"Controversial proposals, once accepted, soon become hallowed"

This quote by Dean Acheson suggests that once a controversial proposal is accepted, it quickly becomes accepted as the norm. This could be translated as a caution versus the dangers of accepting radical ideas too quickly, as they might become established in society and challenging to change. It might likewise be seen as a pointer that change is possible, and that even the most questionable proposals can end up being accepted if provided adequate time. This quote might be viewed as a call to action, encouraging individuals to be open up to originalities and to think about the potential benefits of change. Eventually, it suggests that even the most radical proposals can become accepted if offered the chance.
