What is a thing? Every action and practice involves physical things — this could be our bodies, a tool or some aspect of the environment. In each of these cases a thing has three qualities:
1. It has Necessary Physical Properties: those parts of itself that were deliberately made.
2. Necessary Physical By-Products: To make anything there will always be many necessary by-products. The thickness of a coffee cup is a by-product of developing a cup that insulates.
3. Chance physical by-products: When that same ceramic coffee cup accidentally falls — the shards are chance physical by-products.
An active X.
Things are not passive nor are they our intentions.
