Sometimes the search for truth is discomforting. In fact, I would go so far as to claim that if no one ever complained about being offended or feeling intimidated by the learning environment we are probably not doing our jobs as teachers and learners. We must distinguish between legitimate and illegitimate offense. Like preaching, teaching and learning are not meant to be feel-good therapy. Another substitute for truth that may tempt us is practicality.
Truth is an end in itself.
Whether knowing it yields pragmatic results such as helping find a job, living a more successful life in society, or feeling good about oneself is secondary and should never become the primary concern in evaluating curricula and instruction. There are two more destructive alternatives to truth that are rampant in our modern-becoming postmodern culture that may attract us and intrude upon us from time to time. They are a bit more subtle and academic and therefore difficult to explain or grasp. But for that very reason we need to learn about them and be on our guard if and when they tempt us. They are the deconstructionist and ideological quicksands that suck objective truth down into oblivion.
