Court gender and the Aquarian assumption

I've noticed an assumption that most esoteric systems seem to take for granted.  It's so fundamental that it's hard to state and even harder to challenge, but one way of putting it might be that if things can be divided into a small number of categories, then those categories must be equal, balanced, and symmetrical. Equality, balance, and symmetry are taken as a description:  people assume that things in the world really are equal, balanced, and symmetrical by nature.  They're also taken as an prescription:  causing things to be equal, balanced, and symmetrical is assumed to be a desirable goal or even the primary goal of the entire system.  I'm going to call all of that the Aquarian assumption.  You're not allowed to challenge the Aquarian assumption.  You won't be told that you're not allowed to challenge it, because the assumption is so deeply engrained as to be unstated.  If you work within an esoteric system you may find it difficult to formulate the thought of a challenge to the Aquarian assumption; or even difficult to think of the Aquarian assumption itself existing because the possibility of it not existing is so alien.  Do fish believe in water?
