{First, I’ll phrase it in some technical language, but then I’ll simplify later on.}
To judge J, at time t, something is valuable if its properties are perceived as matching the property-names that comprise the meaning of the thing-being-evaluated.
We learn meanings associated with specific words or concepts when we first learn the language, our native tongue. For purposes of logical analysis, the meaning is here seen as a set. …a set of predicates (property names.) If this set matches {even partially} the properties in the item (or person) being judged, prized, valued, assessed, then the judge (the one doing the evaluating) will tend to describe the item as “valuable” or as “having some value.”
To put it in plain simple everyday language, when the actual matches the ideal, there is value. [ The actual never has to touch the ideal, just correspond to it, in the mind of the valuer. Value is a matter of degree: to the extent x matches the picture you have for x’s in your mind, you will tend to call it: a good x. ]
If it has everything (it is supposed to have in the picture of the ideal concept of things of that kind) then the valuer is likely to call the item “good” or “a good one.” So, goodness is: being all there - under its concept. Exemplifying fully its concept makes something “good.”
I trust this has been helpful and is responsive to everyone who had an inquiry about this topic.
