As humans we are so easily trained. Well, may be we are not easily trained when it is against our natural propensity. We learn by watching, listening, and experiencing what others do before us. Most of our thoughts are taught by those sharing the same space during our rearing. If those we lived with have certain ways of viewing the world it usually influences our views.
What thoughts were you taught? Did they prove to be truth or fiction?
And you shall know the truth, and the truth shall make you free. John 8:32
