Ladysolly has just told me that my favourite phrase is "I don't know".
I can believe that. There's so much I don't know. There's so much that I even don't know abojt the existence of huge areas of human knowledge that I've never even heard of.
I've noticed that I don't know a lot more than most people. Other folks have some great areas of knowledge that I can't even understand how they can possibly know what they say they know, which makes me even more ignorant.
And I'm not ashamed to admit when I don't know something - admission of ignorance can be the first step towards enlightenment. After all, if you already know all about something, there's no incentive to find out more about it.
I don't know that there's a Tooth Fairy; nor do I know that there isn't. Isn't that an appalling degree of ignorance? And the same is true of the Easter Bunny, the Great Teapot, unicorns and gods. There's an immense number of gods that I don't know whether they exist or not, although I'm inclined to be sceptical about whether they could possibly all exist; surely most of them, and possibly all, don't exist. But I don't know.
Fortunately, many of the things I don't know, aren't important. Some of the thngs that I don't know, can be looked up in books or on the internet - for example, I can never remember the exact syntax of the perl substr function.
So I don't think my deep ignorance is important.
But I don't know.
