Feynman on knowing the name of something

[UnbornTao]

What if we apply this principle to everything that is conceived and perceived? 

[Joseph Maynor]

This is a good insight but most people think knowing the name or class of something is knowing what it is in essence.  Even physicists like Feynman.

Is it possible that all of us do the same when it comes to perceiving any given object?

In other words, do we assume our perception is reality or the same as what exists? (Not as a philosophy but as a factual happening?)

How can we even recognize this as such, if it is true?

Based on this assumption, it's virtually impossible to see a contrast for us to estimate what reality is other than our perception of it - except as an intellectual possibility that doesn't touch or alter what's experienced, or assumed.
