Aristotle was a Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, whereafter Proxenus of Atarneus became his guardian.

Aristotle's contribution to science of all times can't be overestimated. He shaped the views of medieval scholars, whose influence extended into the age of Renaissance. These beliefs were finally changed only under the Enlightment. Aristotle was actually one of the first scientists to study logic, which laid the groundwork for the modern formal logic, appeared during the last years of the 19th century.
