If those committed to the quest fail they will be forgiven. When lost they will find another way. The moral imperative of humanism is the endeavor alone whether successful or not provided the effort is honorable and failure memorable.
I am free because I know that I alone am morally responsible for everything I do. I am free no matter what rules surround me. If I find them tolerable I tolerate them if I find them too obnoxious I break them. I am free because I know that I alone am morally responsible for everything I do.
The balance of private good and general welfare is at the bottom of civilized morals but the morals of the Heroic Age are founded on individuality and on nothing else.
Just as we reject racism sexism ageism and heterosexism we reject speciesism. The species of a sentient being is no more reason to deny the protection of this basic right than race sex age or sexual orientation is a reason to deny membership in the human moral community to other humans.
I would always encourage people of any age not to be so quick to follow other people's truths but to search and follow your own moral code and live by your own integrity and mostly just be brave.
Morality comes with the sad wisdom of age when the sense of curiosity has withered.
