Answer: By using the study of their environment to overcome the belief that life, diseases and fate were controlled by gods.
Explanation: The Greeks held strong beliefs in mythological beings and gods who interfered with human lives and controlled their fates. Early Science in Greek civilization dates back to Thales, who lived before Aristotles. Thales predicted an eclipse and categorized the states of matter into liquid, gases and solids. 
Aristotle who studied such fields as biology and physics, came up with identifying the building blocks of Logic: that arguments which are logical form a logical conclusion.

Answer:
Plessy v. Ferguson was a landmark 1896 U.S. Supreme Court decision that upheld the constitutionality of racial segregation under the “separate but equal” doctrine. The case stemmed from an 1892 incident in which African American train passenger Homer Plessy refused to sit in a car for Black people. Rejecting Plessy’s argument that his constitutional rights were violated, the Supreme Court ruled that a law that “implies merely a legal distinction” between white people and Black people was not unconstitutional. As a result, restrictive Jim Crow legislation and separate public accommodations based on race became commonplace.
