Transcript of Aristotle
Natural Motion: Motion that is straight up or straight down.
Violent Motion: Motion resulting from an external push or pull.
Aristotle was the first to think quantitatively about the speeds involved in these movements.
Do moving things really require force to keep moving?
Do heavy objects really tend to fall faster than lighter objects? Personal Information: Had a stutter & described the stutterer tongue as “too sluggish to keep pace with the imagination.” Tutored Alexander the Great Started his own school in Athens Lyceum 335 B.C. Born 384 BC in Northern Greece His Father was a Doctor Research Cont. Aristotle's Method of Investigation *1>Defining the subject matter. 2>Considering the difficulties involved by reviewing the generally accepted views on the subject. 3>Presenting his own arguments and solutions.
*This is the pattern modern research papers follow, Aristotle was laying down the standard professional approach to scientific research.
*The arguments he used were of two types: dialectical, that is, based on logical deduction; and empirical, based on practical considerations. Study of Geology Aristotle's research in sciences included a study of geology. He classifies animals into genera based on their similar characteristics. *Example: He classified animals into species based
on those that had red blood and those that did not.
*The animals with red blood were mostly vertebrates and the "bloodless" animals were labeled
Cephalopods. This classification was regarded as the standard system foe hundreds of years. Scientific Facts *Elements- Aristotle assumed all substances to
be compounds of four elements: earth, water, air
and fire, and each of these to be a combination of two
of four opposites, hot and cold, and wet and dry. He discussed the properties of real substances in terms of their “elemental” composition at great length, how they reacted to fire or water, how, for example, water evaporates on heating because it goes from cold and wet to hot and wet, becoming air, in his view. Biology Aristotle’s really great contribution to natural science was in biology.
Even though he was not known for experiments, He was the first to use dissection extensively. Scientific Facts Aristotle's study of nature was a search for "causes." He stated that any object, animal, or plant had four attributes. (Matter, Form, Moving Cause, and Final Cause. Aristotle created the scientific method. His influence served as the basis for much of the
science and philosophy thousands of years later. Life at Aristotle's house known to walk around the school grounds while teaching, his students, forced to follow him, were nicknamed the “Peripatetics,” meaning “people who travel about.” Pythias wished to have her bones interred with those of Aristotle when he died, and Aristotle was to remember her request many years later when he came to write his will. After Pythais death he had a relationship with Herpyllis, a handmaiden of Pythais & had another son. Happiness depends upon ourselves. - Aristotle
