Do we Share a Definition for the word “ideal”?

Related: A Proposal for a Simpler Solution To All These Difficult Observations and Problems

Perhaps this will be seen as spam and that I have broken a rule of propriety, but my previous discussion has already served its purpose and I think will continue to do so. I needed it as an open dialogue to get a general idea of what the implications of a stable metric for value would be (ie it would solve many otherwise difficult to solve problems).

In relation to such a unit of value, I would like to ask what is your definition of the word “ideal”. On the surface this question might seem empty, but I often observe with people that we don’t all share the same meaning for the word, and that the discrepancy is significant.

Do we have a shared meaning for this word?
