Christopher Hitchens on The fine-tuning argument
Hitchens argued that the universe's vastness and hostility to life make fine-tuning for human benefit absurd.
Hitchens engaged the fine-tuning argument primarily through rhetoric rather than physics, but his rhetorical instincts were sharp. His favourite response was to note the sheer scale of cosmic waste. If the universe was fine-tuned for life, the designer made 99.9999% of it lethal vacuum, filled it with galaxies that will never be visited, and placed life on a fragile planet orbiting a mediocre star in an unremarkable galaxy. This is fine-tuning?
He also pointed to the timeline. The universe existed for approximately 13.8 billion years before human beings appeared. If humanity was the point, the designer spent 99.998% of cosmic history on the prelude. The disproportion between the apparent purpose (human life) and the means (a universe overwhelmingly hostile to it) struck Hitchens as absurd rather than awe-inspiring.
Hitchens's deeper objection was theological rather than scientific. Even granting fine-tuning, the argument establishes at most a deistic designer, not the personal God of Christianity. The jump from 'the constants are calibrated' to 'Jesus rose from the dead' requires an entirely separate set of arguments, none of which fine-tuning supports.
“We are obliged to live in a universe that is 99.9 percent hostile to us, and that will eventually consume us entirely. Some fine-tuning.”
