Martin Luther King Jr.   “The Strength to Love” chapter one:  

Rarely do we find people who willingly engage in hard, solid thinking.  There is an almost universal quest for easy answers and half-baked solutions.  Nothing pains some people more than having to think.

…  Our minds are constantly beginning invaded by legions of half-truths, prejudices, propaganda, and false facts.   ….  Soft-mindedness often invades religion.  This is why religion sometimes rejected new truth with a dogmatic passion.  …. (For some church goers) reason is looked upon as the exercise of a corrupt faculty.  Soft-minded persons have revised the Beatitudes to read: “Blessed are the pure in ignorance: for they shall see God”.    …. The shape of the world today does not permit us the luxury of soft-mindedness.  A nation or civilization that continues to produce soft-minded people purchases its own spiritual death on an installment plan.  But we must not stop with the cultivation of a tough mind. The Gospel demands a tender heart.
