Final answer:
Newton and Galileo Galilei were not philosophers of Greece's Classical Age; they contributed to science in the 16th and 17th centuries, which was long after the Classical Age, noted for figures like Socrates, Plato, and Aristotle.
Step-by-step explanation:
The Classical Age of Greece, specifically between the triumph against Persia in 479 BCE and the conquest by Philip II in 338 BCE, is renowned for its significant contributions to art, literature, and especially philosophy. Socrates, Plato, and Aristotle are typically considered the pillars of Greek classical philosophy.
Their work primarily focused on ethics and politics, and they engaged deeply with questions about whether social customs and political institutions were dictated by nature or merely human constructs.
However, during the Hellenistic period, following the classical era, philosophers shifted their focus to personal ethics and how to live a content life. Notable schools of thought from this period include the Epicureans, Stoics, and Cynics, which addressed achieving happiness and tranquility rather than the earlier practices of classical philosophers.
In contrast to the renowned figures of the Classical Age, philosophers such as Newton and Galileo Galilei, who contributed significantly to the foundation of modern science, were not part of Greece's Classical Age. They lived much later and were instrumental in the scientific revolution during the 16th and 17th centuries.
