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.

Economics is uncertain because its fundamental subject matter is not money but human action. That's why economics is not the dismal science, it's no science at all.

There have been a number of philosophers who have reveled in the dismantling of truth. I think they did so with good ethical motives, and for good philosophical reasons. I can see the sense in what they were talking about; the idea that truth is often claimed by elites in order to further certain agendas. They crowd-out alternative perspectives - particularly those of the powerless. But the undermining of truth contributed - in the weird, indirect way that philosophy contributes to the culture - to a rejection of the idea of truth as having any kind of proper meaning at all.

Accepting that the world is full of uncertainty and ambiguity does not and should not stop people from being pretty sure about a lot of things.

Perhaps the biggest myth about cynicism is that it deepens with age. I think what really happens is that experience painfully rips away layers of scales from our eyes, and so we do indeed become more cynical about many of the things we naively accepted when younger.

The simplest and clearest motivation for taking animal welfare seriously is the recognition that pain is in and of itself a bad thing, and that to inflict significant amounts of it unnecessarily is wrong.

Heathens are unredeemed outcasts from heaven who roam the planet without hope of surviving the deaths of their bodies. They may have values but they are not secured by any divine source. Yet we embrace this because we think it represents the truth.
