What Makes the Wood Act Like a Chair?

Aristotle was interested in how things grow. And he noted the role that form had in growth and development. So for example, i can have a block of wood, right? And i can make it into a chair, or perhaps a table, or if it's big enough amount of wood, i can made it into a ship or a boat. And aristotle askd what makes the wood behave like a chair, as opposed to a table or to a ship? This is where we get the notion of actuality from. We often use the word actuals as a way of talking about ness. It's an actual something.
