Si sentimos profundo respeto por otros seres humanos como iguales receptores de este preciso patrimonio de cinco mil millones de años de evolución, ¿por qué no ha de aplicarse tal identificación también a todos los demás organismos de la Tierra que son, asimismo, el producto del mismo número de años de evolución? Cuidamos de una pequeña fracción de organismos de la Tierra como, por ejemplo, perros, gatos y vacas -porque son útiles o porque nos halagan-. Pero las arañas, las salamandras, el salmón y el girasol son igualmente nuestros hermanos y hermanas.

About Carl Sagan

Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

But I could be wrong.

Much of the difficulty in attempting to restructure American and other societies arises form this resistance by groups with vested interests in the status quo. Significant change might require those who are now high in the hierarchy to move downward many steps. This seems to them undesirable and its resisted.

It is pointless to worry about the possible malevolent intentions of an advanced civilization with whom we might make contact. It is more likely that the mere fact they have survived so long means they have learned to live with themselves and others. Perhaps our fears about extraterrestrial contact are merely a projection of our own backwardness, an expression of our guilty conscience about our past history: the ravages that have been visited on civilizations only slightly more backward than we.
