Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.
Carl SaganWe on Earth have just awakened to the great oceans of space and time from which we have emerged.
Carl SaganOne of the saddest lessons of history is this: If weโve been bamboozled long enough, we tend to reject any evidence of the bamboozle. Weโre no longer interested in finding out the truth. The bamboozle has captured us. Itโs simply too painful to acknowledge, even to ourselves, that weโve been taken. Once you give a charlatan power over you, you almost never get it back.
Carl SaganIt's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology.
