A timeless Carl Sagan quote:
“We humans long to be connected with our origins so we create rituals. Science is another way to experience this longing. It also connects us with our origins, and it too has its rituals and its commandments. Its only sacred truth is that there are no sacred truths. All assumptions must be critically examined. Arguments from authority are worthless. Whatever is inconsistent with the facts — no matter how fond of it we are — must be discarded or revised. Science is not perfect. It is often misused. It is only a tool, but it is the best tool we have — self-correcting, ever changing, applicable to everything. With this tool we vanquish the impossible; with the methods of science we have begun to explore the cosmos. For the first time scientific discoveries are widely accessible. Our machines — the products of our science — are now beyond the orbit of Saturn. A preliminary spacecraft reconnaissance has been made of 20 new worlds. We have learned to value careful observation, to respect the facts even when they are disquieting, when they seem to contradict “conventional wisdom.” —Carl Sagan
