I have been called arrogant myself in my time, and hope to earn the title again, but to claim that I am privy to the secrets of the universe and its … - Christopher Hitchens

When Socrates was sentenced to death, for his philosophical investigations and his blasphemy for challenging the Gods of the city and he accepted his death. He did say "well, if we're lucky perhaps I'll be able to hold a conversation with other great thinkers and philosophers and doubters too", in other words that the discussion about what is good, what is beautiful, what is noble and what is pure and what is true can always go on. Why is that important, why would I like to do that? Because that is the only conversation worth having. And whether it goes on or not after I die, I don't know, but I do know that it is the conversation I want to have while I am still alive. Which means that for me, the offer of certainty, the offer of complete security, the offer of an impermeable faith that can't give way, is an offer of something not worth having. I want to live my life taking the risk all the time that I don't know anything like enough yet. That I haven't understood enough, that I can't know enough, that I'm always hungrily operating on the margins of a potentially great harvest of future knowledge and wisdom. I wouldn't have it any other way. And I urge you to look at those of you that tell you (at your age) that that you are dead until you believe as they do. (What a terrible thing to be telling to children.) And that you can only live by accepting an absolute authority. Don't think of that as a gift, think of it as a poison chalice. Push it aside no matter how tempting it is. Take the risk of thinking for yourself. Much more happiness, truth, beauty and wisdom will come to you that way.

Hardest of all, as one becomes older, is to accept that sapient remarks can be drawn from the most unwelcome or seemingly improbable sources, and that the apparently more trustworthy sources can lead one astray.

You have to choose your future regrets.
