I typed up a long post last week about anecdotes that I was going to make a separate topic, but then I decided not to post it. Since this conversation has taken a turn to where I think it is relevant, I will post an excerpt:
Consider the difference (in the US court system anyway) between a criminal trial and a civil trial. To establish guilt in a criminal trial, the prosecution must prove guilt beyond a reasonable doubt. To convict the defendant, the entire jury must agree that it is unreasonable to believe that the defendant is not guilty.
The civil trial on the other hand, requires only that a preponderance of evidence supports the claim. The civil trial is determining what is more likely, even if there is not a strong level of certainty.
Scientific proof is like the criminal trial. We have to be able to prove that a new hypothesis is very likely to be true and well-supported by evidence. This tends to be the realm of binary true/false type of situations. The speed of light in a vacuum is approximately 300 m/s - We have a lot of evidence to support this - The claim is true, and any other claim about the speed of light is false.
However, our personal beliefs are more like the civil trial. Each of us can look at the evidence and decide that one explanation is more likely than another, even if we don't have enough evidence to call it 'scientific proof'. We maintain a certain level of doubt, but lean in one direction or another. We weigh each possibility and determine how likely it is that each is true. We may all come to different conclusions for different reasons. This is (or at least should be) the realm of the agnostic.
Let me first say I think you've made good sense.1). So what do we do with anecdotes? Obviously they do not fit into the 'scientific proof' category. I think most of us can agree on that. But what about the personal belief category - is it unreasonable to consider any anecdotes? Are they completely worthless? Should we dismiss piles and piles of anecdotes just because they are not scientific proof? It seems in terms of determining what one personally thinks is more likely, some anecdotes should be considered - it is part of discovering the preponderance of evidence.
Here's the overarching problem with anecdotes. How can they be tested? Are they completely worthless? Maybe not. It is difficult to determine if there is value in something that can't be examined firsthand and reexamined thereafter
As for their value in personal truth they are of great value. If it stopped there there would not be this offhanded dismissal of their use. But people do use then in a way that reaches well beyond power of the anecdote itself to state what is objectively true. Do you follow?
It's natural to have a personal belief. I can say for certain skeptics have that too. However no one should claim their belief is objectively true.I think the trend in the skeptic community is to eliminate the 'personal belief' category altogether by making the standard for 'personal belief' the same as the standard for 'scientific proof'. You could almost use this as the definition for the skeptic philosophy. Whether this is the right thing to do or not is subjective, and I don't presume to be able to objectively define this as better or worse than any other belief system.
I agree with the textbook thought.However, my personal feeling is that this approach is wise when we're talking about what should be written in a science textbook or taught in a science class. But in our personal lives? Most of human experience does not fit into the scientific proof category. If we eliminate the personal belief category altogether, I don't see how we can avoid losing some of what Joseph Campbell calls 'The feeling of being alive' that all human beings yearn for. Your life is your own personal anecdote, and it can be filled with magic if you allow it to be.
I'm going to look up this quote by Campbell before I comment. I want to understand precisely what is meant by it.
