We should learn humility, especially in applying our moral codes. Here is a quote from Alfred North Whitehead which applies quite well to the recent legal struggles for full equality:

"Moral codes have suffered from the exaggerated claims made for them. The dogmatic fallacy has here done its worst. Each such code has been put out by a God on a mountain top, or by a Saint in a cave, or by a divine Despot on a throne, or, at the lowest, by ancestors with a wisdom beyond later question. In any case, each code is incapable of improvement; and unfortunately in details they fail to agree either with each other or with our existing moral intuitions. The result is that the world is shocked, or amused, by the sight of saintly old people hindering in the name of morality the removal of obvious brutalities from a legal system."
