nice guys finish first
nice guys finish last...american biologist Garrett Hardin used it to summarise the message of what may  be called 'sociobiology' or 'selfish genery'. it is easy to see its aptness. if we translate the colloquial meaning of 'nice guy' into the darwinian equivalent a nice guy is an individual that assists other members of its species, at its own expense, to pass their genes onto the next generation. nice guys, then, seem bound to decrease in numbers: niceness dies a darwinian death.
