Quotes about Carl sagan

The beauty of a living thing is not the atoms that go into it but the way the atoms are put together.  The cosmos is also within us.  We're made of star stuff, we are a way for the cosmos to know itself.

Science is not only compatible with spirituality; it is a profound source of spirituality. When we recognize our place in an immensity of light-years and in the passage of ages, when we grasp the intricacy, beauty, and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual. So are our emotions in the the presence of great art or music or literature, or of acts of exemplary selfless courage such as those of Mohandas Gandhi or Martin Luther King, Jr.

The notion that science and spirituality are mutually exclusive does a disservice to both.

We are a way for the cosmos to know itself.

There are many hypotheses in science which are wrong. That's perfectly all right; they're the aperture to finding out what's right. Science is a self-correcting process. To be accepted, new ideas must survive the most rigorous standards of evidence and scrutiny.

We are like butterflies who flutter for a day and think its forever.

The use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.

We are star-stuff.

You have to know the past to understand the present.

Absence of evidence is not evidence of absence.
