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.

For most people their ideal life involves an intimate relationship with another person; one which often has a sexual basis. But there's no logic about it; why shouldn't people choose to live together with someone they just like? 'Of course' if we were too unquestioning about it, and we said 'well, that person has got to be someone of the opposite sex, and it's got to be for life, and divorce is terrible', then we're stuck. But if you don't recognize the importance that kind of bond has for human beings - you can't really understand what is needed to live a good life.

Seek first what is true and of value, and then whatever happiness follows will be of the appropriate quantity and, more importantly, quality.

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.

If there's one thing that makes me cynical, it's optimists. They are just far too cynical about cynicism. If only they could see that cynics can be happy, constructive, even fun to hang out with, they might learn a thing or two.

The optimist underestimates how difficult it is to achieve real change, believing that anything is possible and it's possible now. Only by confronting head-on the reality that all progress is going to be obstructed by vested interests and corrupted by human venality can we create realistic programmes that actually have a chance of success.

From time to time, it is worth wandering around the fuzzy border regions of what you do, if only to remind yourself that no human activity is an island.
