Nature deals the cards without thought or care, and there is no point in blaming the dealer. All we can do is make the best of the hands we have been dealt.

I am very Aristotelian in approach - not in detail - so I always find I'm saying things that get people frustrated like 'It's a matter of balance and judgement'. To a lot of philosophers these are terrible words because they're admitting of vagueness and uncertainty. The more I've done philosophy, the more I've become convinced that that is the way it is.

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.

A lot of religious belief - even the majority - involves making factual claims about the world which do come into conflict with science and history. For Christians, a test of this is the Empty Tomb. I ask Christians: 'are you saying that it does not matter - as a matter of fact - whether or not Christ's tomb was empty and that he was resurrected?' At that point, I find that, to a lot of them, it really does matter, despite all the fine talk about not wanting to confuse science and history with religion.

Justice can only be dispensed when you have all the facts in front of you.

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.

If there is an art of living, it is not something that can be taught timelessly. We have lessons to learn from Aristotle et al, for sure, but not if we simply uproot them from their epoch and stamp them into 21st-century soil.
