Central Problem
Epicureanism addresses the fundamental question of how human beings can achieve genuine happiness and tranquility in a world filled with fears, anxieties, and unfulfilled desires. The central problem is threefold: How can we liberate ourselves from the paralyzing fears of the gods, death, and the afterlife? How can we understand the nature of pleasure and pain so as to live well? And how can we navigate our desires to achieve lasting contentment rather than perpetual agitation?
Epicurus recognized that most human suffering derives not from actual physical pain but from mental disturbances—anxieties about divine punishment, terror of death, endless pursuit of unnecessary pleasures, and fear of uncontrollable pain. These psychological afflictions prevent people from achieving the serene life that should be philosophy’s ultimate goal. The challenge was to develop a comprehensive philosophical system—encompassing epistemology, physics, and ethics—that could serve as a “quadruple medicine” (quadrifarmaco) capable of curing these spiritual maladies.
Unlike the Stoics who sought harmony with cosmic reason, Epicurus sought liberation from cosmic fears altogether, teaching that neither gods nor death nor the pursuit of excessive pleasure should disturb the wise person’s tranquility.
Main Thesis
Epicurus maintains that philosophy’s sole purpose is instrumental: to provide the means for achieving happiness, understood as liberation from mental disturbance (ataraxia) and bodily pain (aponia). This therapeutic conception of philosophy yields the famous “quadrifarmaco” or fourfold remedy:
First Medicine: The gods exist but do not concern themselves with human affairs. Living in perfect bliss between worlds, they neither reward nor punish mortals. Therefore, fear of divine intervention is groundless.
Second Medicine: Death is nothing to us. Since death is merely the dissolution of atoms and the cessation of sensation, “when we exist, death is not present; when death is present, we no longer exist.” Fear of death is therefore irrational.
Third Medicine: Pleasure, properly understood, is easily attainable. True happiness requires only the satisfaction of natural and necessary desires, which are modest and readily fulfilled.
Fourth Medicine: Pain, when severe, is brief (leading either to death or recovery); when chronic, it is bearable. Therefore, fear of unbearable suffering is unfounded.
The physical foundation for this ethics is a modified atomism derived from Democritus. All reality consists of atoms moving through infinite void. However, Epicurus crucially introduces the concept of clinamen (atomic swerve)—a spontaneous, uncaused deviation in atomic trajectories that breaks deterministic necessity and makes human freedom possible.
The ethical goal is negative pleasure—not the pursuit of intense sensations but the absence of pain and disturbance. The wise person achieves self-sufficiency through rational calculation of pleasures, limiting desires to what is natural and necessary, and cultivating friendship as the supreme social good while avoiding political entanglements.
Historical Context
Epicurus (341-271 BCE) lived during the turbulent transition from the Classical to the Hellenistic period. Born on Samos to Athenian colonists, he witnessed the aftermath of Alexander‘s conquests and the fragmentation of his empire among warring generals. The old certainties of the Greek polis had collapsed; citizens of small city-states now found themselves subjects of vast monarchies over which they had no control.
In this context of political powerlessness and social upheaval, Epicureanism offered a philosophy of strategic withdrawal. Around 307-306 BCE, Epicurus established his school in Athens in a garden (hence “philosophers of the Garden”), creating an alternative community based on friendship and philosophical practice rather than civic engagement.
The school was remarkably inclusive for its time: women and slaves could participate as equals, united by bonds of philosophical friendship. The community venerated Epicurus almost as a divine figure, following his precept: “Act always as if Epicurus were watching.” This reverence ensured doctrinal stability—unlike other Hellenistic schools, Epicureanism remained remarkably faithful to its founder’s teachings for over five centuries.
The Roman poet Lucretius (96-55 BCE) transmitted Epicurean physics and ethics in his masterpiece De rerum natura, presenting Epicurus as humanity’s liberator from superstition and the fear of death. The poem became the primary source for Epicurean thought in the Latin West.
