What is knowledge? Ask Plato.

   Neuroscience too.

   2500 years ago, Plato came up with this idea.

   2500 years later, neuroscience shows that the amygdala feeds our
   rational side. Those with broken amygdalas are forever in a
   process of weighing things out logically, taking months to make
   simple conclusions. Why? Because their belief-system; that extra
   emotional *push* by the Amygdala doesn't lock it into place,
   telling you, ''I KNOW THIS TO BE TRUE''.

   Are there objective truths? Heck if I know. It's your brain. Use
   it how you like. I just know we have beliefs. It all starts from
   there. What you do with those beliefs is up to you.
