Why can't we summon the ingenuity and courage of the generations that came before us? The dinosaurs never saw that asteroid coming. What's our excuse?

We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.

Ignorance is a virus. Once it starts spreading it can only be cured by reason. For the sake of humanity, we must be that cure.

To assert that the universe has a purpose implies the universe has intent. And intent implies a desired outcome. But who would do the desiring? And what would a desired outcome be? That carbon-based life is inevitable? Or that sentient primates are life's neurological pinnacle? Are answers to these questions even possible without expressing a profound bias of human sentiment? Of course humans were not around to ask these questions for 99.9999% of cosmic history. So if the purpose of the universe was to create humans then the cosmos was embarrassingly inefficient about it.

In the end, it's the people who are curious who change the world.

I know of no time in human history where ignorance was better than knowledge.

The good thing about science is that it's true whether or not you believe in it.

It's better to understand something than to memorize something.

One of the biggest problems with the world today is that we have large groups of people who will accept whatever they hear on the grapevine, just because it suits their worldview—not because it is actually true or because they have evidence to support it. The really striking thing is that it would not take much effort to establish validity in most of these cases… but people prefer reassurance to research.

God is an ever receding pocket of scientific ignorance.
