I am going to agree with Elayne even after I said I agree with what Don quoted, and this is an interesting application of the recent back and forth Elayne and I have been having. I think the statement is correct, as far as it goes, when limited to "in one's life" as if we are talking about one of us. That's a concrete application in which I think it is correct.
But Elayne is also extending the statement to its logical conclusions, and in doing so she is showing that a flat logical reading of it WOULD go to far.
This is back to our discussion of the interplay of logic and feeling/observation. Elayne is pointing out the issue from the position of making sure that the statement is logically consistent with the whole. She is correct in how the issue should be explained in the widest context. If we limit the discussion and state our limitations, then Don's view is acceptable.
We're making progress I think in seeing that we've got to articulate things in a "logically consistent" fashion while paying attention to both the "reasonable person" standard to come up with a "rule" or a "systematic explanation" and also the particular perspective of an individual focusing on what seems real to them locally.
I do not believe that Epicurus would say that his philosophy was anything less than rigorously logical and reasonable. We can achieve that aim, i think, and we HAVE to if we're going to be able to explain these issues to wider groups of people.
