00:00:00.000 --> 00:00:09.040
[CLASSICAL MUSIC]
00:00:09.340 --> 00:00:29.020
[APPLAUSE AND CHEERS]
00:00:29.100 --> 00:00:32.300
Well, thank you all very much for coming to this.
00:00:32.300 --> 00:00:37.900
It's really shocking to me that you don't have anything better to do on a Tuesday night. [AUDIENCE LAUGHTER]
00:00:38.800 --> 00:00:40.960
No, but seriously, though, it is.
00:00:40.960 --> 00:00:52.240
I mean, it's very strange in some sense that there's so many of you here to listen to a sequence of lectures on the psychological significance of the Biblical stories.
00:00:52.320 --> 00:01:02.120
It's something I've wanted to do for a long time, but it still does surprise me that there's a ready audience for it.
00:01:03.220 --> 00:01:07.440
So that's good, so we'll see how it goes.
00:01:08.920 --> 00:01:11.280
I'll start with this because this is the right question.
00:01:11.280 --> 00:01:13.720
The right question is why bother doing this.
00:01:13.720 --> 00:01:16.380
And I don't mean why should I bother doing it.
