Creativity means willing into being that which does not already exist. You may will it into being, i.e., create it, not from the fact that you don’t have it, in order to possess it or because you want it, but simply from the fact that it doesn’t exist. That is not a “lack” as an aspect about you, as creator, being in need of something you don’t have, but rather simply that it, the thing you create, objectively, doesn’t exist. That says absolutely nothing about your needs or lacks, but merely that objectively that “thing” doesn’t exist and objective reality would be better off if it does exist than if it does not.
That, again, says nothing about your personal needs, desires or wants. It can be an objectively grounded act of will, based upon an external objective determination that has nothing to do with you personally, neither your needs or wants, but merely for its own sake.
The existence of that created object may make absolutely no difference to you (fulfills no needs or wants) but that it makes a substantive difference to the objective “state of things.” That “state of things” need not have anything to do with you personally or your desires (needs or wants.).
Only a narcissist would claim that the state of objective reality must be tied essentially to their own needs and wants. Just as, I would claim, love in the sense of authentic agape does not will the good of the other out of some need or want of their own. The capacity to see “others” and “reality” as distinct from one’s own personal existence is necessary for reasoned judgement, objectivity, morality and love in the sense implicit in the Gospels.
This is precisely what I am claiming about objective morality and obligation in the sense of determining right and wrong as independent of wants and needs. Wants and needs might be considerations in the determination of right and wrong, but these are not the fundamental constituents. Otherwise, morality collapses into subjective wish fulfillment rather than teleological end.
This is, I would say the fundamental difference between our positions. I view “good” as a teleological end, you see it as merely the fulfillment of desires, wants or apparent needs. My claim is that these can be assessed and ordered - even disregarded - in terms of an objective good outside of our own current emotive state. That “good” cannot come from our internal mental or emotional state, but must come from the real nature of things.
