Medical shock is a kind of failure of circulation. All over the body cells get too little oxygen, and in some cases, blood pools in places where it isn't needed. Sounds a lot like a liquidity crisis to me.
Wikipedia defines epistemology as "the branch of philosophy concerned with the nature and scope of knowledge".
Traditionally it has led to questions like whether we can really know
anything, and discussing the qualities of different kinds of knowledge
like logical or mathematical knowledge.
How much attention has
been paid, however, to the question "Who can I trust?" -- perhaps far and
away the most important epistemological question that anyone can ask.
