The belief that one can immerse his mind (via eyes, ears, and so on) in any crap and not be affected is purely wishful thinking.
If people weren't affected by what they take into their minds via the senses, every dollar spent by the advertising industry would be wasted. There would be no advertising industry.
No one would be enlightened by reading inspirational literature or scripture, no one would become educated or wise by reading or hearing lectures or textbooks, etc.
It's merely common sense.
"It's merely common sense."
There sure is a lot of opposition to the idea.
