You don’t need metaphysical motives to do good to others. The first part is making sure that, as a collective, we do not continue to promote selfishness. Humans are social creatures. We did not survive and continue to thrive in nature because of our physical abilities, we thrived because of our ability to work together and adapt to our environment with human ingenuity and reason. Thumbs are helpful too. Jokes aside, the same concept relates to human nature, for all our faults there still lies within us all the ability to work together for the good of the tribe, family, country, and hopefully someday we will all see eachother as one family, or as you put it, one soul. ☮️
