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.

Three key humanist virtues are courage, cognition, and caring - not dependence, ignorance, or insensitivity to the needs of others.

We need to be skeptical of utopianists who offer unreliable totalistic visions of other worlds and strive to take us there. We need some ideals, but we also need to protect ourselves from the miscalculations and misadventures of visionaries.

No one is infallible, and no one can claim a monopoly on truth or virtue. It would be contradictory for skepticism to seek to translate itself into a new faith.

I believe that a person should take an affirmative outlook. There are always problems in life, old and new, uncertainties, and unexpected contingencies. The optimal way to deal with this is not to give up in despair, but to move ahead using the best intelligence and resources that we have to overcome adversity.

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 theist can only find meaning by leaving this life for a transcendental world beyond the grave. The human world as he finds it is empty of 'ultimate purpose' and hence meaningless. Theism thus is an attempt to escape from the human condition; it is a pathetic deceit.
