‘nature’: is the shape or form which is specified in the definition of the thing All natural bodies and magnitutdes we hold to be as such capacble of locomotion; ofr nature we say is their principle of movement. But all movement that is in place, all locomotion as we term it, is either straight or circular or a combination of these two which are the only simple movements. The reason of this is that these two, the straight and the circular line are the only simple magnitudes.

No revolution about the center is circular motion, while the upward and downward movements are in a straight line, ‘upward’ meaning motion away from the centre, and ‘downward’ motion towards it. All simple motion, then, must be motion either away form or towards or about the centre. This seems to be in exact accord with what we said above - As body is found its completion in three dimensions, so its movement completes itself in three forms - The four elements have only straight line (up or down) motion naturally - Map: square within a square with four unchanging and stable qualities - But since the two straight-line motions (up and down) are natural to the four elements, there must be a fifth element that moves in circles. Matter – form hylomorphism Knowledge: the first grasp the ‘why’ which is to grasp its primary cause 4.1 Aristotle Biology The Aristotelian Corpus Logic (6 books) Metaphysics (1 book) Ethics/Politics (3 ish) Rhetoric and Poetics (2-3) Natural Philosophy (17) What is the history of animals? - A taxonomy like Linnaeus or his successors would mean? o Pick some characteristics o Group things together accordingly DKPCOFGS - This can be taken as either o Just nomenclature o Or trace genetic relationships (we know how and to what it is related) - Locomotion as taxonomic hierarchy Some creatures are gregarious, come are solitary, whether they be furnished with feet or wings or be fitted for a life in the water ; and some partake of both characters, the solitary and he gregarious. And of the gregarious, some are disposed to combine for social purposed, others to live each for its own self Gregarious creatures are - Among birds such as pigeon, the crane and the swan o No bird furnished with crooked talons is gregarious. - Of creatures that live in water, many fish such as tuna and bonito - People present a mixture of the two characters, the gregarious and the solitary Is it a natural history in the sense of a complete description of each animal? - Too jumbled and incomplete How do animals differ and why? What characteristics tend to overlap? Never? Are widespread? Unique? Note: groups are categorized using the concepts of genus and species but not OUR genus and species

Gregarious = genus bird = species Bird = genus pigeon = species Birds = genus furnished with crooked talon = species What properties belong to the genus of birds that also belong to other genera? what are the defining attributes of birds? Differences are there between species of birds? WHY?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
