Rationality/Evolution Theory: does not explain why physical state r causes movement b - (if R is the corresponding rational reason and B the rational action) - Nozick: if R is not a rational reason there would be no organism that would be selected for it. - ((s) Because irrational organisms are not selected, one could not recognize rational behavior particularly and describe it.
Nozick: nevertheless: if r would not be rational, the organism would not have been selected - "downward causation" - so after all: rationality in the world.
Theory of evolution/Nozick: seems to eliminate values and evaluative facts - even if action is related to belief, it is not in connection with judgmental facts.
instead, "invisible hand, blind mechanism" - Ethical behavior could be inherit - "Punchline: that does not undermine the role of ethical facts. - Explanation: individual behavior is not - "explained blind" - solution: in addition one needs truth for explanation.
Moral belief must ultimately be in connection with its truth - but that does not show that from a successful explanation of the invisible hand (blind explanation) could not follow that there may be no connection with accuracy._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
