Reason requires an open mind. An open mind considers facts, even if these facts are contradictory to what one wants to believe due to bias, prejudice, preconceived notions, or mindset.
A closed mind clings to intolerance, suppressing proper reasoning power. A closed mind has established an unwise resolve and will not consider crucial facts when such information does not already align itself with the current mindset.
Where then, is the key that opens the closed mind?
Find that key and a lot of closed minds can be freed.
