Freewill is an illusion. Our brains are only capable of 10 to the power of 70 million million 'actions' or 'thoughts'. Considering there are only 10 to the power of 80 atoms in the visible universe, that's a biggish number. But our minds appear to have limitless boundaries and this is what gives us the feeling we have freewill.

Infinity, on the other hand, is not limited. Well, it is limited - it's limited to being limitless; it can never be limited, the poor thing.

We live in a paradox - infinity can't exist, but then it can't not exist, either.

This is a great conversation stopper at dinner parties.

Next time your other half drags you to his/her friend's house to meet up with a bunch of friends, who have also dragged their unfortunate other-halves along, and the amount of glasses of Sainsburys Australian Shiraz Cabernet (£4.95 reduced from £7.95) consumed equals exactly the right amount to inspire a heated debate on something tediously political, like the occupation of Iraq, which threatens to drag on longer than the occupation itself, simply drop in the old infinity paradox idea at an appropriate point.

Restful silence is guaranteed. Unless your other-half's best mate happens to be going out with Aristotle.
