This is a philosophical statement. It is intended to spark thinking and examining.
There is little inherent in what we do, how we live, who we think we are, our cultural norms, or the way we’ve designed our living on this planet.
Put another way, often things we feel are innately true are not exactly that.
(Consider, as a simple example, the colours pink and blue; one for girls, one for boys. Normal and sound. Even if we rail against it, it is often not so much to rail against it but mostly to rail against the scorn for a child choosing to go against the grain.
Yet, prior to the 1940s, pink was the colour promoted for boys, and blue was the colour for girls. That was the correct natural order, with pink (close to red), a strong colour, and hence better for boys, and blue, more delicate, for girls.
And prior the first world war, children of either sex were clothed in white frilly dresses until age 6 or 7, the age of their first haircut. Only then would boys be switched to pants.
Something that now seems so inherent and natural has not even been a thing for a century.)
