The aim is to love God because the pure heart loves loving God and because the true mind knows He deserves it. Unlike the accusations and beliefs of the critics and skeptics, it is neither an obligation of duty; nor a fear of damnation; nor a wish for power; nor a desire to appear more righteous than others; nor because God needs it; but because through all love, truth, reason, faith, honesty, and joy in and beyond oneself and the universe, He is worthy.

Tell a devout Christian that his wife is cheating on him, or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it. Tell him that the book he keeps by his bed was written by an invisible deity who will punish him with fire for eternity if he fails to accept its every incredible claim about the universe, and he seems to require no evidence what so ever.

Skepticism is thus a resting-place for human reason, where it can reflect upon its dogmatic wanderings and make survey of the region in which it finds itself, so that for the future it may be able to choose its path with more certainty. But it is no dwelling-place for permanent settlement. Such can be obtained only through perfect certainty in our knowledge, alike of the objects themselves and of the limits within which all our knowledge of objects is enclosed.

You're looking at me as though I'm weird. My God! Are you so out of touch with most of America, most of which believes in the Devil? I mean, Jesus Christ believed in the Devil! It's in the Gospels! You travel in circles that are so, so removed from mainstream America that you are appalled that anybody would believe in the Devil! Most of mankind has believed in the Devil, for all of history. Many more intelligent people than you or me have believed in the Devil.

Men became scientific because they expected Law in Nature, and they expected Law in Nature because they believed in a Legislator. In most modern scientists this belief has died: it will be interesting to see how long their confidence in uniformity survives it. Two significant developments have already appeared—the hypothesis of a lawless sub-nature, and the surrender of the claim that science is true. We may be living nearer than we suppose to the end of the Scientific Age.

There is a horrifying loneliness at work in this time. No, listen to me. We lived six and seven to a room in those days, when I was still among the living. The city streets were seas of humanity; and now in these high buildings dim-witted souls hover in luxurious privacy, gazing through the television window at a faraway world of kissing and touching. It is bound to produce some great fund of common knowledge, some new level of human awareness, a curious skepticism, to be so alone.

Creationists argue that natural selection is only a negative process, and therefore cannot create anything. Chopra argues that skepticism is only a negative process, and therefore does not lead to knowledge. Both are wrong for the same reasons. They ignore the generation of diversity and new ideas upon which natural selection and skepticism acts. Weeding out the unfit is critical to both – natural selection allows evolution to proceed, and skepticism allows science to advance.

The major religions on the Earth contradict each other left and right. You can't all be correct. And what if all of you are wrong? It's a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I'm not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they're called hypotheses, not inspiration and not revelation.

Every aspect of Nature reveals a deep mystery and touches our sense of wonder and awe. Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.

So my antagonist said, "Is it impossible that there are flying saucers? Can you prove that it's impossible?" "No", I said, "I can't prove it's impossible. It's just very unlikely". At that he said, "You are very unscientific. If you can't prove it impossible then how can you say that it's unlikely?" But that is the way that is scientific. It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

How have people come to be taken in by The Phenomenon of Man? We must not underestimate the size of the market for works of this kind [pseudoscience/'woo'], for philosophy-fiction. Just as compulsory primary education created a market catered for by cheap dailies and weeklies, so the spread of secondary and latterly tertiary education has created a large population of people, often with well-developed literary and scholarly tastes, who have been educated far beyond their capacity to undertake analytical thought.

Jesus' willingness to accommodate Thomas' unbelief is a reminder that God can handle our doubt. And that the rationalist doesn't need to see, touch, or run a lab test in order to believe in the resurrected Christ. Jesus told him, “You believe because you have seen me. Blessed are those who believe without seeing me” (Jn 20:29) This is not a plea to accept what goes against reason, but it is an invitation to discover a faith that goes beyond it. The example of Thomas is for the stubborn skeptic in us all.

If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power. But if the citizens are educated and form their own opinions, then those in power work for us. In every country, we should be teaching our children the scientific method and the reasons for a Bill of Rights. With it comes a certain decency, humility and community spirit. In the demon-haunted world that we inhabit by virtue of being human, this may be all that stands between us and the enveloping darkness.

I believe the experiences reported in this book are reproducible by anyone who wishes to try. I went to Africa. You can go to Africa. You may have trouble arranging the time or the money, but everybody has trouble arranging something. I believe you can travel anywhere if you want to badly enough.And I believe the same is true of inner travel. You don't have to take my word about chakras or healing energy or auras. You can find about them for yourself if you want to. Don't take my word for it. Be as skeptical as you like.Find out for yourself.

When anyone tells me that he saw a dead man restored to life, I immediately consider with myself whether it be more probable that this person should either deceive or be deceived or that the fact which he relates should really have happened. I weigh the one miracle against the other and according to the superiority which I discover, I pronounce my decision. Always I reject the greater miracle. If the falsehood of his testimony would be more miraculous than the event which he relates, then and not till then, can he pretend to command my belief or opinion.
