Rules matter, and to be rules they need to be universal in form: always do this, never do that. But it is foolish to rule out in advance the possibility that an occasion might arise when normal rules just don't apply. Rules are not there to be broken, but sometimes break them we must.

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).

The border between the natural and the supernatural, religion and philosophy, may not always be clear. But there are lines and we should know and accept which side of it we are on.

Perhaps the biggest myth about cynicism is that it deepens with age. I think what really happens is that experience painfully rips away layers of scales from our eyes, and so we do indeed become more cynical about many of the things we naively accepted when younger.

Anger clearly has its proper place at work, which is neither wholly absent nor ever present. The manager who is an emotional blank is just as hard to work for as the volcanic boss, and both can do great harm by setting an unhelpful example for what kind of emotional expression is expected and accepted.

There are many things you shouldn't measure. Don't, for example, try to measure how much you love your wife!

Talking about creating truth tends to alarm people, because truth is meant to be 'just out there'. It doesn't take much thinking to appreciate that we sometimes change truths on the ground - sometimes just by words. A new law will change what is possible. I think - perhaps because the paradigm we follow tends to be scientific, and all about discovery - the creative element of truth is one upon which we don't focus so much attention. This is particularly so in anglophone philosophy, perhaps because we associate it too much with those 'pernicious' continental trends.
