Any discussion into why “common sense isn’t that common,” requires understanding that different groups of people (personal, social, professional, etc.) make use of varied degrees of intelligence identifiable mainly to the group(s) in which they belong.  It isn’t that intelligence is “common” to everyone; instead it’s relative to a particular group sharing a certain skill set, set of beliefs, or experiences. One definition of common sense is “sound practical judgment derived from experience rather than study.” For that, I am definitely an advocate of common sense. I truly believe that there are many intelligent people in this world.  Maybe “relational” or “relate” should accompany the definition of common sense.  Take what we’ve learned and relate it to what needs to be done.  And with so many intelligent people in this world how do we level the varied degrees of intelligence? Through conversation.  As a witness to all that we share here through conversation, I express my gratitude and respect for any educator, formal or informal, whose education is gained from education and/or experience, who has shared selflessly to make all of us more intelligent.  There is so much we can learn from one another. Thank you for your support and continued success in all your endeavors.
