I've noticed that in the discussion that has gone on in this string so far, much of the disagreement (or confusion) has resulted from semantic differences rather than from actual differences in opinion. Put simply, it is quite difficult to express ideas clearly if there are no clear and unique definitions for the terms used. To this end, I have tried to come up with (a start at) more concise (if somewhat arbitrary) definitions for some of the main terms used. These include:
1) selfish (adjective): striving to promote the welfare and advantage of ones-self, at the expense of one or more others. This may or may not include resorting to acts that are unethical, illegal or immoral. An act of this type requires some (overt or otherwise) component which is performed with the express purpose of disadvantaging one or more others. Theft, cheating and class discrimination are examples of this type of activity. [selfishness (noun), selfishly (adverb)]
2) self-interested (adj.): striving to promote the welfare and advantage of ones-self, while, at the same time performing no acts consciously calculated to disadvantage others. Working for a living is an example of this type of activity. (Getting the job may have been either self-interested or selfish, however the act of working itself can be considered self-interested.) [self-interest (noun)]
3) self-centered (adj.): an activity that includes both those that are selfish and self-interested.
4) self-aware (adj.): involving the state in which one is cognizant of the relationship of oneself to others. If this state does not exist, any resulting activity cannot be considered selfish or self-interested, only reflexive. Other than humans, only great apes and cetations (dolphins) appear to have any degree of this quality. [self-awareness (noun)]
5) instinctive (adj.): refers to actions, responses and activities that were acquired at birth.
6) conditioned (adj.): refers to actions, responses and activities that are learned.
a) externally-conditioned: imposed by outside influences, i.e. environmental.
b) self-conditioned: imposed on oneself, generally through practice.
c) introspectively-conditioned: formed as a result of ones' own deliberations.
7) reflexive (adj.): refers to actions that are performed automatically (without volition or conscious control), as result of some stimulus, and that require essentially no forethought. [reflex (noun)]
8) volitional (adj): refers to actions that require forethought and conscious control. [volition (noun), ]
The words given above, are an attempt to take the ambiguity out of the terminology by designating unique words for each activity or condition, and for each word to have a unique activity. This was just a rough-cut designation, so if more fitting terminology is found, it should be substituted.
I agree with the string initiator, that selfishness is our basic trait. It's our link to the animal kingdom and our past - - - our possession of the main characteristic that helped us survive via natural selection before we had achieved our present level of self-awareness and superior cognitive abilities which now allow us (if we so choose) to displace selfishness with a higher and more effective capability - - - but we overwhelmingly don't do so; because it's just too comfortable to remain in our old patterns.
Where I differ from some of the others apparently, is in three areas. First, I don't believe that we are 100 percent selfish. (Maybe 99% - - - who knows?) It is this small minority trait in us (we all have it, but most don't develop it) which has allowed us to (painfully) advance our civilization over the millennia, but we are essentially still just Cro-Magnon humans.
The second difference is the fact that I do not believe in "Determinism" , that our nature and environment control our future. I believe instead that, with slow painful steps, we can improve our civilization; never to reach perfection, but certainly we can make it a lot better. - - - On the other hand, I harbor no illusions. - - - Nothing is going to come easy. (Things could also get worse.)
The third difference stems from my belief that, despite our "advances" in civilization, we are not essentially different 'inside'. Our moral rules, Laws, etc. just serve to inhibit our animal tendencies in some areas. We are far from achieving the "Best of all possible worlds".
These are reasons that I find this string so informative and important. I think that this is an important subject, and one that deserves a discussion that is as comprehensive as possible. I hope that these (definitions) will help a bit.
