"Important truths begin as outrageous, or at least uncomfortable..."

"Important truths begin as outrageous, or at least uncomfortable, attacks upon the accepted wisdom of the time."

The nature of human beings perception varries from person to person.Poeple tends to think ,accept it when they meet consenses of mind.Some accept or deny the facts proved .Somme may require more elloberate ways to proove and others may require a cleric approach for the same.

Clearly from the past ,numerous theories have been devoleped by famous scientist based on their experiment and observation ,they we subjected to even hostile measures when they approached ordinary folks.The poeple were never willing to accept some these inventions suddenly because they me feel its against their belief or customs .For ex a misconseption regarding the earth was prevailed in olden days. when poeple started to move towards the sea they felt that the beleif that earth is round may be proove wrong.They were obssesed with the fact that was thought in their mind and not willing to change the perception .But later poeple were forced to accept the truth ,earth was never a flat one .

As we can see the approach to truths becomes outrageous first as it is the nature of human beings to negate a truth.
