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.

We have never denied that it is possible, indeed probable, that other forms of life, even intelligent life, exist in the universe. But this is different from the belief that we are now being visited by extraterrestrial beings in spacecraft, that they are abducting people, and the there is a vast government cover-up.

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.

In contemporary society secular humanism has been singled out by critics and proponents alike as a position sharply distinguishable from any religious formulation. Religious fundamentalists in the United States have waged a campaign against secular humanism, claiming that it is a rival "religion" and seeking to root it out from American public life. Secular humanism is avowedly non-religious. It is a eupraxsophy (good practical wisdom), which draws its basic principles and ethical values from science, ethics, and philosophy.

Human life has no meaning independent of itself. There is no cosmic force or deity to give it meaning or significance. There is no ultimate destiny for man. Such a belief is an illusion of humankind's infancy. The meaning of life is what we choose to give it. Meaning grows out of human purposes alone. Nature provides us with an infinite range of opportunities, but it is only our vision and our action that select and realize those that we desire.

As I see it, creative achievement is the very heart of the human enterprise... The destiny of man, of all men and of each man, is that he is condemned to invent what he will be - condemned if he is fearful but blessed if he welcomes the great adventure. We are responsible in the last analysis, not simply for what we are, but for what we will become; and that is a source of either high excitement or distress.
