Yes it is, and that was part of my point. If I say that a purple cow exists, I am telling the truth, because I am an Idealist, and thus anything that I can concieve of in my mind exists. However, I cannot show this to exist.

How do you show anything to exists? I hardly think that an idealists is going to define their belief based on whether they can show it to someone else. This definition just begs the question and pushes the distinction of what matter is off into phrases like "can be shown". Again, this may "effectively" be what their belief entails but it is not the definition of their belief. If you read Heusdens definitions you will begin to see what I'm talking about.
I'll try to do that tomorrow (have very little time left now).
Anyway, if I can point at something, then I can show that it exists. If I can mathematically describe something, then I have shown that it exists. What is lacking here?
You are not understanding. Heusdens is not making any claims here. He has only provided the accepted philosophical definition of materialism. You can't intuit the truth of definitions because they are invented by humans for the purpose of communication. So if this proper and MUCH more useful definition is used then according to that definition "love" is a non-material thing. It has nothing to do with Heusdens.
No, a definition is not just based on human consensus, the definition has existed as long as that which it defines, it is the
word that was later assigned by humans. Thus, if I say (for example) "theory", I have used a word to describe the existent-independent-of-a-word-to-desribe-it thing that can be described as an hypothesis with a large measure of evidence to support it.
I don't understand the point. My point is that there can be distinctive holistic effects of parts participating in a complex process. For the purposes of making the distinctions in the philosophical debate, "love" is a word used to describe the non-material holistic effect of "whatever process you think causes it." We're not proclaiming truths here, we're only trying to assign words to useful concepts.
Fine, but "love" is a word, used to describe something that was originally believed to be non-physical (and emotion was not always considered a physical process, and, apparently, still isn't considered that by some people), so we are re-defining it, using scientific consensus as our basis.
Couldn't agree more. But some people are unwilling to concede that their definitions are not consistent with the accepted meanings and refuse to pick up a 101 textbook and educate themselves.
True, and I think
all of us (excluding no one) have been guilty of this from time to time.
