The roots of moral, ethical, and altruistic behavior are biological, not theological. Virtuous behavior has evolved as part of the evolutionary process which perpetuates the species. Humanism has come to mean emphasis on a secular, human-centered universe rather than a god-centered universe.
The responsibility for your life and the kind of world in which you live is yours and yours alone. You have the ability and responsibility to lead an ethical life of personal fulfillment that also aspires to the greater good of humanity. Visualize a world free from oppression and injustice, where all can realize their full human rights. Then, to the best of your ability, act to initiate a more just, less violent world. Encourage empirical truth, human understanding and cooperation, and conflict prevention. Confront unjust power structures, and challenge oppressive policies.
Virtue and humanism are the true drivers of peacebuilding and human development.
