“Out of all the things in the world that we try to explain, human behaviour is surely the one that we work hardest at, and the one with which we find most difficulty. There is an obvious problem in the case of other people’s behaviour, because so much of the evidence is unavailable to us. All we know of how they see the world, and what they feel about it, is what they are both able to articulate and choose to reveal, and what we can infer from their actions and appearances. But this inference, and even our understanding of what they tell us, depend upon relating the evidence to our own way of seeing the world, our own feelings, and our own behaviour.” — Michael Frayn, The Human Touch
And we’re not all that clear on those last three, I might add.
