I was just thinking how easy it is to take our habitual ideas for granted, especially when every one else takes the same view.
Here are some to get started.
1) How do I know what I want, when I haven’t yet got it? Not having it, I cannot have an accurate idea about it. How much of life is spent (wasted?) in this uncertainty?
2) How do I know when something is doing me good, if the benefit does not occur immediately? For example, I go to a doctor or other kind of healer, who prescribes a course of treatment, and warns me it may be weeks or months before I get better. So I do get better. But how do I know I would not have got better without the treatment? (I accept that in some cases I would probably know.)
In the same way, how can I know that my prayer works, or what God thinks, etc etc?
