newbitech, what about the opportunity cost concept? That says nothing about quantifiable values. For example, "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." Clearly you can't put a price on sacrificing your own child to save the world...but clearly there is the opportunity cost concept.
Just doing a little more reading to understand how the idea you bring might relate to self-sacrifice. Here is another blurb from the source collection you mentioned.
Opportunity costs are not always measured in monetary units or being able to produce one good over another. The opportunity cost can also be unknown, or spawn a series of infinite sub opportunity costs. For instance, an individual could choose not to ask a girl out on a date, in an attempt to make her more interested by playing hard to get, but the opportunity cost could be that they get completely ignored, which could lead to other opportunity costs.
I am not sure how useful the concept is in understanding WHY people do what they do when we are unable to KNOW the opportunity cost or when calculating the opportunity cost is like asking a computer to solve pI with no constraints.
So in trying to understand things like WHY would Ron Paul give up a life of say being a highly successful FULL TIME doctor, which certainly put more gold in his pocket, as opposed to the highly UNLIKELY "cause" he is attempting, well how do you figure out the opportunity cost? Did he one day sit down and think, hmmm what is going to be better for my bottom line?
I understand the desire to put every person's action in the context of economic law. I also believe that economic law doesn't really handle what I would consider non economic decisions. We do not always sit around considering the economic consequences of our actions. These economic laws may describe what is going on, but they do not really give a WHY. I appreciate the description and the context. Economic certainly gives me a baseline to compare. Humans are not robots or calculators though. I understand that the Austrian Economic Model is different than Keynesian or Chicago etc etc. But they are still economic models.
I am not saying economics aren't useful, but when trying to describe actions of other humans that are confounding and uncover apparent paradox in what we understand, I think it's useful to bring in other sources of knowledge and wisdom. Thinking outside the box so to speak.
I don't view these as competing ideas, but rather complimentary.
Here is another excerpt from the source I cited. I think it helps explain some of the paradox that economics uncovers. Particularly, the paradox that comes up when we cannot know the opportunity cost, or the calculation of opportunity cost must be "rounded up" because of the infinite spawns.
What I have set myself to make plain in this series of graded examples is simply this: self-sacrifice is not something exceptional, something occurring at crises of our lives, something for which we need perpetually to be preparing ourselves, so that when the great occasion comes we may be ready to lay ourselves upon its altar. Such romanticism distorts and obscures. Self-sacrifice is an everyday affair. By it we live. It is the very air of our moral lungs. Without it society could not go on for an hour. And that is precisely why we reverence it so–not for its rarity, but for its importance. Nothing else, I suppose, so instantly calls on the beholder for a bowing of the head. Even a slight exhibit of it sends through the sensitive observer a thrill of reverent abasement. Other acts we may admire; others we may envy; this we adore.
So basically, there is no opportunity cost in self sacrifice and their is infinite opportunity cost in self sacrifice. This principle stands on it's own and must be explained and understood on it's own. The idea of self sacrifice picks up where other ideas leave off or get stuck in loops. The reason I believe this happens is because as individuals we are unable to penetrate the individual "shell" or "sphere". It is the base unit, and in relationships self sacrifice is the bonding agent.
Another analogy I just thought of. Think about building some complex product. A house or a car. These items are made up of hundreds if not thousands of parts. Think of the nail or the screw. Without these parts, we could never put the house or the car together. Yet, each nail and each screw are "worth" what? We could say that those nails and screws are priceless, because without them, you'd not build the house or the car. Of course when looking at this from the perspective of opportunity cost, they are extremely cheap because these essential items are plentiful and abundant.
So you have the economic "value" of these nails, but you also understand that removing the "glue" that holds all the parts together make the entire idea of a house or a car fall completely apart.
This is what self sacrifice is for relationships. Yet, we don't look at a nail or a screw and say.. wow that is such an awesome thing. What a site to behold. But when we see someone like Ron Paul, or Jesus Christ, the furthest thing from our minds is the opportunity cost as we understand just how amazing their actions are for the "good" of the human species.
