ولكنه عاد يتذكر أن الاستذكار للامتحان النهائي كان له تأثير معوق عليه بحيث إنه يجد أن "التفكير في أي معضلة علمية شيء كريه لمدة عام كامل، ... وإنه ليكاد يكون من المعجزات أن الطرق الحديثة للتعليم لم تخنق الفضول المقدس للمعرفة والبحث، لأن ذلك النبت الصغير الرقيق يحتاج أكثر ما يحتاج، إضافة إلى التشجيع المبدئي، إلى الحرية، فبدونها سوف يُدمر. ... وإني أؤمن بأن بوسع المرء أن يقضي على نهم حيوان مفترس في صحة جيدة إن هو أجبره بالسياط على أن يأكل بصورة مستمرة سواء كان جائعًا أم لا
Carl SaganEn lugar de juzgar a la gente por sus méritos y defectos individuales, nos concentramos en un par de detalles de información sobre ellos y a continuación los colocamos en una serie de casillas previamente establecidas.
Con eso nos ahorramos el esfuerzo de pensar, al precio en muchos casos de cometer una profunda injusticia.
More recently, books, especially paperbacks, have been printed in massive and inexpensive editions. For the price of a modest meal you can ponder the decline and fall of the Roman Empire, the origin of species, the interpretation of dreams, the nature of things. Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.

Think of the rivers of blood, spilled by all those generals and emperors, so that in glory and triumph, they could become the momentary masters, of a fraction of a dot...our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe - are challenged by that point of pale light.
Carl SaganConsider again that pale blue dot...imagine that you take a good long look at it, imagine that you are starring at it for any length of time, and then try to convinve yourself that God created the whole Universe for one of the ten million or so species of life, that inhabit that speck of dust
-Now take it one step further, imagine that it everything was created for a single shade of that species, or gender, or ethnic or religious subdivision. If this does not strike you as unlikely, pick another dot. Imagine it to be inhabited by another form of life. Tehy too cherish the notion of a god who has created everything for their benefit...how seriously do you take their claim?
Humans may crave absolute certainty; they may aspire to it; they may pretend, as partisans of certain religions do, to have attained it. But the history of science — by far the most successful claim to knowledge accessible to humans — teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us.

The laws of nature cannot be randomly reshuffled at the cusps [of an oscillating universe]. If the universe has already gone through many oscillations, many possible laws of gravity would have been so weak that, for any given initial expansion, the universe would not have held together. Once the universe stumbles upon such a gravitational law, it flies apart and has no further opportunity to experience another oscillation and another cusp and another set of laws of nature. Thus we can deduce from the fact that the universe exists either a finite age, or a severe restriction on the kinds of laws of nature permitted in each oscillation. If the laws of physics are not randomly reshuffled at the cusps, there must be a regularity, a set of rules, that determines which laws are permissible and which are not. Such a set of rules would comprise a new physics standing over the existing physics. Our language is impoverished; there seems to be no suitable name for such a new physics. Both 'paraphysics' and 'metaphysics' have been preempted by other rather different and, quite possibly, wholly irrelevant activities. Perhaps 'transphysics' would do.

The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground.

Once we lose our fear of being tiny, we find ourselves on the threshold of a vast and awesome Universe which dwarfs -- in time, in space, and in potential -- the tidy anthropocentric proscenium of our ancestors.
