Improvisation is the origin of art and science, tragedy and comedy, acting and doing, of the self as improvising and improvised. But clearly we cannot use improvisation to explain improvisation. We cannot be satisfied with an argument that improvisation is, well, improvisational--nor simply free-play. Rather, improvisation as αὐτο-σχεδιάζεῖν, means self-schematization.

The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs. An illuminating general Introduction describes the book that lies ahead, explaining what sort of work it is and what sorts of evidence it relies on. (shrink)
