It is said that in nature nothing is wasted, everything is transformed. The question is how the same elements are combined.
By repeating what is heard without questioning the veracity or validity of what is said, one is helping to perpetuate a belief that may be false or pernicious.
If you reject everything you hear on principle, simply by thinking you have your own opinion if you are against it, you think you are changing without realizing that it did not move an iota of the situation of power of the questioned phrase. Who runs the game is the one who forces the other to play the opposition indiscriminately.
If you recreate what you hear and pass it through the sieve of your own reasoning, by confronting that statement with data, with information from different sources, and building a creative statement that coherently organizes the observation of the facts with one’s own interpretation of them, new possibilities of action open.
