The result of this kind of influence is twofold: one is a skepticism and cynicism towards everything which is said or printed, while the other is a childish belief in anything that a person is told with authority. This combination of cynicism and naïveté is very typical of the modern individual. Its essential result is to discourage him from doing his own thinking and deciding.~ Erich Fromm from, https://www.artofmanliness.com/articles/erich-fromm-think-originally-in-the-modern-age/
Philosophical Skepticism, “is a family of philosophical views that question the possibility of knowledge.” (That’s a quote from the Wikipedia entry. If you want to go deeper, try the Standford Encyclopedia of Philosophy’s entry for Skepticism.)
As far as I understand it—your mileage may vary—Fromm, in that quote, wasn’t condemning philosophical skepticism. Rather, and I agree, let’s all condemn the little-s-skepticism; the naivete driven, disbelieve everything, skepticism that turns away from anything it doesn’t understand.
I prefer to turn towards just about anything I don’t yet understand. (See: “Oh. That’s interesting…”) I’m am frequently asking myself: “What is true, and how do I know it’s true?”
