Much is made in the history of human relations about the particular lineage of individuals. The study of human lineage is called genealogy. Are you related to royalty? Which nation or tribe do you descend from? What exterior appearance factor of your body indicates a certain lineage or background? What traits do you share with another group of people? So, for Individualism, how do these details in human lineage help us to define each individual?
Individualism does not believe that your lineage, or where you came from, has anything to do with who you are as a unique individual. This is not to deny that genetics can play a part for medical reasons or will affect your outward physical appearance. But again, Individualism is based on the mind defining someone, not the body, so what you physically look like does not matter.
Every human mind is unique. Yes, it is shaped by culture, learning, human relationships and even somewhat by genetics but every mind is as unique as every snowflake. No matter what your lineage or background, the unique mind has the capability of becoming whatever it decides to become. Who you really are is not controlled by other people or societal rules, it is decided by your mind.
If you are of royal ‘blood’ does this make you special? Of course not. Your blood does not make you anything. Even the acceptance of being ‘royal’ is accomplished by the mind buying into the false idea that royals are somewhat better human beings than others. They aren’t. They are as human as the rest of us.
The assumption needed for this way of thinking is one of free will. Those who believe that people are ‘determined’ (simply a action and reaction to their environment) may consider biology and environment very important for human definition. Those of us who believe in free will also believe in the inherent individuality of each human being based on their ability to change their future by their independent actions and thoughts.
Genealogy does not dictate who you are no matter who your ancestors were. Your mind controls who you are just as it decides your character and actions. We are all unique with virtually unlimited potential. That potential comes from the most powerful part of our bodies, our minds.
