Often, the first chapter of botanical guides about trees attempts to define what is a tree: a task that should be the job of philosophers according to biologist Francis Hallé. In this research I study tree metaphors and argue that most of them are obsolete.

This ongoing artistic research is expanded without hierarchy between the different theoretical studies in the field of the humanities —Deleuze, Calvino, Dümpelmann— scientific research in the field of urban arboriculture —Hallé, Wohlleben, Drénou— and artistic representations where the tree has an special meaning —Perejaume, Abramović, McCarthy, etc.

I love lectures so much that I've been looking for a way to share this research as a portable slide show. The direct reference is the notebooks used by the FREE TOURS tourist guides. There are two ways to approach the book: as an attendee at a presentation — where only the images would be seen— or as a reader — also reading the "presenter's notes."
