Does the problem of evil disprove the existence of God?

The problem of evil challenges the idea of an all-powerful and benevolent God. Philosophers argue that suffering may serve deeper metaphysical or moral purposes.

Is morality possible without God?

Some philosophers argue that morality arises from reason and human flourishing, while others believe it ultimately requires a transcendent foundation.

Can reason prove the existence of God?

Classical philosophers proposed arguments such as the cosmological and moral arguments to support belief in God, though critics debate whether these provide proof or philosophical justification.

Section 2: The Problem of Evil | The God Debate: Atheism vs. Theism

Moderator: Ibn Sīnā has argued that the existence of the universe itself points to a Necessary Existent. But what of the nature of this existence? It is a world filled with unimaginable suffering. This brings us to one of the most ancient and powerful challenges to theism: the problem of evil. We ask Mr. Hitchens to present the case.

Christopher Hitchens: Thank you. Let us, for the sake of argument, entertain the Sheikh's metaphysical abstraction—this "Necessary Existent." Let's grant it consciousness and call it God. What we are then confronted with is not a being worthy of worship, but a cosmic North Korean dictator—a celestial tyrant who has created a world that is a permanent, inescapable torture chamber. The argument is as simple as it is devastating. If God is omnipotent, he can prevent all suffering. If he is omnibenevolent, he would prevent all suffering. Suffering manifestly exists. Therefore, the being you call God is either not all-powerful, not all-good, or he simply does not exist. You cannot have it all ways.

Do not insult our intelligence with philosophical sophistry about free will. What freedom of will did the infant have who was born with Tay-Sachs disease? What choice did the villagers have who were swallowed by a tsunami? This is not moral evil; this is natural evil, built into the very fabric of the cosmos. Your God designed a food chain where creatures must tear each other to shreds to survive. He designed a planet with tectonic plates that shift and unleash hell upon the innocent. The religious response is to promise a fantasy compensation in a celestial afterlife. It is an odious attempt to justify the unjustifiable. The sheer, gratuitous, pointless scale of suffering in the world is the most powerful evidence against the existence of a loving God.

Al-Ghazālī: Mr. Hitchens's passion is undeniable, and his indignation at suffering is a testament to the moral compass (fiṭrah) that God himself has placed within the human heart. But this emotional recoil must not cloud rational judgment. You are looking at a master's tapestry from the wrong side, seeing only a chaotic mess of threads, and concluding the weaver is incompetent or malevolent.

First, you assume the purpose of this worldly existence (dunyā) is to be a paradise. This is incorrect. The Qur’ān explicitly states that this life is a place of trial. Hardship is the crucible that reveals the essence of a soul. Without difficulty, there can be no patience; without injustice, no struggle for justice; without fear, no courage. Virtues are meaningless abstractions in a world without trial.

Second, the great gift that elevates humanity is free will (ikhtiyār). For our choices to be meaningful, they must be chosen freely. Much of the evil you decry is the direct result of human beings misusing this sacred trust.

Third, you assume natural disasters are pointless. In the divine economy, nothing is without purpose. We see only the immediate pain; God sees the entire causal chain across time and its effect on countless souls.

Finally, and most crucially, your entire argument collapses because it assumes this world is the final and total reality. Your moral outrage at injustice is only coherent if you believe in an objective standard of justice. The very existence of un-recompensed suffering in this world is one of the most powerful rational arguments for the existence of the Hereafter (Ākhirah). Divine Justice is not negated by worldly suffering; it necessitates a final Day of Judgment where every atom of good and evil will be weighed. The problem of evil does not disprove God. It proves the necessity of a Day when the full tapestry will be revealed.
