"What I dream of is an art of balance, of purity and serenity devoid of troubling or depressing subject matter - a soothing, calming influence on the mind, rather like a good armchair which provides relaxation from physical fatigue."
"The intellectual roots of critical thinking are as ancient as its etymology, traceable, ultimately, to the teaching practice and vision of Socrates 2,500 years ago who discovered by a method of probing questioning that people could not rationally justify their confident claims to knowledge. Confused meanings, inadequate evidence, or self-contradictory beliefs often lurked beneath smooth but largely empty rhetoric. Socrates established the fact that one cannot depend upon those in "authority" to have sound knowledge and insight. He demonstrated that persons may have power and high position and yet be deeply confused and irrational. He established the importance of asking deep questions that probe profoundly into thinking before we accept ideas as worthy of belief." http://www.criticalthinking.org/pages/a-brief-history-of-the-idea-of-critical-thinking/408
