Explicit vs Implicit Knowledge

[robvalue]

Ummmm. . . link the video?

Also. . . there's no explicit knowledge which isn't rooted in implicit "knowledge."  For example, I know that the things I touch and interact with are real, and this in a sense is an act of faith.

Sure, we make a fundamental assumption that what we think is real is actually real.

It's not strictly necessary to do so, though. It's "real" in as much as it is part of the reality we are experiencing. Whether that reality ultimately correlates to anything else or not is only of philosophical importance. From a pragmatic point of view, it makes no difference.
