economy

What is interesting about economics is economy, or relationships of exchange where every gain is also a loss. What's disappointing about economics is that it doesn't deal enough with annihilation, where there's pure loss, or where the one thing exits the relationship. Aren't suicide bombers totally irrelevant to economics?

This is one of the interesting ideas in the history of science to me, that there is not pure scientific progress involving increasingly accurate representations and understandings of the natural world. Instead, scientific progress necessarily involves some sort of loss of knowledge as well. Thanks Thomas Kuhn.

Isn't the same thing true about changes in belief? That there is no pure progress of understanding, but each change is a gain as well as a loss. Isn't the idea that scientific research is pure gain just as ridiculous as the idea that change in religious belief is pure loss? Or, to put this another way, aren't scientists who ignore scientific history just as ignorant as believers who only pay attention to religious origins and have no concept of changes in belief?
