Pero no sirve de nada tener esos derechos si no se usan: el derecho de libre expresión cuando nadie contradice al gobierno, la libertad de prensa cuando nadie está dispuesto a formular las preguntas importantes, el derecho de reunión cuando no hay protesta, el sufragio universal cuando vota menos de la mitad del electorado, la separación de la Iglesia y el Estado cuando no se repara regularmente el muro que los separa. Por falta de uso, pueden llegar a convertirse en poco más que objetos votivos, pura palabrería patriótica. Los derechos y las libertades o se usan o se pierden.
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.

A credulous mind … finds most delight in believing strange things, and the stranger they are the easier they pass with him; but never regards those that are plain and feasible, for every man can believe such.
Early in my studies, I was amazed and disappointed that such a view had ever been taken seriously, that for planets of other stars, absence of evidence had been considered evidence of absence.

Да поддържаш съзнанието си отворено, е добродетел, но — както веднъж каза космическият инженер Джеймс Оубърг — трябва да не е много отворено, за да не ти изпадне мозъкът.
