History, just like everything else in Nature, is cyclical.
History, just like everything else in Nature, is cyclical.
The responses, ranging from political partisanship, ad hominem, to being offended by the choice of words, are certainly a sign of the times.
If anything, history goes the other way around. Fascism ("strong men") comes from good times, as a reaction. They create authoritarianism and discrimination ("bad times"), which slowly liberalizes and equalizes (gives rise to "weak men"). This makes situation better until another fascist takeover.
Anyway, the quoted saying is not about any specific ideology, that's just your own projection. Here's the cycle reformulated without any specific ideology:
Hard times create strong men: hardship breeds discipline
Strong men create good times: discipline breeds prosperity
Good times create weak men: prosperity breeds complacency
weak men create hard times: complacency leads to hardship
Fascists (and protofascist advocates of social darwinism) do think that! Whether they actually are or not "strong men" (what does it even mean?) is immaterial to that saying.
I disagree with the saying. Even your formulation. Hardship doesn't breed discipline, and prosperity doesn't lead to complacency. There are many disciplined people who have good and prosperous life, and also, why is being disciplined more important than good life? It's authoritarian and backwards.
For example, being homeless (hardship) doesn't make one disciplined. Most likely, it will make one into an alcoholic.
Hardship is horrible and we should universally reject it.
So is the idea that "history is cyclical". It's literally the bell curve meme, and you're in the middle x)
I don't believe it. Personally, I think spiritual weakness and religious corruption are more likely culprits -- and not necessarily the type of spirituality or religion that you might be thinking of.
Either way, "good times" is a dangerous place to put the blame. It relieves us of responsibility for our own catastrophes (it was the good times' fault), and it makes us suspicious of prosperity and happiness.
Good times are not evil. We don't need to shun them, provided we keep strengthening the better angels of our nature.
