Aristotle's Aetiology

Although Aristotle is well known as a philosopher, scientists acknowledge his influence in almost every branch of the sciences. He definitely benefited from Plato (his teacher) on matters of the politis and the personality characteristics of the individual.
What many modern thinkers forget is the impact that Aristotle made with his research into the specific sciences. In his Athenian academia, or Lyceum, Aristotle established his unique method of teaching - the peripatetic.
Many of his biological experiments were backed by specimens sent to him by his ex-pupil Alexander the Macedonian. It is said that Alexander the Great collected samples from every country he conquered and forwarded them to his tutor.
Aristotle established a scientific methodology which, even in modern days, influences the academic world. His research in biology, his writings in physics, and his afterthoughts (meta-after) his papers and lectures on physics (metaphysica) undoubtedly made an impact on the method of treating people.
