Critical thinking

"WSJ writes:

Critical thinking means being able to evaluate evidence, to tell fact from opinion, to see holes in an argument, to tell whether cause and effect has been established and to spot illogic. "

Critical thinking is the exercise of the brain.
It is moving neurons and synapses.
The more you exercise your brain the more critical you become.
It is where progress and innovations come from.
It is elaborating other people's ideas, finding the good and the bad.
Discharging the bad and developing the good.
Without critical thinking, man would not have evolved.
Critical thinking is the meaning of our lives.

However, critical thinking would not exist without communication.
Ideas make new ideas and from new ideas, this world grows.

Critical thinking should be encouraged by every democratic and progressive society.
That is why "Today’s democracies" do not do it...
