The thing Men are most scared of is the Unknown.

When a man can identify this "Unknown", he is immediatly more at ease. But, "not knowing" triggers his process of imagination. Then appears in us our inner demons, our "personnal worst".  And while we believe we are fighting the darkness, we are actually fighting the phantasmagorical monsters of our unconscious. Though, it is when the human meets  an new phenomenon which is unidentified  that his mind works at its best level. He is attentive. He is awaken.  The Unkonown excites and fascinates us at the same time. He fears it but hopes to know if his brain will be able to adapt itself to this change.

As long as something is not named, it has a power of challenge for the humanity.

 

That is why we believe in things.
