We cannot remain silent when someone of the Pope's stature and credibility confuses religious principles for science

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.

The meaning of life is not to be discovered only after death in some hidden, mysterious realm; on the contrary, it can be found by eating the succulent fruit of the Tree of Life and by living in the here and now as fully and creatively as we can.

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.

A skeptic is one who is willing to question any truth claim, asking for clarity in definition, consistency in logic, and adequacy of evidence.

The beginning of wisdom is the awareness that there is insufficient evidence that a god or gods have created us and the recognition that we are responsible in part for our own destiny. Human beings can achieve this good life, but it is by the cultivation of the virtues of intelligence and courage, not faith and obedience, that we will most likely be able to do so.

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.
