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.

Free Will Under the Microscope | The Illusion of Choice?

Sartre: Very well. Let us move to the heart of the matter. I do not merely claim that consciousness exists. I claim that to be conscious is to be free — radically, inescapably, and terrifyingly free. The human being is the being for whom existence precedes essence. A knife has an essence — a function — determined before it exists. A human being arrives first, and determines its own essence through its choices. This is not a comforting thesis. It means there are no excuses. No nature, no history, no circumstance relieves you of the burden of choosing who you are. We are, as I wrote, condemned to be free.

Dennett: I find the phrase "condemned to be free" romantically compelling and philosophically misleading. Consider the Libet experiments. When a subject spontaneously flicks their wrist, the brain shows preparatory activity — the "readiness potential" — up to half a second before the subject reports the conscious intention to move. The decision appears to precede awareness of the decision. Does this not suggest that your radical freedom is, at best, a story told after the fact?

Sartre: It suggests nothing of the kind. You are confusing the neurological preconditions of an action with its meaning. The readiness potential measures electrical changes in the cortex. It says nothing about what the subject is doing — about the project they are enacting, the situation they are responding to, the future they are choosing toward. My freedom is not located in a gap in the causal chain. It is located in the relationship between consciousness and its situation — in the capacity of the for-itself, the pour-soi, to negate what is given, to take a stand on its own being. That is not a physical event. It is an ontological structure.

Dennett: I agree — and this is where I think we are closer than you suppose. I am not a hard determinist. I do not say free will is an illusion in the sense that our deliberations are irrelevant. My position is compatibilism: the kind of free will worth wanting is fully compatible with determinism. What matters is whether your action flows from your own deliberative processes — your values, your reasoning, your character — rather than from coercion or compulsion. The fact that this process is implemented in neurons does not make it less yours. You wrote using your hand. The hand is made of atoms. Does that make the writing not yours?

Sartre: The comparison flatters your position. The hand does not deliberate. I deliberate. And deliberation — genuine deliberation — is not a process that follows from prior causes like water flowing downhill. It is a confrontation with nothingness: with the fact that the future is genuinely open, that I could do otherwise, that no fact about me — not my history, not my character, not my neurons — determines what I will choose. This is not poetry. This is the phenomenology of decision. Every person who has faced a genuine moral choice knows what I am describing. The pause before the act. The weight. The vertigo of freedom.

Dennett: I know what you are describing. I call it the phenomenology of deliberation — and I do not deny it. I deny only that it requires the metaphysical apparatus you build around it. The vertigo you describe is real. It arises because the outcome of deliberation is genuinely uncertain — not because the brain is indeterministic, but because deliberation is a process in which the outcome has not yet been fixed. You are not standing outside causality. You are causality — the most sophisticated part of it. And that is enough to ground responsibility, dignity, and the weight you rightly assign to choice.
