This is typical for modern western thinking, which is characterized by a masculine way of reasoning, a mode of thought which is highly developed these days. It causes extremely refined sciences, but in a certain respect it is very short-sighted. The notion 'equality' namely doesn't concern a quantity but a value. So equality means that there are equal values. Reality however doesn't know anything of values.
All phenomena exist just like that and by consequence they are totally 'worthless'.
One day man will be full-grown and then he will be familiar with the fact that reality is without any value. Awareness of this fact makes equality to a significant characteristic of future mankind.
