Skepticism is essential to the quest for knowledge, for it is in the seedbed of puzzlement that genuine inquiry takes root. Without skepticism, we may remain mired in unexamined belief systems that are accepted as sacrosanct yet have no factual basis in reality.

The skeptic has no illusions about life, nor a vain belief in the promise of immortality. Since this life here and now is all we can know, our most reasonable option is to live it fully.

The overriding need is "to develop a new Planetary Humanism" that will seek to preserve human rights and enhance human freedom and dignity and will emphasize our commitment "to humanity as a whole." The underlying ethical principle "is the need to respect the dignity and worth of all persons in the world community." Thinkers as diverse as Peter Singer and Hans Küng also emphasize the need for a new global ethic beyond nationalistic, racial, religious, and ethnic chauvinism.

Homo religiosus invents religious symbols, which he venerates and worships to save him from facing the finality of his death and dissolution. He devises paradise fictions to provide succor and support... In acts of supreme self-deception, at various times and in various places he has been willing to profess belief in the most incredible myths because of what they have promised him.

Many humanists have argued that happiness involves a combination of hedonism and creative moral development; that an exuberant life fuses excellence and enjoyment, meaning and enrichment, emotion and cognition.

We are not simply intellectual creatures. We wish to make love, to enjoy a gourmet dinner, to jog in the park, to cheer lustily at a ball game, to engage in spirited conversation with our friends, to play bridge or tennis, travel to exotic places, struggle with others to build a better world, and to enjoy the arts. The arts are so vital because they help to make life worth living. Music, poetry, literature, paintings, dance, and the theater are among our richest joys...The fine arts contribute immeasurably to the good life and that is why we cherish them.

It is not the courage to be that we must develop as much as the courage to become. We are responsible for our destiny. The meaning of life is not located in some hidden crevice in the womb of nature but is created by free persons, who are aware that they are responsible for their own futures and have the courage to take this project into their own hands.
