Christopher Hitchens has a lot of quote-worthy material, but here are 20 of my personal favorites:

“What can be asserted without proof can be dismissed without proof.”

The only position that leaves me with no cognitive dissonance is atheism. It is not a creed. Death is certain, replacing both the siren-song of Paradise and the dread of Hell. Life on this earth, with all its mystery and beauty and pain, is then to be lived far more intensely: we stumble and get up, we are sad, confident, insecure, feel loneliness and joy and love. There is nothing more; but I want nothing more.

―The Portable Atheist

By trying to adjust to the findings that it once tried so viciously to ban and repress, religion has only succeeded in restating the same questions that undermined it in earlier epochs. What kind of designer or creator is so wasteful and capricious and approximate? What kind of designer or creator is so cruel and indifferent? And—most of all—what kind of designer or creator only chooses to “reveal” himself to semi-stupefied peasants in desert regions?

―The Portable Atheist

The person who is certain, and who claims divine warrant for his certainty, belongs now to the infancy of our species.

―God Is Not Great

What happens to the faith healer and the shaman when any poor citizen can see the full effect of drugs or surgeries, administered without ceremonies or mystifications? Roughly the same thing as happens to the rainmaker when the climatologist turns up, or to the diviner from the heavens when schoolteachers get hold of elementary telescopes.

―God Is Not Great

Religion looks forward to the destruction of the world…. Perhaps half aware that its unsupported arguments are not entirely persuasive, and perhaps uneasy about its own greedy accumulation of temporal power and wealth, religion has never ceased to proclaim the Apocalypse and the day of judgment.

―God Is Not Great

Religion comes from the period of human prehistory where nobody—not even the mighty Democritus who concluded that all matter was made from atoms—had the smallest idea what was going on. It comes from the bawling and fearful infancy of our species, and is a babyish attempt to meet our inescapable demand for knowledge (as well as for comfort, reassurance, and other infantile needs). Today the least educated of my children knows much more about the natural order than any of the founders of religion.

―God Is Not Great

The Bible may, indeed does, contain a warrant for trafficking in humans, for ethnic cleansing, for slavery, for bride-price, and for indiscriminate massacre, but we are not bound by any of it because it was put together by crude, uncultured human mammals.

―God Is Not Great

If god really wanted people to be free of [wicked thoughts], he should have taken more care to invent a different species.

―God Is Not Great

Is it too modern to notice that there is nothing [in the ten commandments] about the protection of children from cruelty, nothing about rape, nothing about slavery, and nothing about genocide? Or is it too exactingly “in context” to notice that some of these very offenses are about to be positively recommended?

―God Is Not Great

Religion has run out of justifications. Thanks to the telescope and the microscope, it no longer offers an explanation of anything important. Where once it used to be able, by its total command of a worldview, to prevent the emergence of rivals, it can now only impede and retard—or try to turn back—the measurable advances that we have made. Sometimes, true, it will artfully concede them. But this is to offer itself the choice between irrelevance and obstruction, impotence or outright reaction, and, given this choice, it is programmed to select the worse of the two. Meanwhile, confronted with undreamed-of vistas inside our own evolving cortex, in the farthest reaches of the known universe, and in proteins and acids which constitute our nature, religion offers either annihilation in the name of god, or else the false promise that if we take a knife to our foreskins, or pray in the right direction, or ingest pieces of wafer, we shall be “saved.”

―God Is Not Great

Human decency is not derived from religion. It precedes it.

―God Is Not Great

Our belief is not a belief. Our principles are not a faith. We do not rely solely upon science and reason, because these are necessary rather than sufficient factors, but we distrust anything that contradicts science or outrages reason. We may differ on many things, but what we respect is free inquiry, openmindedness, and the pursuit of ideas for their own sake.

―God Is Not Great

Religion is man-made. Even the men who made it cannot agree on what their prophets or redeemers or gurus actually said or did.

―God Is Not Great

If religious instruction were not allowed until the child had attained the age of reason, we would be living in a quite different world.

―God Is Not Great

I try to deny myself any illusions or delusions, and I think that this perhaps entitles me to try and deny the same to others, at least as long as they refuse to keep their fantasies to themselves.

―Hitch-22

Faith is the surrender of the mind; it’s the surrender of reason, it’s the surrender of the only thing that makes us different from other mammals. It’s our need to believe, and to surrender our skepticism and our reason, our yearning to discard that and put all our trust or faith in someone or something, that is the sinister thing to me. Of all the supposed virtues, faith must be the most overrated.

Name me an ethical statement made or an action performed by a believer that could not have been made or performed by a non-believer.

Take the risk of thinking for yourself, much more happiness, truth, beauty, and wisdom will come to you that way.
