French philosopher Michel Foucault thought that the role of intellectuals was
"to see and speak based on an intuitive reaction to what is intolerable."As far as I can tell this is the model that many contemporary thinkers and dissenters follow, pointing out all that is wrong, disturbing and immoral in the world and attempting, if they are strong minded, to offer solutions.
The intellectual conscience is however quite rare, most people suffering from 'eyes wide shut' syndrome and generally being content with thinking in cliché and common utterance. John Lennon thought that theirs was an easier life:
"Living is easy with eyes closed, misunderstanding all that you see."That being said many people are not genuinely capable of intellectual thought as levels of ability and desire in this area vary.
