ABSTRACT
This chapter discusses the aim and locomotion of animals in an asymmetrical headfirst direction, whose biomechanics is describable by linear momentum and whose primary symmetry operation is called a translation. It shows various nature writers who develop a natural philosophy of aim, as animals get ready to move, and as humans get ready to act. Over and over, nature writers use the readiness to act as a characteristic of animal motion. The chapter also shows that it is a synonym for the scientist's definition of "potential energy." It looks for the symmetrical shapes of balance and angular momentum in the morphological body plan of a headfirst anteriority, but now from the point of view of discerning the environmental mold. The chapter emphasizes that movement in a straightforward direction, so the relative movement in the medium is a reversed straight line. This chapter presents an overview of the key concepts discussed in this book.
