Love is indeed at root the product of the firings of neurons and release of hormones.

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.

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.

Yesterday's news feeds our fear that our neighbours are more likely than not to be bad eggs: benefit fraudsters, bogus asylum seekers, paedophiles or jihadist terrorists.

In the case of Donald Trump I think you've got to accept that a lot of what's going on in political discourse is based upon judgement. How the economy works - how people work - what will come to pass - what will not come to pass - what is possible - what is not possible. There is this whole modal dimension. There's a lot in politics that is making a judgement about what might be and can be and would be.
