"From the point of view of scientific analysis, the term “finalism” should not be too surprising, if it does not refer to an intentional purpose, but only to an interpretative strategy. The action of finalistic principles, in fact, is not new to other fields of science. Mathematical physics knows the principle of least action, which indicates how a physical system always takes the most advantageous path. The principles of classical thermodynamics are essentially finalistic principles, and chemistry also uses them when explaining chemical bonds, starting from the principle that each atom tends to complete its eight fundamental electron orbitals."
