The thing about most of humans that most grates me is their inability to reason, the majority have been taught values and certain fundamental concepts from their youth that essentially seem immovable (even if the consept is blatantly wrong).
The abilty to reason both from your starting point and at the same time to be able to investigate your consept from a another point of view.
Is the difference between a mind that reasons, investigates and weighs up each concept before drawing a conclusion which is based on facts.
Questions stimulate thought; thought stimulates opportunities, possibilities, probabilities and answers.
All answers have value, not all answers have the same value, and value is determined by content, knowledge, logic and reason.
The battle for the mind of a person who refuses to use knowledge and reason is already lost before it has begun.
