Beware of False Knowledge

To know yet to think that one does not know is best;
Not to know yet to think that one knows
will lead to difficulty.
- Lao Tzu

The greatest obstacle to discovery is not ignorance -
it is the illusion of knowledge.
- Daniel J. Boorstin

Beware of false knowledge;
it is more dangerous than ignorance.
- George Bernard Shaw

We want the facts to fit the preconceptions.
When they don't, it is easier to ignore the facts
than to change the preconceptions.
- Jessamyn West

Truth is not defined by
how many people believe something.
Ask. Question. Think.
Decide - for yourself.
- Jonathan Lockwood Huie

When you have a very strong FEELING that something is true, often it isn't.
WANTING something to be true doesn't make it true.
Likewise, being AFRAID that something is true doesn't make it true either.
