Knowledge is a dynamic ever-evolving process, not a static condition.
Any act of imparting insight is only a starting point for further inquiry.

The danger to knowledge is not TED talks, Internet Memes, and out-of-context quotes posted on Twitter.
The danger to knowledge is any attitude which stifles or discourages inquiry wherever inquiry happens to be inspired.
