This is the aspect of secular humanism that I relate to -- not sure I agree with the other stuff posted here.

From Portland Humanists:
"Humanists believe in a scientific, rather than a supernatural or divine, explanation for how we all (plants, animals, planets, stars, galaxies) got to where we are.
Humanists believe that people are capable of both good and evil all on their own, and we work hard for the good.
Humanists believe it is our purpose to become our very best selves, take care of each other, and to take good care of the planet where we live. We act this way not to earn some eternal reward, or to avoid some eternal punishment, but because it's ethical."
