George Soros, 'failed philosopher'

reading Soros' latest book, "The New Paradigm for Financial Markets"

"If I understand it correctly, the theory asserts that market participants, in pursuing their self-interest, base their decisions on the assumption that the other participants will do the same. This sounds reasonable, but it is not, because participants act not on the basis of their best interests but on their perception of their best interests, and the two are not identical." (p56)
