A Quote by Carl Sagan

Science is a way of thinking much more than it is a body of knowledge. Its goal is to find out how the world works, to seek what regularities there may be, to penetrate to the connections of things-from subatomic particles, which may be the constituents of all matter, to living organisms, the human social community, and thence to the cosmos as a whole.
Science isn't just about solving this or that puzzle. It's about understanding how the world works: the whole world from the vastness of the cosmos to the particularity of an individual human life. It's worth thinking about how all the different ways we have to talk about the world manage to fit together.
Science is a way of thinking much more than it is a body of knowledge.
The width of a line may present the idea of infinity. An epigram may contain a world. In the same way, a small picture format may be much more living, much more leavening, stirring, awakening, than square yards of wall space.
Every subatomic interaction consists of the annihilation of the original particles and the creation of new subatomic particles. The subatomic world is a continual dance of creation and annihilation, of mass changing into energy and energy changing into mass. Transient forms sparkle in and out of existence, creating a never-ending, forever newly created reality.
A sound American is simply one who has put out of his mind all doubts and questionings, and who accepts instantly, and as incontrovertible gospel, the whole body of official doctrine of his day, whatever it may be and no matter how often it may change. The instant he challenges it, no matter how timorously and academically, he ceases by that much to be a loyal and creditable citizen of the republic.
Now the smallest Particles of Matter may cohere by the strongest Attractions, and compose bigger Particles of weaker Virture.... There are therefore Agents in Nature able to make the Particles of Bodies stick together by very strong Attraction. And it is the Business of experimental Philosophy to find them out.
The value of the Old Testament may be dependant on what seems its imperfection. It may repel one use in order that we may be forced to use it in another way-to find the Word in it...to re-live, while we read, the whole Jewish experience of God's gradual and graded self-revelation, to feel the very contentions between the Word and the human material through which it works.
One of the greatest dangers to peace lies in the economic pressure to which people find themselves subjected. One of the most practical things to be done in the world is to seek arrangements under which such pressure may be removed, so that opportunity may be renewed and hope may be revived.
Growing up human is uniquely a matter of social relations rather than biology. What we learn from connections within the family takes the place of instincts that program the behavior of animals; which raises the question, how good are these connections?
If you have come to these pages for laughter, may you find it. If you are here to be offended, may your ire rise and your blood boil. If you seek an adventure, may this song sing you away to blissful escape. If you need to test or confirm your beliefs, may you reach comfortable conclusions. All books reveal perfection, by what they are or what they are not. May you find that which you seek, in these pages or outside them. May you find perfection, and know it by name.
Each individual is a cosmos of organs, each organ is a cosmos of cells, each cell is a cosmos of infinitely small ones; and in this complex world, the well-being of the whole depends entirely on the sum of well-being enjoyed by each of the least microscopic particles of organized matter. A whole revolution is thus produced in the philosophy of life.
Science affects all our ways of thinking about the world: both the physical world, which, if I may make so bold, is easy to understand because it is regular and follows simple laws, and also the social world, which is more baffling and less predictable.
How can we find spiritual meaning in a scientific worldview? Spirituality is a way of being in the world, a sense of one’s place in the cosmos, a relationship to that which extends beyond oneself. . . . Does scientific explanation of the world diminish its spiritual beauty? I think not. Science and spirituality are complementary, not conflicting; additive, not detractive. Anything that generates a sense of awe may be a source of spirituality. Science does this in spades. (158-159)
Sciences usually advances by a succession of small steps, through a fog in which even the most keen-sighted explorer can seldom see more than a few paces ahead. Occasionally the fog lifts, an eminence is gained, and a wider stretch of territory can be surveyed-sometimes with startling results. A whole science may then seem to undergo a kaleidoscopic rearrangement, fragments of knowledge sometimes being found to fit together in a hitherto unsuspected manner. Sometimes the shock of readjustment may spread to other sciences; sometimes it may divert the whole current of human thought.
Subatomic particles do not just sit around being subatomic particles. They are beehives of activity.
The whole point of science is that most of it is uncertain. That's why science is exciting--because we don't know. Science is all about things we don't understand. The public, of course, imagines science is just a set of facts. But it's not. Science is a process of exploring, which is always partial. We explore, and we find out things that we understand. We find out things we thought we understood were wrong. That's how it makes progress.
