"To answer bluntly, altruism is the irrational side of man. Man's mind can override what is best for personal survival under certain circumstances."
> No its not. Altruism evolved for a purpose and was genetically selected for because it benefits THE INDIVIDUAL. You need to read up on game theory, particularly evolutionary game theory. If I am part of a social structure, and ALL hominids have evolved within highly complex social structures, I display altruism towards my conspecifics simply because this altruism will be reciprocated and hence ultimately promote my OWN survival and the passing on of my DNA. Virtually all anthropological studies have confirmed that within primate social structures, "selfish" behaviour invariably leads to expulsion from the group. What is "best" for personal survival is being accepted and PROTECTED by your conspecifics within a social group. Excessive altruism can of course be maladaptive, if there is no reciprocation. However, given the common evolutionary history shared by hominids, some form of reciprocity is virtually guaranteed. Those incapable of altruism are usually weeded out as "sociopaths".
"I don't see altruism as a benefit at all!"
>See above, and read Dawkins "The Selfish Gene".
"So many things humans do because they think (and often don't do it skillfully!) illogically and form values based on misperceptions."
Yup, and this is just as likely to lead to maladaptive "selfish" behaviours as to maladaptive "altruistic" behaviours.
"Human emotions stem from the value-setting that goes on as experiences pass through the mind. As I've stated elsewhere: what we don't "consciously" accept as a well-reasoned evaluation and considered opinion causes a default. The default is value-setting that is ill-considered and illogical. It takes many forms, but chiefly; rumor, innuendo, superstition, fable, hearsay, family prejudice, etc."
> A gross over-generalization of humanity. You've been reading too much Ayn Rand, apparently, LOL...Obviously some people are susceptible to this, but you are using far too broad a brush. In addition, "human emotions" do not "stem" from "value-setting". Values stem from emotional conditioning.
"Humanity in groups can be quite irrational in behavior. Poor thinking can infect insular groups."
> Yes of course. However, social isolation is equally unhealthy. Have you heard stories of prisoners in solitary confinement ? Insanity and irrationality quickly develops in the absence of other individuals to serve as psychological and emotional "sounding boards".
" A grenade lands in a foxhole and one person throws their body over it to absorb the damage rather than everybody dying. This is logical and demonstrates how the attrition redounds to the benefit of one's fellows (valued by friendship and comraderie.)"
Yes, OK. But how is this altruism "logical" while others are not? What exactly is the "type" of altruism you find to be irrational? (cue drum roll for Ayn Rand cut & paste....lol )
"Secondly, a parent who must give up something precious to enable their offspring to benefit can be logical too. Parents attach considerable value to their children because the next generation carries on the values of the previous one."
> Well, not really. Parents attach considerable value to their children because they carry their DNA and genetic heritage forward to further generations, but I did enjoy your sentimentality in that statement!
