That knowledge is power is a well known truth. But truth also has two sides. And so, the power of knowledge can have undesirable traits piling up, too. When knowledge is combined with power of the wrong kind, it can cause endless agony and destruction.
As Lord Acton said, "Power corrupts and absolute power corrupts absolutely". I know it is ironic and a paradox that both words can be incompatible. But the beauty of humans is that their minds find it easier to get twisted in the negative direction rather than towards straight thinking, simple thinking and positive thinking.
You can be in any profession, have any vocation but there is always a danger of developing arrogance, an illusion of superiority and ego on the path of knowledge, evidently in comparison with the less knowledgeable. There are two ways of handling knowledge. One, by wanting a monopoly over it and two, by spreading it. The tendency for a monopoly goes hand in hand with controlling the environment and its people whereas spreading knowledge opens the heart and enables a person to become like a tree which grows tall and gives shade unconditionally.
