There are many ways to quantify knowledge and its acquisition. Empiricism is the study of knowledge arising from the senses; how we learn about the world through our sensorial encounters. This is a study of the process of throwing, its nature, origin, sensorial mapping and how it can be seen to reflect more widely the experience of being human. What follows is an auto-ethnographic study of my experience of throwing and, at the same time, how this relationship between hand and material can inform my understanding of other related interactions in the world.
