Untested assumptions and lazy habits of thought can be shown up, once put in a spotlight of a different hue.

The very act of questioning whether you exist proves you do, because you must be there for the doubt to be entertained in the first place.

No one who has understood even a fraction of what science has told us about the universe can fail to be in awe of both the cosmos and of science.

True virtue would never liken its rewards to points on a loyalty card, not because it is its own reward, but because it is not something we should practice to accrue future benefits.

If I hammer my own thumb while doing some DIY, it's not nice, but it's not the end of the world. To care obsessively about similar levels of discomfort in animals seems to be a case of mistaken moral priorities.

Science works because the phenomenon being described can be relied on to remain the same. Even in quantum physics, where phenomena are changed by observation, the way in which observation interferes is regular and falls within a limited range of possibilities. Human culture, however, has the nasty habit of never staying the same for very long.
