The mark of a mature, psychologically healthy mind is indeed the ability to live with uncertainty and ambiguity, but only as much as there really is. Uncertainty is no virtue when the facts are clear, and ambiguity is mere obfuscation when more precise terms are applicable.

It may not have the virtuous ring of the golden rule, but the maxim "never say never" is one of the most important in ethics.

The only good reason to embrace a philosophical position is that you are convinced it is true or at least makes sense of the world better than the alternatives.

The reason Buddhism can be so naturalised is because, stripped of its supernatural elements, its core teachings can be giving a sound, secular philosophical interpretation. In other words, it becomes a religion acceptable to the contemporary, naturalistic mind only when it ceases to be a religion.

Metaphorical tone deafness is when people are unable to discern what is of value in something. I think I'm tone deaf to poetry, for instance. Despite having studied it into a second year of university, most of it just leaves me cold.

It's not leftovers that are wasteful, but those who either don't know what to do with them or can't be bothered.

People seem very arrogant when they say 'I'm right and you're wrong', but in practice we all believe we're right. We have a staggering arrogance in our own belief. That can be tempered by not being 100% certain; by being provisional. No matter what the debate is, very few people have the modesty to suspend judgement on a whole range of things; most intelligent people have an opinion and are expected to have an opinion by other people - but it always requires making a personal judgement that goes way-beyond your expertise. We do it all the time.
