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

I am in complete accordance with the authors claim about important truths being outrageous for the society which has accepted wisdom of the time. We as humans averse any new idea that tries to replace an existing pscyhology. New thinking or change is considered as a poetential threat or attack to the existing scenario and refuted by the society.

Cosider the era when desktop computers's arrived, these were made to simplify and make life more easier than it was before. Scientific calculations, Mathematics is a lot more simplier when we use these high tech machines. But, still some people do paper work for complex calculations, instead using the technology available.

In the era of galelio and copernicus, Europe was under the strong hold of the church. Things told by the church were taken as the final truth without even checking the correctness or truthfulness of the principle said. Church was under the impression that Earth is the supreme power and all other planets including Sun revolved aroung Earth. When Galelio presented his theory and said that sun is the centre of the solar system and every planet revolves aroung the system. Church din't wanted to change their belief's which were engraved in them during the course of time and considered galelio's theory as an attack on their belief's. But now we accepted the theory. Thus a theory once blasphemy now is a universal truth.

Also in the movie of rakesh roshan KOI MIL GAYA his contact discover of aliens was refused and un accepted by the scientist's. But later it was proved that actually the discovery was true.

To sum up i would say that new ideas and thinking initially is discarded, but later it is accepted as a universal truth.
