Q1. Which three parts make up Zeno of Citium's system of philosophy as later organized by the Stoics?
  • A. Metaphysics, epistemology, and aesthetics
  • B. Logic, physics, and ethics ✓
  • C. Dialectic, rhetoric, and grammar
  • D. Mathematics, astronomy, and music

Why: The Stoics divided philosophy into logic, physics (the study of nature and the cosmos), and ethics (the study of how to live well). They often compared the system to an egg or a fertile field: logic is the shell or fence, physics the white or soil, and ethics the yolk or the fruit.

Q2. According to the Stoic analogy often attributed to Zeno and his successors, which part of philosophy corresponds to the fruit of a tree?
  • A. Logic
  • B. Physics
  • C. Ethics ✓
  • D. Dialectic

Why: The Stoics compared philosophy to a fruit-bearing tree or a living creature. Logic is the protective bark or hedge, physics the wood or soil, and ethics the fruit, which represents the ultimate goal of philosophy: living virtuously.

Q3. In the Stoic system, what is the role of logic?
  • A. It studies the motions of the heavenly bodies
  • B. It provides the tools for reasoning and distinguishing true from false impressions ✓
  • C. It determines the proper duties of citizens in the state
  • D. It explains the origin of the gods

Why: Logic in Stoicism covered rhetoric, dialectic, and the theory of perception and assent. It was considered necessary to protect and sharpen reasoning, since Stoics held that correct judgments about impressions are the basis of good conduct.

Q4. Why did the Stoics consider physics important for ethics?
  • A. Because the study of nature was needed to predict the weather for farming
  • B. Because understanding the rational order of the cosmos shows that living according to nature means living according to reason ✓
  • C. Because physical strength is required to practice virtue
  • D. Because ethics was considered a branch of medicine

Why: Stoics held that the universe is governed by a rational divine principle, the Logos. Knowing this order through physics reveals that human reason is part of the cosmic whole, so living virtuously means living in accordance with nature and reason.

Q5. What did Zeno of Citium identify as the ultimate goal of human life, which ethics is meant to achieve?
  • A. Pleasure and freedom from pain
  • B. Wealth and social status
  • C. Living in agreement with nature, which is virtue ✓
  • D. Fame and the admiration of others

Why: Zeno taught that the goal of life is to live in agreement with nature, which amounts to living virtuously. Virtue alone is good, and it is sufficient for happiness, while externals like health or wealth are only preferred or dispreferred indifferents.

Q1. According to Zeno of Citium, what is the only thing that is truly good?
  • A. Pleasure and the absence of pain
  • B. Virtue ✓
  • C. Wealth and social reputation
  • D. Health and physical strength

Why: Zeno held that virtue alone is good, while things like health, wealth, and reputation are 'preferred indifferents' that have value only in relation to how they are used in accordance with virtue.

Q2. Which term do Stoics use for external things like health, wealth, and reputation that are neither good nor bad in themselves?
  • A. Eudaimonia
  • B. Apatheia
  • C. Preferred indifferents ✓
  • D. Logos

Why: Zeno called these 'indifferents.' Some, such as health and wealth, are 'preferred' because they are natural advantages to select, but they do not make a person good or bad.

Q3. What did Zeno identify as the ultimate goal of human life?
  • A. Accumulating the greatest possible pleasure
  • B. Living in agreement with nature, which means living virtuously ✓
  • C. Achieving political power in the city-state
  • D. Avoiding all contact with the physical world

Why: Zeno taught that living 'in agreement with nature' is the goal, and since human nature is rational, this amounts to living virtuously, governed by reason.

Q4. Which four cardinal virtues are central to Zeno's ethical vision as later developed by the Stoics?
  • A. Courage, strength, speed, and beauty
  • B. Wisdom, justice, courage, and temperance ✓
  • C. Faith, hope, charity, and humility
  • D. Piety, loyalty, honor, and wealth

Why: Wisdom, justice, courage, and temperance (self-control) form the core of Stoic virtue. Each is a form of knowledge about what is good, bad, or indifferent in a given situation.

Q5. Why did Zeno regard emotions such as grief and fear as obstacles to virtue?
  • A. Because they are pleasurable and distract from duty
  • B. Because they arise from false judgments about what is good or bad ✓
  • C. Because they are a sign of divine punishment
  • D. Because they weaken the body's natural defenses

Why: Stoics held that passions (pathē) result from mistaken judgments that external things are truly good or bad. Correcting these judgments through reason leads to a state of freedom from disturbing emotion, called apatheia.
