Quotes from Carl Sagan

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.

Geometry existed before the Creation. It is co-eternal with the mind of God Ãƒ¢Ã¢'¬Ã‚¦ Geometry provided God with a model for the Creation Ãƒ¢Ã¢'¬Ã‚¦ Geometry is God Himself." In

Condon, quick on his feet, replied that the accusation was untrue. He was not a revolutionary in physics. He raised his right hand: "I believe in Archimedes' Principle, formulated in the third century B.C. I believe in Kepler's laws of planetary motion, discovered in the seventeenth century. I believe in Newton's laws.…" And on he went, invoking the illustrious names of Bernoulli, Fourier, Ampère, Boltzmann, and Maxwell.

Huygens was, of course, a citizen of his time. Who of us is not? He claimed science as his religion and then argued that the planets must be inhabited because otherwise God had made worlds for nothing.

We might have thought that the horrors of World War II and the Holocaust were enough to innoculate us against the toxins there revealed and unleashed. But our resistance quickly fades. A new generation gladly abandons its critical and skeptical faculties.

Our passion for learning is our tool for survival.

Those who seek power at any price detect a societal weakness, a fear that they can ride into office. It could be ethnic differences, as it was then, perhaps different amounts of melanin in the skin; different philosophies or religions; or maybe it's drug use, violent crime, economic crisis, school prayer, or "desecrating" (literally, making unholy) the flag. Whatever the problem, the quick fix is to shave a little freedom off the Bill of Rights.

Those who make uncritical observations or fraudulent claims lead us into error and deflect us from the major human goal of understanding how the world works. It is for this reason that playing fast and loose with the truth is a very serious matter.

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.

Nietzsche mourns the loss of "man's belief in his dignity, his uniqueness, his irreplace-ability in the scheme of existence." For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
