"The heresy of one age becomes the orthodoxy of the next"

This quote by Helen Keller talks to the idea that what is thought about to be wrong or inappropriate in one era can end up being accepted and even commemorated in the next. This is frequently seen in the development of social standards, worths, and beliefs. For example, in the past, women were not allowed to vote, but today, women's suffrage is a widely accepted standard. Likewise, same-sex marriage was when considered to be a taboo, today it is widely accepted in lots of countries. This quote is a pointer that what is considered to be incorrect or inappropriate today might become accepted and even commemorated in the future. It is a pointer to be unbiased and to not be too fast to judge or condemn something that might be viewed as unconventional or controversial.
