The word "mechanical" comes from a greek word meaning " machine".
However, the received definition of mechanical philosophy does not contain the concept of a machine. This school of thought is said to adopt the priciple according to which
everything in nature can be explained by the size, the shape and the movement of bodies or material objects ( one body acting on the other, through collision)
My question : which concept of a " machine " allows to call "mechanical" such a principle.
