These days, there seems to be nowhere left to explore. Victims of their very success, the explorers now, pretty much, stay home. Maybe it's a little early- maybe the time is not quite yet- but those other worlds, promising untold opportunities, beckon. Just now, there a great many mattters that are pressing in on us that compete for the money it takes to send people to other worlds. Should we solve those problems first, or are they a reason for going? Our planet and our solar system are surrounded by a New World ocean: the depths of space. It is no more impassable than the last.

Our God Is Alive and Well. Sorry About Yours.

El escepticismo tiene por función ser peligroso. Es un desafío a las instituciones establecidas. Si enseñamos a todo el mundo, incluyendo por ejemplo a los estudiantes de educación secundaria, unos hábitos de pensamiento escéptico, probablemente no limitarán su escepticismo a los ovnis, los anuncios de aspirinas y los profetas canalizados de 35.000 años. Quizá empezarán a hacer preguntas importantes sobre las instituciones económicas, sociales, políticas o religiosas. Quizá desafiarán las opiniones de los que están en el poder. ¿Dónde estaremos entonces?
Carl SaganScience is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.

In college, in the early 1950s, I began to learn a little about how science works, the secrets of its great success, how rigorous the standards of evidence must be if we are really to know something is true, how many false starts and dead ends have plagued human thinking, how our biases can colour our interpretation of evidence, and how often belief systems widely held and supported by the political, religious and academic hierarchies turn out to be not just slightly in error, but grotesquely wrong.

The others would then fall silent and she would continue about doped gallium arsenide detectors, or the ethanol content of the galactic cloud W-3. The quantity of 200-proof alcohol in this single interstellar cloud was more than enough to maintain the present population of the Earth, if every adult were a dedicated alcoholic, for the age of the solar system. The tamada had appreciated the remark.

Dreams are associated with a state called REM sleep, the abbreviation standing for rapid eye movement. The REM state is strongly correlated with sexual arousal. Experiments have been performed in which sleeping subjects are awakened whenever REM state emerges, while members of a control group are awakened just as often each night but not when they're dreaming. After some days, the control group is a little groggy, but the experimental group - the ones who are prevented from dreaming - is hallucinating in daytime. It's not that a few people with a particular abnormality can be made to hallucinate in this way; anyone is capable of hallucinations.

The Yale anthropologist Weston La Barre goes far as to argue that `a surprisingly good case could be made that much of culture is hallucination` and that `the whole intent and function of ritual appears to be... a group wish to hallucinate reality`.

There is child abuse, and there are such things as repressed memories. But there are also such things as false memories and confabulations, and they are not rare at all. Misrememberings are the rule, not the exception. They occur all the time. They occur even in cases where the subject is absolutely confident - even when the memory is a seemingly unforgettable flashbulb, one of those metaphorical mental photographs.
