It also gets never old to tell that this quote is most likely not from Socrates. But you know that already, don't you?

What we know from Socrates, this doesn't sound like something he would have said.

Although, having done no writings of his own, we have two main sources for his life.

But then again, Plato often put his own words into Socrates' mouth and this is something Plato could have said. :-)

Thank you. I didn't know we know the actual source.

I only knew of some leads back to the 50s or 60s.

Plus there is "professional speech" vs off the cuff. "Please pass the salt. - Barrack Obama" would probably technically be an accurate quote even if it wasn't documented.

There were accounts of cringeworthy even for the day dressing up in a dirty short cloak in immitation of Spartans.

Except this is a made up quote.

Look up the Hagakure, even there's a part about how "the youth of today" is lacking basic discipline etc.
