If I'm a CEO and I say, 'Misogyny will not be tolerated', that's a more powerful statement than 'It is my sincere hope and our intention to eradicate misogyny from this company'. Sometimes saying things in that more categorical form, has a real function. Although, if you dig beneath it, it is actually one of J.L. Austin's illocutionary acts; you're trying to make something happen rather than describing something already happened. The fact that it has the grammatical form of a description is fine.

In my experience, those who make the biggest fuss about not spending much at Christmas are generally the ones who buy what they want and eat where they want 12 months a year.

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

Even if we can agree that some things are natural and some are not, what follows from this? The answer is: nothing. There is no factual reason to suppose that what is natural is good (or at least better) and what is unnatural is bad (or at least worse).

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.

On social networking sites, we may expose ourselves, but we choose to do so. We are in control and, often wrongly, we do not feel we are giving away tradable data.

When you do the right thing, but not to any particular person, we instinctively feel that we have earned some sort of pay back. Since no-one will do that for us, we opt for self-service reciprocation.
