Our society is falling back increasingly on rampant consumerism and self-promoting social media as a way for people to feel that their lives matter - self-centered means of numbing the questions of mattering. Culture has relapsed back into the self-aggrandizing, glorifying answers that the Athenians had presumed, which had Socrates railing against them until he got so annoying that they killed him.

Paraphrasing Plato's Republic: "Only people who have allowed themselves to be reformed by reality have it in themselves to reform their polis for the better."

So dogma, doctrine, unexamined assumptions, that's what it is to be sharing that, the hippies shadow, no way of grounding it to reality. It's where we're just cut off from reality unless we can argue, we can substantiate, we can justify, we can convince each other.

In fact, the answers that religion, as we have come to know it, provides to the question of human worth have played so dominant a role in the preceding centuries that believers often cannot conceive how non-believers can muster sufficient commitment to their own lives to get out of bed each morning, let alone the ethical wherewithal to regard others as deserving of moral regard. Once one "comes out" as an atheist, these are the inquisitions to which one is often subjected.

Everybody is struggling to refine their views in opposition to the other people. And that's one of the most important things that philosophy actually has to teach us that you have to air your views and bring them to the table with people - with whom you disagree very much.

When the first people started to argue against slavery, for example, this was a new idea. If you crowd-source, you'd never come up with this. And so the - exactly the kind of progress we've made couldn't be made if we depend it on crowd-sourcing.

Plato dramatically puts the detachment of the philosopher from his time this way: to philosophize is to prepare to die.
