People, the narrative goes, are not to be trusted. People are bad. People are evil. People are axe murderers and monsters and worse. I don't buy it. Evil is a make-believe concept we've invented to deal with the complexities of fellow humans holding values and beliefs and perspectives different than our own—it's easier to dismiss an opinion as abhorrent than strive to understand it. Badness exists, sure, but even that's quite rare. By and large, humans are kind. Self-interested sometimes, myopic sometimes, but kind. Generous and wonderful and kind. No greater revelation has come from our journey than this.
All men are therefore of identical origin. Absolute uniformity prevails among the children of men, so far as their origin is concerned.
Consequently, all who are or have been, or will be assembled on earth, have a common purpose. Absolute uniformity prevails among men so far as their fundamental purpose is concerned.
Likewise, the destiny of all the spirits sent to earth, is the same.
Then, all will seem as if precisely alike. Whether or not we reach a given point at the same time, or all men have a common destiny. As far as the destiny of man is concerned, all are alike.
Man affect each other, every man is, in a measure, his brother's keeper.
