Right and wrong are not simply matters of evolutionary impacts and what is natural.

Atheists should point out that life without God can be meaningful, moral and happy.

Philosophy has to be enquiring; it can take nothing on faith, and its methods are based not on the blind acceptance of authority, but on establishing truths by reason and argument.

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.
