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.

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

I am only me for practical purposes.

Whatever your religious persuasion, if you believe that the universe is governed by benign forces, at some point you have to explain why there is so much suffering, misfortune and misery in the world.

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. Trump frightens a lot of people but there is a bizarre possible world in which it turns out as he's vindicated, though most of us think the evidence is against it.

When you try to translate any kind of real-life problem into a neat logical form, you're almost always simplifying it. We need a kind of blend - we need to use not just tools of logic, which are important and valuable - I'm not denying that, but also tools of judgement, and of inductive and abductive reasoning which can also inform.
