Sayings for Cynics Book

Shocking! Ok, I dunno why this one is so shocking but it is. It gave me a pause and a lot of starts: most of this stuff is what we see across lots of self-help lit of the modern kind. All these ideas have been packaged and repackaged and resold as some sort of new wisdom even though people could have been benefitting from it since circa 1647.

I definitely could visualize it being written in 21st century. And, nope, it seems to be first issued in the 17th one. Huh.

In fact, I can't see how it could've been so, SO darn modern. Of course, part of it is no thanks to my edition. Obviously, this has been linguisically modernised to no end and that is part of the reason why the book comes across as a hoax (which it isn't).
Modern edition:
1.
Se ha llegado a la mayor complejidad, pero la suprema es formar un buen hombre. Para formar a un sabio de hoy se requiere más inteligencia que para siete de la antigüedad. Y para tratar con un sólo hombre de estos tiempos necesitamos más sapiencia que para tratar todo un pueblo de los pasados.
The not so modern edition:

1.
Todo está ya en su punto, y el ser persona en el mayor. Más se requiere hoi para un sabio que antiguamente para siete; y más es menester para tratar con un solo hombre en estos tiempos que con todo un pueblo en los passados.

Different in language. Not so very different in spirit. While reading the 2 books feels like reading an original novel and a fanfiction based upon its world, the ideas are roughly similar. Which does give one a pause: what, have people really been this similar all this time? This similar? Like, having same cognitive and interpersonal issues?

Today, we are big on how Generations X, Y, Z (whatever) are different from the ones that came before. But, are they really? Or maybe should we/they/whatever learn to read and improve our focus and work on our skillset and generally improve ourselves without making all these highbrow statements on how scrolling since childhood is having allegedly positive impact on someone's skills with anything?

An illuminating read, obviously. Who would've ever guessed that people haven't really changed since 16XXs?
