My main problem with this is that there is a majority of people who do not fall under the pressure of society. I think it is unnatural to give in to neurosis, as it demonstrates a person's inability to adhere to their own reasoning. A form of natural selection, if you will, where the strong are those who can manage a reasonable social life, and the weak are those who cannot. If neurosis was a sign that morality is bad for man, isn't it also true that a fulfilled life is a sign that morality is good for man? Isn't the very fact that humans thrive today a sign that morality is an achievement and not madness? Neurosis is a sign of mental weakness, and that is why they have a much harder life. A fish with a bad fin may give up fins altogether, but that doesn't make fins a bad thing. Yes, perhaps having fins prevents the fish from having other experiences, but it is also an essential part of the fish, the one that allows it to survive more easily. And just as fish developed fins to swim, humans developed morality to coexist. This is why I believe that neurosis is not caused only by the moral pressures of society, but rather by the weakness of the individual.
