From Dennis:
Importance is the basis of all significance.
The search for deeper significance into life or the mind is only the search for prior or greater importance.
Significance is the consideration of both the nature of a purpose and its importance.
There can be no significance in the absence of importance.
The significance of a thing is simply the purpose plus its importance.
Life contains a near infinity of significances, and we are addressing all of them when we address the basic package.
When we say significance we say what do the things signify, what does it mean?
The word significance has the same root as the word signal. What are the signals it's sending us? What does it mean? So if we know what it means, then we know what its significance is. But its meaning is essentially its purpose, its function, that is its essential meaning. So we're down to function again.
So significance is purpose plus the importance, that's all. A thing might have many purposes and each purpose may have an importance but essentially when you take a significance apart you're taking apart postulates, you're taking apart intentions, purposes, and that's all. There's nothing else there.
