A perception is a set of assumptions about a certain idea, event, phenomenon , person or group. It depends upon the Intelligence level of the perceiver and the circumstances in which the idea, event, phenomenon, person or group is being perceived. There can be more than one perception of the same event, phenomenon, action, idea, person or group or let us call it reality in short. If there are two observors perceiving the same reality they would arrive at different conclusions. The same is true about more than two observers.
Reality is relative and it is perceived subjectively as a product of one’s intelligence level and external conditions. To a person who knows about the biology of a man, the actions of a person mean something else while for another person who is a student of literature the same actions has different meaning. A person living with a fatal disease has different priority in life than a person who enjoys good health. A person who is struggling for economic survival due to his poverty might not indulge in highly aesthetic activities and would consider them as secondary while another person who considers self realisation and spiritual achievement as his summum bonum might prefer death over a life which just aims at achieving sensual and instinctual pleasures.
A society does not necessarily need to have the same perception of reality to live together in a collective form of existence. This also implies that diversity is the natural form of social existence and should be encouraged in order for the society to follow its natural route of evolution.
Variety in perception of reality leads to pluralistic and democratic culture in a society. It is the basis of freedom. Freedom gives birth to creativity and innovation. Progress emanates from the culture which reinforces creativity. Progress transforms old structures of the society into new one and gives birth to a culture which has the ability to support the innovations.
All the exploiter classes in the society like bureaucracy, military, clergy and landlords are aginst freedom of expressions and difference of opinion as their monoploy is challenged by the variety of opinions and perceptions in a society. The pillars of the ruling elite always support status quo and socio-political stagnation to expand and strengthen their network of exploitation. Blind following instead of research in religious inquiry, dictatorship instead of democracy in political realm, brahmanism instead of social equality in social affairs and capitalism instead of social justice in economic matters have been the basic postulates of life-philosophy propagated by these enemies of humanity througout human history.
