Quote of the day by Greek philosopher Epicurus: ‘Is God willing to prevent evil, but not able? Then he is not…’ – The ancient question that still challenges belief

Some questions refuse to grow old. They survive empires, religions, scientific revolutions and centuries of philosophical debate because they touch something deeply human: if a powerful and benevolent God exists, why does evil exist?

More than 2,000 years ago, the Greek philosopher Epicurus was associated with a series of questions that would become one of the most enduring formulations of what is now known as the problem of evil. The argument asks readers to consider a seemingly impossible tension between God's power, goodness and the existence of suffering.

The passage remains striking because it does not offer an easy answer. Instead, it forces a difficult question: Can unlimited power and perfect goodness coexist with a world in which suffering and evil are real?

Quote of the day by Epicurus

“Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?”

Who was Epicurus?

Epicurus was born in 341 BCE and died in 270 BCE, making him one of the most influential philosophers of the Hellenistic period. His philosophy was built around a deceptively simple goal: how can human beings live a happy and peaceful life?

Epicurus was born to Athenian parents on the island of Samos. According to the ancient biography preserved by Diogenes Laertius, he came to Athens at the age of 18 and later studied philosophy, including ideas associated with the atomist tradition. After teaching in several places, he returned to Athens around 307/306 BCE, where he established his philosophical school in a property known as the Garden.

The Garden became more than a place of philosophical instruction. It represented a community built around friendship, philosophical discussion and a simple way of life.

Epicurus is often misunderstood as a philosopher who encouraged constant indulgence and luxury because he considered pleasure the highest good. In reality, his understanding of pleasure was considerably more restrained. He argued that a good life involved freedom from physical pain and mental disturbance, rather than an endless pursuit of material gratification.

The surviving works and sayings of Epicurus are known principally through sources such as Diogenes Laertius, including his Letter to Menoeceus, Letter to Herodotus, Letter to Pythocles and collections of his Principal Doctrines and Vatican Sayings.

What does the quote mean?

Although the passage is traditionally attributed to Epicurus and is widely known as the Epicurean paradox or problem of evil, the wording above does not survive in any extant work by Epicurus. The argument is preserved in the writings of the Christian author Lactantius, who attributed a version of the argument to Epicurus.

At its heart, the argument examines three characteristics traditionally associated with God: omnipotence, benevolence and the existence of evil.

The force of the argument lies not necessarily in providing a definitive disproof of God, but in putting pressure on a particular conception of an all-powerful and perfectly good deity.

For centuries, philosophers and theologians have responded to this challenge in different ways. Some have argued that suffering may be connected to human free will; others have suggested that certain forms of suffering may have purposes humans cannot comprehend. Still others have questioned whether the existence of evil logically contradicts the existence of God in the first place.

Epicurus himself approached religion from a very different philosophical direction. He believed that the gods, if they exist, are not concerned with rewarding or punishing human beings. Fear of divine punishment and fear of death, in his view, were among the major sources of human anxiety.

More quotes by Epicurus

“Death is nothing to us.”

“Of all the means which wisdom acquires to ensure happiness throughout the whole of life, by far the most important is friendship.”

“He who is not satisfied with a little, is satisfied with nothing.”

“The wealth required by nature is limited and is easy to procure; but the wealth required by vain ideals extends to infinity.”

“It is impossible to live a pleasant life without living wisely and well and justly, and it is impossible to live wisely and well and justly without living pleasantly.”

Why Epicurus still matters today

Epicurus lived in a world vastly different from the modern one, yet many of his questions remain remarkably contemporary.

How much do we actually need to be happy? Why do humans fear death? Does wealth produce lasting satisfaction? Can friendship matter more than status? And perhaps most difficult of all: how should we understand suffering in a world that is supposed to be governed by a perfectly powerful and benevolent God?

His philosophy offered an answer to anxiety that was radically practical for its time. Rather than endlessly pursuing wealth, fame or power, Epicurus encouraged people to examine their desires, cultivate friendships, seek knowledge and free themselves from unnecessary fears.
