Why thank you for your kind offer!
Minchin is obviously a talented guy but also one of contradictions. He starts out by telling you authoritatively and absolutely that there is no meaning to anything.
Tim is not the Messiah, he's just a guy, with opinions. I happen to agree with him on meaning. Ultimately there is no meaning to anything in the long term. But humans are of the short term (both as individuals and as a species).
This he repeats several times throughout his talk and recommends the works of some of his favorite people (all atheists of course).
How dare he recommend the work of people he liked the work of.
Shakespeare and Dickens were atheists? Cool.
Then in the midst of his 10 tips for living he says to always be examining yourself for biases. (! except for Tim's of course! )
It was actually 9 things he'd learnt from his life. Now you might know better than Tim what he learned from life - but I'm going to give him the benefit of doubt on that one.
Tim actually says 'This is my opinion, at this point in time'. His whole point was that he does take his opinions out the back and beat them with a cricket bat.
Also, 'Be a teacher and spread your ideas' (presumably as long as you agree with his premise of meaninglessness).
Actually he says spray your knowledge. And you're arguing on the basis of your presumption, which is kind of masturbatory. Consider the audience he was addressing this to, young 20 something graduates. Having said how lucky they were to even be in the situation they were I think I'm happy for him to encourage them to share their good fortune. At no point does he set down strictures for what they should share.
Then he wraps it up by saying not to define yourself by the things you oppose. (again, unless you oppose finding any meaning in life for which opposition is mandatory).
Again you are straw manning - he offered the 'don't define yourself' by what you oppose BECAUSE he found himself doing it and was not convinced it was a good thing. And at no point did he say 'you' can't find meaning in life, only that you won't, and that he is convinced there isn't one, and has not found that lack has prevented him from having an engaging life, particularly if you define yourself by what you love.
Sorry Tim, I'm not buying.
And this is the keystone to ennuically obvious conclusion you came to.
He isn't selling anything. He's telling you his opinion, at this point in time. With some funny jokes thrown in. It's advice with a decidedly jocular, quasi-intellectual spin. Take it or leave it. He clearly had thought about a lot of this stuff a lot more than you thought about your dismissal of it.
He never dictates what what your opinions should be, what you have to believe, or how he will punish you if you don't. BECAUSE IF HE DID HE WOULD BE A ******* RELIGION.
