“We need to let our children grow up to face the world armed with knowledge, with much more knowledge than we ourselves had at their age. It is scary, but the alternative is worse.”

Love is blind, as they say, and because love is blind, it often leads to tragedy: to conflicts in which one love is pitted against another love, and something has to give, with suffering guaranteed in any resolution.

You don’t get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better.

The mind is the effect, not the cause.

In the beginning, there were no reasons; there were only causes. Nothing had a purpose, nothing has so much as a function; there was no teleology in the world at all.

The only answer to the endless chains of why, why, why is that the alternatives died.

Churches have given us great treasures such as music and architecture. Whether that pays for the harm they have done is another matter.

Philosophers are never quite sure what they are talking about – about what the issues really are – and so often it takes them rather a long time to recognize that someone with a somewhat different approach (or destination, or starting point) is making a contribution.

There is a time for politeness and there is a time when you are obliged to be rude.

The secret of happiness is: Find something more important than you are and dedicate your life to it.

Now that mobile phones and the internet have altered the epistemic selective landscape in a revolutionary way, every religious organisation must scramble to evolve defences or become extinct.

If I know better than you know what I am up to, it is only because I spend more time with myself than you do.

We live in a world that is subjectively open. And we are designed by evolution to be “informavores”, epistemically hungry seekers of information, in an endless quest to improve our purchase on the world, the better to make decisions about our subjectively open future.

You can’t get through seminary and come out believing in God!

There are no forces on this planet more dangerous to all of us than the fanaticisms of fundamentalism.
