Post Aristotelian Philosophers – Ethics Notes

The era following Aristotle witnessed a myriad of thinkers who, while influenced by their predecessors, charted new territories in the realm of philosophy. This post-Aristotelian epoch was marked by seminal contributions that continue to reverberate through modern ethical discourse. In this article we will discuss which will be helpful for UPSC exam Ethics, Integrity & Aptitude (GSIV) preparation.

Post Aristotelian Philosophers - Background

  • Ancient Greek philosophy entered a period of disintegration after Aristotle, when it lost its novelty and vitality.
  • Political, social, and moral environments were no longer able to support philosophical thought's innovative tendencies.
  • Macedonia ruled over all Greek city-states with the exception of Sparta. Their prior freedom was never regained.
  • Later, Rome annexed Greece as a province. In any case, the moral and social vigor of the 'delicate and lovely' Greek civilisation was vanished.
  • Philosophy during this time focuses mostly on assisting the individual in escaping from life's difficulties.
  • It revolves around the individual man, his destiny, and his spiritual well-being.
  • Philosophy developed to become a solace for the disturbed mind and a secure anchor for men fleeing the storms of life.

Approach of Post Aristotelian Philosophers

  • Philosophers developed an obsession with ethical issues due to their singular focus on the individual subject.
  • Earlier, philosophers like Xenophanes and Anaxagoras advanced audacious hypotheses on the universe's beginnings and nature.
  • However, Aristotelian thinkers were not particularly interested in cosmogony. This strategy constrained their thinking.
  • Because nobody who is overly self-conscious and unable to lose themselves in thoughts about the cosmos or bigger issues can come up with fresh ideas.
  • Therefore, the great metaphysical theories of Plato and Aristotle, which were comprehensive and profound, could not be matched by later Greek thinkers.
  • The post-Aristotelian philosophers considered ethics to be superior to other fields of knowledge like logic, metaphysics, and physics.
  • These areas possessed no intrinsic value to them and served only as the foundation for their moral arguments. They promoted extreme and biased moral beliefs.
  • They inserted subjectivity even into the core of philosophy or the theory of knowledge.
  • Truth was no longer regarded as being unbiased and separate from one's own goals or intentions.
  • Nothing is true or moral in and of itself; truth has become an expression of personal opinion.
  • In a similar vein, the skeptics were a school of thinkers who rejected the idea that knowledge could be attained. This is another example of one-sided philosophy.
  • Neo-Platonism, "with its fantastic paraphernalia of sorcery, demons and demi-gods," is another example of the irrationality of philosophical thought during this time.

Important Post Aristotelian Philosophers

Epicureanism

  • Epicureanism is a philosophical system based on Epicurus' beliefs, and it was one of the most popular schools of Hellenistic philosophy (together with Platonism and Stoicism).
  • It was established approximately 307 B.C.E., when Epicurus began teaching.
  • He claimed that happiness was the ultimate objective of human life, and that the highest good was to pursue small pleasures in order to achieve a condition of tranquillity and freedom from anxiety via knowledge as well as the absence of pain.
  • Epicureanism teaches that the highest good is to pursue simple pleasures in order to achieve a condition of calm, freedom from fear ("ataraxia"), and absence of physiological suffering ("aponia").
  • This combination of moods is seen to be the ultimate kind of happiness, and so Epicureanism might be regarded as a version of Hedonism, albeit it varies in its definition of happiness as the absence of suffering and its promotion of a simple existence.
  • Epicureanism was popular for ages but never made it into the mainstream of intellectual thought.
  • One explanation for this is that it was resisted by conservatives and was eventually repressed by the Christian religion.
  • Some of its principles would subsequently play a role in the Renaissance and impact modern thinkers, notably in the fields of civic justice and physics.
  • Epicureanism has made significant contributions to modern philosophy in numerous ways.
  • One of these was the "atomism" theory, which was adopted by early physicists and chemists as they attempted to develop contemporary atomic theory.

Stoicism

  • Stoicism promotes self-control and fortitude as a method of conquering negative emotions; the philosophy claims that becoming a clear and unbiased thinker permits one to perceive the universal reason.
  • Stoicism was a Hellenistic philosophical school that flourished in the Roman and Greek worlds until the third century AD.
  • Stoicism is primarily a philosophy of personal ethics, guided by its logic system and views on the natural world.
  • According to stoicism, the path to happiness for humans as social beings is found in accepting what we have been given in life, not allowing ourselves to be controlled by our desire for pleasure or fear of pain, using our minds to understand the world around us and to contribute to nature's plan, and working together and treating others fairly and justly.
  • Scholars recognise three major phases of ancient Stoicism: the early Stoa, from Zeno of Citium (the school's founder, c. 300 BCE) to the third head of the school, Chrysippus; the middle Stoa, including Panaetius and Posidonius; and the Roman Imperial period, or late Stoa, with Seneca, Musonius Rufus, Epictetus, and Marcus Aurelius.
  • Stoicism evolved from preceding schools of thought, and its impact continued well beyond the formal closure of the ancient philosophical schools by the Byzantine Emperor Justinian I in 529 C.E.
  • Stoicism was a major philosophical system throughout the Hellenistic period.
  • The name comes from the porch in Athens' Agora, which was covered with mural paintings and used as a gathering place for the first generation of Stoic philosophers to teach.
  • Stoicism has run through the veins of many of history's great leaders. It has been used by kings, presidents, artists, authors, and business owners.
  • The school of thought developed there outlasted the physical Athenian porch and was prominent well into the Roman period and beyond.

Utilitarianism

  • Utilitarianism is a moral and ethical philosophy that focuses on maximizing overall happiness and well-being for the greatest number of people.
  • Developed by philosophers such as Jeremy Bentham and John Stuart Mill, utilitarianism has emerged as a significant ethical theory with far-reaching implications.
  • Utilitarianism is basically the principle of maximizing happiness and minimizing suffering for the greatest number of individuals.
  • This ethical framework emphasizes the consequences of actions, evaluating their overall utility or usefulness.
  • The fundamental idea is to promote actions that generate the greatest amount of happiness or well-being while minimizing any potential harm or unhappiness.

Kantianism

  • Kantianism is a philosophical framework that highlights moral duty and rationality as the basis for ethical decision-making.
  • Developed by the renowned German philosopher Immanuel Kant, this ethical theory provides a unique perspective on moral principles and the universal nature of human obligations.
  • Kantianism focuses on the intrinsic worth and dignity of every individual, advocating for actions guided by moral duty rather than personal interests or consequences.
  • At its core, Kantianism asserts that actions should be guided by moral principles and universal moral laws rather than personal desires or consequences.

Skeptics

  • It was founded by Pyrrho. Sextus Empiricus was another prominent proponent.
  • Skeptics questioned the certainty of knowledge.
  • They believed that every assertion can be countered with an equal and opposite assertion, leading to suspension of judgment.
  • Skepticism plays a significant role in the scientific method, demanding evidence and promoting inquiry.

Plotinus and Neo-Platonism

  • While influenced by Plato, Plotinus is the primary figure associated with Neo-Platonism.
  • Neo-Platonism introduces the One, an ineffable, all-encompassing source of reality.
  • The soul's journey towards the One and away from the material world forms the crux of this philosophy.
  • Neo-Platonism significantly influenced Christian, Islamic, and Jewish mystical thought.

Conclusion

Post-Aristotelian philosophy, rich and varied, was built on past legacies while introducing transformative ideas. The post-Aristotelian era, brimming with rich philosophical treatises, not only transformed Western ethical thought but also found resonances in global traditions. The universality of their explorations signifies the shared human quest for meaning and morality.

GS Mains Questions and Model Answers

Q1: Critically examine the ethical philosophy of Stoicism and its relevance in modern life.

Answer: Stoicism, founded by Zeno of Citium, emphasizes virtue and self-control as the keys to achieving happiness. It teaches that happiness is not determined by external circumstances but by one’s own rational control over emotions and reactions. This philosophy encourages resilience in the face of adversity and advocates living in harmony with nature and reason. In modern life, Stoicism remains relevant, especially in its focus on emotional intelligence, self-discipline, and mental fortitude, offering valuable insights for handling stress, uncertainty, and personal challenges.

Q2: How did post-Aristotelian philosophers like Epicurus and Zeno of Citium influence modern ethical thought?

Answer: Post-Aristotelian philosophers such as Epicurus and Zeno of Citium laid the foundation for modern ethical thought through their emphasis on individual happiness and virtue. Epicurus’ philosophy of pleasure as the highest good influenced utilitarian thought, while Stoicism’s emphasis on virtue and rational control paved the way for modern concepts of resilience and emotional intelligence. Their ideas about personal well-being, virtue ethics, and the importance of internal control continue to shape contemporary ethical theories, particularly in the areas of psychology, self-help, and moral philosophy.

Q3: Discuss the impact of Stoic philosophy on the development of Western political and ethical thought.

Answer: Stoic philosophy, with its emphasis on virtue, justice, and rationality, had a profound impact on the development of Western political and ethical thought. Stoic principles of fairness, equality, and self-governance influenced later political thinkers like Cicero, who advocated for the idea of natural law, and Roman leaders like Marcus Aurelius, who integrated Stoic ethics into governance. The Stoic idea that virtue is sufficient for happiness contributed to the development of modern ethical frameworks that prioritize individual responsibility, justice, and rational decision-making, laying the groundwork for Enlightenment values and contemporary democratic principles.
