EVOLUTION AND SELF-INTEREST
Richard Dawkins argues that at its most fundamental level, the genetic level, life is self-interested.1 Genes do only one thing; they replicate themselves. These replicators reside in and are carried around by biological vehicles (trees, animals, humans, fungus, etc.). The resources that support these biological vehicles are finite, so the process of life has become a competition among genes to create vehicles that can successfully compete for limited resources and survive to pass on their genetic code. Dawkins coined the term ‘selfish gene’ to emphasize the single, focused object of a gene’s existence. What he means is that the sole purpose of a gene is to make copies of itself using the Darwinian selection process; very selfishly ignoring the consequences this pursuit may have on other living entities.
Self-interest is a requirement for survival. This does not mean, of course, that animals and humans cannot be altruistic sometimes, in certain activities.2 It does mean that no living entity can survive for long if it is only purely altruistic. On the other hand, survival is not necessarily jeopardized when an organism is purely self-interested. Altruism, in the absence of self-interest, is not evolutionarily stable in the biological world; it leads to extinction. It is for this reason that all extant life forms must be selfish. Humans, like all creatures, are self-interested; not because it is good to be selfish but because we would not be here if we were not.3
SURVIVAL
Self-interest is a powerful motivation because the basic concern for biological survival is the insufficiency of the resources that are required to maintain life. Organisms cannot survive when they cannot get enough air, water or food, or do not have adequate information and/or competence to discover and utilize the resources that are available in their environment.
