Yup, agreed. Likewise, concepts such as the taste of sweet, salt, sour; colors such as red, blue and yellow; behaviors such as aggressive, calm, afraid; emotions such as happy, angry, sad; evaluations such as beautiful, ugly, plain; All of these are from nature and nurture, they don't exist as mathematical laws or any sort of foundational aspect of how the universe works. It's all just subjective and arbitrary inventions we have created to categorize and make sense of what we observe. Yet they are all immensely important to us! Even though they don't have objective grounding. We base our entire societies, our ways of life, our ways of thinking, around these incredibly non-justified categories of things.
