Socrates said that money in itself is neither good nor bad. But what matters is the use that you make of it, he says. And whether that's good or bad depends on how you use it.

Whether that's a good thing or a bad thing is going to depend on the type of person they are. That becomes the core or centerpiece of stoic philosophy, basically. The subtext there is that most people initially will confuse the superficial or secondary goods with the goal of life
