This is a letter. Or rather, the first in a series of letters to be published through the next two years. Together they will attempt to address what I see as an urgent need of the contemporary circus landscape in which we work: that is, the need to redefine what we do. To talk about how we do it. To search for answers to the question of why we do it. And, last but not least, to develop complex and diverse tools that help us to do it.
