There is nothing called natural in itself. Any given repetitive behaviour is perceived as natural by its subject and by others. Therefore, is natural the synonym of repetition?
Rituals and habits are referred to as a second nature. Then, what is the first nature? Speaking of human nature, perhaps the first nature (the core human nature) is the ability to learn, to adapt, to repeat and to evolve. The Swiss philosopher Jean-Jacques Rousseau defines human nature as “perfectibility”, the capacity of becoming perfect.
This is the reason why breaking habits isn’t an easy task. It is shedding an “old nature”. The brain is a ritual machine, functioning with schemes and patterns followed by rewards if well repeated. Addiction is in this picture. To change habits, to shed the “old nature” requires thought changing and new habits.
Replace, repeat, reward!
