Is genetic superiority a guarantee of happy life?Please explain your reasonsing.
There are many factors that have to converge in order to find happiness. Genetic superiority would not be the sole factor in determining it. At the same time, I would also suggest that the notion of genetic superiority is a bit vague. At its best, genetic superiority might mean to avoid familial health conditions. Yet, there could be other factors, outside of genetics, that could cause such conditions, whereby genetic predisposition might not guarantee complete absolution. At its worst, the term "genetic superiority" has been the pretense for some of the worst of human actions. Given the fact that it is not an absolute guarantee, I would have to say that genetic superiority is not definitive in the realm of human happiness.
I think that the first thing you have to do to answer this is to figure out what you mean by genetic superiority. We do not really know for sure even if intelligence is passed down genetically. We surely do not know if the ability to get along well with others or to persuade others (like a salesperson or a lawyer would need) are are passed down genetically.
Even if they were, I would think that superior talent would not be a guarantee of a happy life. You could be superior and yet be unhappy because no one loves you, for example. Or you could have superior talent but be lazy and not get anywhere in life.
Some components of happiness may be genetic but certainly not all. A person could have been born to two, incredibly intelligent parents but perhaps they were not loving, nurturing parents. So you need to ask yourself what this child is learning as he or she grows up. A child like this may be predisposed to certain genetic factors but happiness is a learned behavior. As children we learn how to be happy by modeling behavior we see from those adults who surround us. I believe that this may be the most important factor in determining how happy a person will be.
