The Seven Hermetic Principles

So yeah doing some researching about stupid stuff I stumple across this Hermetism thing, which it's kinda explained in a boko called The Kybalion.
1. The Principle of Mentalism.

"THE ALL IS MIND; The Universe is Mental."

2. The Principle of Correspondence.

"As above, so below; as below, so above."

3. The Principle of Vibration.

"Nothing rests; everything moves; everything vibrates."

4. The Principle of Polarity.

"Everything is Dual; everything has poles; everything has its
pair of opposites; like and unlike are the same; opposites are
identical in nature, but different in degree; extremes meet;
all truths are but half-truths; all paradoxes may be
reconciled."

5. The Principle of Rhythm.

"Everything flows, out and in; everything has its tides;
all things rise and fall; the pendulum-swing manifests in
everything; the measure of the swing to the right is the
measure of the swing to the left; rhythm compensates."

6. The Principle of Cause and Effect.

"Every Cause has its Effect; every Effect has its Cause;
everything happens according to Law; Chance is but a name
for Law not recognized; there are many planes of causation,
but nothing escapes the Law."

7. The Principle of Gender.

"Gender is in everything; everything has its Masculine
and Feminine Principles; Gender manifests on all
planes."

What's really curious to me is that this book is from 1908, but this books only tries to explain the Hermetism teachings which dates over 8000 years ago.
And if you really try to understand what each principle says they seem pretty similar to many laws we know to date such from Newton (The principle of cause and effect), Heraclitus (Everything flows/moves) and many others.
How could someone from that time have this kind of knowledge? Could many people be inspired by these teachings? If so how come this is not being taught in some school/universities even if it's only one "subject" or a simple homework?
Welp this is it for my saturday night!

Truisms are considered such because they're vague enough to applicable in most any circumstance, particularly ones derived from observance of the natural world.

Why would people thounsads of years ago not be aware of the things around them more than people today? If anything it's exactly opposite because today we take most things for granted because it's handed to us on a platter without any real effort on our part, whereas our ancestors were actually invested in being aware of the world around them just to survive.
