This is a topic where we can discuss what we mean by “objective” and by “subjective”.  It is not tied to anything specific.  We don’t have to reach a consensus.

Here are a couple of examples to illustrate the issues:

1. Is mathematics objective or subjective?  On the one hand, it is mostly a mental construct, so in some views that would make it subjective.  On the other hand, there is very strong agreement between mathematicians, and that seems to suggest that it is about as objective as anything could be.
2. If we assume Berkeley’s idealism (the world is nothing more than a mental construct derived from our perceptions), would that imply that everything is subjective and nothing is objective?  Or, since we seem to all refer to the same things (cats, trees, etc) should we say that those are objective even if only mental constructs.

Here’s some personal correspondence between Liz and me. I presume that she checks posts before allowing publication, so if this is inappropriate I claim innocence.

Dear Liz,

As you know, I have great respect for you, even admiration, but I suggest the following.

You wrote:

The reason I get exercised about ID is that I do think, in simple scientific terms, that it is fallacious. Not because there couldn’t have been an ID, nor because science demonstrates that there wasn’t/isn’t one, but because the inference is, IMO, fallacious.

I respond:

The reason I get exercised about the proposed creative power of the Darwinian mechanism of random errors filtered by natural selection is that I do think, in simple scientific terms, that it is fallacious. Not because this mechanism couldn’t possibly have produced all that it is credited with, but because evidence, logic, and simple probability calculations demonstrate that this proposition is fallacious.

Thus, it seems to me, we are separated by an immense chasm over which there is no bridge.

Let’s face it, the ID versus materialism debate has profound scientific, philosophical, theological, and even ethical implications, which is why passions run so high.

Someone is wrong and someone is right. I just want to know the truth.

The ‘here’ in the first para refers to Secular Cafe, from which this is reposted.

In a number of threads, here and in other places, I’ve seen discussions – sometimes more than a little vituperative – concerning the value or otherwise of anecdotal evidence.

To start with my current position on it before commenting further.

I think that anecdotal evidence is evidence, but with three little caveats.

It is often, IMV, poor evidence, it is sometimes evidence of something other than what the anecdote purports to be evidence of, and it is rather infrequently later confirmed by later observations which have physical rather than anecdotal evidence behind them.

Having got that out of the way, an in-exhaustive list to identify the sort of alleged phenomena in which anecdotal evidence raises its head, in no particular order but as they spring to mind, with a few exceptions which I am anxious to include.

Ghosts, the effectiveness of clairvoyance, the effectiveness of astrology, the effect (or otherwise) of the full moon on madness,  hospital admissions et al, sightings of monsters on various lakes, UFO sightings, alien abductions, the power of prayer, what may broadly be called religious or spiritual experiences, unusual and hard or impossible to replicate physical phenomena.

For all of these, and others, I’d see it as important to keep a few things in mind.
