In the dialogue 'Euthyphro', Socrates engages in a philosophical inquiry regarding the nature of piety. He questions Euthyphro, who is on his way to prosecute his own father, about the definition of holiness and the relationship between human moral duties and divine commands, famously asking whether the pious is loved by the gods because it is pious, or is pious because it is loved by the gods.

Ethics is often viewed as prior to political science because it establishes the moral foundations and normative goals that political systems aim to achieve. While political science studies the structures and processes of governance, ethics provides the criteria for evaluating whether those systems are just, virtuous, or conducive to human flourishing. Thus, political inquiry is fundamentally rooted in ethical considerations regarding the 'good life' and justice.

Socrates attracted a diverse group of followers in Athens, including notable figures such as Plato, who became his most famous student, as well as political figures like Alcibiades and Critias. These individuals were drawn to his unique method of questioning and his challenging views on politics and morality. Their diverse paths, ranging from philosophical writing to political leadership, reflect the broad impact Socrates had on his contemporaries.

Socrates is widely recognized as the foundational figure in Western philosophy who mentored several influential thinkers, including Plato and Xenophon. Both authors documented Socratic dialogues and his philosophical method, which emphasized questioning and ethical inquiry. Their writings remain the primary historical sources for understanding Socratic thought and his impact on the development of political and moral philosophy in ancient Athens.

Socrates famously argued that knowledge is virtue and that wisdom is the essential guide for the soul. He believed that without wisdom, even positive traits could be misapplied, whereas wisdom ensures that all actions and experiences are directed toward the ultimate good, which he identified as happiness or eudaimonia.

In the Theaetetus, Socrates engages in a rigorous examination of the definition of knowledge. The dialogue explores various theories, such as knowledge as perception, true belief, and true belief with an account. It is a foundational text in epistemology, where Socrates seeks to distinguish genuine knowledge from mere opinion, a theme central to his broader philosophical project regarding truth and wisdom.

Socrates posits that wisdom is the essential guide for the soul. When actions are directed by wisdom, the soul can navigate life's hardships effectively. Wisdom ensures that the soul chooses the correct path, leading to eudaimonia, or true happiness, as it aligns human behavior with the rational order of the universe rather than mere impulse or ignorance.

Meno's paradox, also known as the learner's paradox, questions how inquiry is possible. If one does not know what they are looking for, they cannot recognize it when they find it; if they already know it, they do not need to look for it. Socrates addresses this through the theory of recollection.

Protagoras was a prominent Sophist who traveled throughout Greece teaching rhetoric and virtue for high fees. While Plato often criticized the Sophists for their relativism and focus on persuasive speech over objective truth, historical accounts acknowledge Protagoras as a wealthy and influential intellectual figure of his time.

Ancient Greek political thinkers, particularly Socrates, Plato, and Aristotle, viewed the state as an ethical association aimed at achieving the 'good life' for its citizens. They believed that politics was inseparable from ethics, and the ultimate purpose of the political community was to foster virtue and enable individuals to realize their full potential within a well-ordered society.
