on form and abstractions, but also tending to Verfremdung (is there an English word for this?)
Take Magritte's painting "ceci n' èst pas une pipe" for instance.
I've always liked the Dada mouvement. And Magritte's paintings, though he uses his paint dry and poorly.
