The Difference Between Believing and Knowing

From Logic

"I don't believe, I know!"
- Carl Jung, when asked about his belief in 'god'

Believe

 1 a : to have a firm religious faith b : to accept as true
2 : to have a firm conviction
3 : to hold an opinion

Know

 1 a : to perceive directly : have direct cognition of 
b: to have understanding of
c: to recognize the nature of : DISCERN
(1) : to recognize as being the same as something previously known
(2) to be acquainted or familiar with
(3) : to have experience of
2 a : to be aware of the truth or factuality
b : to have a practical understanding

Believing is holding an opinion. Knowing is to have direct experience, to understand, and to have a practical understanding of some concept.

To further delineate the two different terms, it is important to realize that while one can "make- believe", one cannot "make-know".

Main Entry: [1]make-be┬Ělieve

pretending to believe

One can pretend to believe, because in order to believe, one does not need factual knowledge. You just make it up.

Of course, I suppose it is true that you can "pretend know" - but we usually call this lying.

When one maintains in an argument: "I don't believe, I know", without actually possessing direct cognition of, or evidence for, their proposition, they are in fact using a persuasive defintion (i.e. one that is misleading, which we otherwise refer to as lying. (Literally, pretending to know)
