Engraved portrait of Carl Sagan, facing right

Avoidable human misery is more often caused not so much by stupidity as by ignorance, particularly our ignorance about ourselves. I worry that, especially as the Millennium edges nearer, pseudoscience and superstition will seem year by year more tempting, the siren song of unreason more sonorous and attractive. Where have we heard it before? Whenever our ethnic or national prejudices are aroused, in times of scarcity, during challenges to national self-esteem or nerve, when we agonize about our diminished cosmic place and purpose, or when fanaticism is bubbling up around us — then, habits of thought familiar from ages past reach for the controls. The candle flame gutters. Its little pool of light trembles. Darkness gathers. The demons begin to stir.

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.

Additional quotes by Carl Sagan

The technological perils that science serves up, its implicit challenge to received wisdom, and its perceived difficulty, are all reasons for some people to mistrust and avoid it.

And yet, the chief deficiency I see in the sceptical movement is in its polarization: Us v. Them - the sense that we have a monopoly on the truth; that those other people who believe in all these stupid doctrines are morons; that if you're sensible, you'll listen to us; an if not, you're beyond redemption. This is unconstructive. It does not get the message across. It condemns the sceptics to permanent minority status; whereas, a compassionate approach that from the beginning acknowledges the human roots of pseudoscience and superstition might be much more widely accepted.

Ако всеки човешки мозък имаше само един синапс, което би означавало монументална глупост, ние бихме били способни само на две мозъчни състояния. Ако имахме два синапса, тогава 2 на втора - 4 състояния; три синапса - 2 на трета = 8 състояния; или казано общо, при N синапса - 2 на N състояния. Но човешкият мозък се характеризира с около 10 на 13 синапса. Така броят на различните състояния на човешкия мозък е 2 на тази степен; т.е. умножено по себе си десет трилиона пъти. Това е невъобразимо число, много по-голямо например от общия брой на елементарните частици (електрони и протони) в цялата Вселена, което е много под 2 на степен 10 на 13. Поради този огромен брой на функционално различни конфигурации на човешкия мозък няма двама души, дори сред отгледаните заедно еднояйчни близнаци, между които да има особено силна мозъчна прилика. Тези огромни числа може би обясняват и непредсказуемостта на човешкото поведение и онези моменти, в които с постъпките си успяваме да изненадаме дори себе си. Действително, изправени пред тези числа, странното е, че в човешкото поведение изобщо има някакви закономрности. Отговорът може би е, че всички възможни мозъчни състояния далеч не са оползотворени и вероятно съществуват огромен брой умствени конфигурации, които никога не са осъществявани или дори загатвани за което и да било човешко същество в историята на човечеството. От такава перспектива всяко човешко създание е истинска рядкост и светостта на отделния човешки живот става напълно достоверно етично последствие.
