A child suffers only if it thinks it is missing something, if you bring it up to be a warrior, i. e. to be able to live even without water for several days, then it will suffer minimally… correct?
As Nietzsche once said, nihilism does not come up in the time of material misery (in such times people learn to control themselves) but in the times of the material wellbeing. Nihilism, the radical escape from suffering.
That is pretty much like saying everyone can become a functioning scientist.
Not all have the same mindset. You can push and the child may be able to cope maybe not. Are you an only child?
I think if the child sees you are not in contradiction with your own self it will accept your ideas even if you are not his parent.
As a medicine against decadence Polybius or Plutarch has advised: "the cause of the harm is evident: by avarice or cowardice the people, if they marry, will not bring up the children they ought to have. At most they bring up one or two. It is in this way that the scourge before it is noticed is rapidly developed. The remedy is in ourselves; we have but to change our morals.”
So, whatever you change, the upbringing or morals it has the same effect.
What is feminismus marasmus or marasmus feminismus as Nietzsche points it? As Vollgraff says, the upbringing of children and the creation of them requires the most effort/endeavor from the parents, or in other words it requires a woman who needs to be a housewife to take care about the children and to reduce the costs of the family. Now while women don’t want to have many children and while the few if they have them are brought up by someone else (the state) they make no effort in their lives at all and that makes them weak. That is the marasmus, or wilting.
