where did you get that "knowledge" from?

Knowledge (perceivable) one got through all; understanding (suggested) one gets from one another. One cannot hold onto knowledge, since it moves, which is why others tempt one to understand aka hold onto each others verbal diarrhea.

it might all begin with gradually infiltrating

Nature implies an ongoing process; each temporary being within implies a solid (life) filtering a liquid (inception towards death). That's the foundation of infiltration.

Ignoring a moving process (perceivable inspiration) for holding onto a product (suggested information) permits few to set additional filters into many. That's the infiltration you talk about.

the process of teaching a person

Teaching one another isn't a process, but a product, hence buying (student) and selling (teacher). Person implies the ignored process aka per sonos (by sound).

to accept a set of beliefs

Aka ones consent (accept) to a suggestion by another (set), while holding onto it (believe)...holding onto a product contradicts being within a process.

once a "belief" begins

Aka at the moment one gives consent to a suggestion by another.

couldn't you just "bust", whatever other claim with real proof

Reality moves; fictitious claims (consent) and proofs (suggestion) tempt one to hold onto, while ignoring that reality moves.

scientific evidence

Science/scio - "to know" implies each ones perception within all perceivable..suggested scientism tempts one to ignore that.

Evidence implies as perceived by one...not as suggested by another. One cannot share evidence without tempting others to contradict what's evident to each of them.

how about film clips I saw

Aka moving pictures (film) shaped by captured moments (photo)...distracting one from being (life) within momentum (inception towards death) of motion.

Momentum cannot be captured by those within, neither does moving (film) captured moments (photo) represent reality...only fictitious mimicry.

if I'd look around...

...then I'd confine myself to circular logic, while ignoring that all perceivable directs through each ones perception.

Perception isn't circular...suggestion is...if one consents to hold onto it.

Here's the sleight of hand... https://www.youtube.com/watch?v=ruKCw797JM4

• I'm gettin' bugged driving up and down (life) the same old strip (inception towards death)
• I gotta find a new place (suggestion) where the kids are hip (joined by consent)
• My buddies and me (consenting many) are getting real well known (by suggesting few)
• Yeah, the bad guys know us (from outside) and they leave us alone (fighting inside)
• I get around (Get around, 'round, 'round, I get around)...aka circular logic within self and conflicts of reason against others.

hang on

Hanging onto suggested while being (perception) within a process (perceivable) implies ignorance.
