Isaac Asimov Quotes

“Many years later he looked through one of my books and said, "How did you learn all this, Isaac?""From you, Pappa", I said."From me? I don't know any of this"."You didn't have to, Pappa", I said. "You valued learning and you taught me to value it. Once I learned to value it, the rest came without trouble."- Isaac Asimov (Isaak Yudovich Ozimov). It's been a good life.”

“Some readers may realize that this story, first published in 1956, has been overtaken by events. In 1965, astronomers discovered that Mercury does not keep one side always to the Sun, but has a period of rotation of about fifty-four days, so that all parts of it are exposed to the sunlight at one time or another.Well, what can I do except say that I wish astronomers would get things right to begin with?And I certainly refuse to change the story to suit their whims.”

“And so from then onwards, Daniel understood that the point of this grueling sundial project was not merely to plot the curve but to understand why each curve was shaped as it was. To put it another way, Isaac wanted to be able to walk up to a blank wall on a cloudy day, stab a gnomom into it, and draw all of the curves simply by knowing where shadow would pass. This was the same thing as knowing where the sun would be in the sky and that was the same as knowing where the Earth was in its circuit around the sun, and in its daily rotation. Though as months went on, Daniel understood that Isaac wanted to be able to do the same thing even if the blank wall happened to be situated on, say, the moon that Christiaan Huygens had lately discovered revolving around Saturn. Exactly how this might be accomplished was a question with ramifications that extended into such fields as would Isaac, and Daniel for that matter, be thrown out of Trinity College? Were the Earth and all the works of man nearing the end of a long, relentless decay that had begun with the expulsion from Eden, and that would very soon culminate in the apocalypse? Or might things actually be getting better, with the promise of continuing to do so? Did people have souls? Did they have free will?”

“For five years Isaac had been working eighteen hours a day.”

“I just wish moments weren’t so fleeting!' Isaac called to the man on the roof, 'They pass so quickly!' 'Fleeting?!' responded the tilling man, 'Moments? They pass quickly?! . . . Why, once a man is finished growing, he still has twenty years of youth. After that, he has twenty years of middle age. Then, unless misfortune strikes, nature gives him twenty thoughtful years of old age. Why do you call that quickly?' And with that, the tilling man wiped his sweaty brow and continued tilling; and the dejected Isaac continued wandering. 'Stupid fool!' Isaac muttered quietly to himself as soon as he was far enough away not to be heard.”

“Well, sir to say that when the impossible has been eliminated, whatever remains, however improbable, is the truth, is to make the assumption, usually justified, that everything that is to be considered has indeed been considered. Let us suppose we have considered ten factors. Nine are clearly impossible. Is the tenth, however improbable, therefore true? What if there were an eleventh factor, and a twelfth, & a thirteenth...”

“Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won't come in.”

“If I have seen further it is by standing on the shoulders of Giants.”

“Should one of them after having caught the greatness of Abraham's deed, but also the appallingness of it, venture out on the road, I would saddle my horse and ride along with him. At every stop before we came to the mountain in Moriah I would explain to him that he could still turn back, could rue the misunderstanding that he was called to be tried in a conflict of this nature, could confess that he lacked the courage, so that if God wanted Isaac God must take him himself.”

“Isaac basically knew just one thing for sure: Many are born, few flourish, all die. If you didn’t die as a sacrifice for God today, you would die of an incomprehensible plague tomorrow, or of undeserved starvation the day after, or of good old-fashioned senseless human slaughter before the next harvest. Life was short in those days and people were grateful for whatever they could get. They didn’t expect wireless video game consoles, fast German cars, dental insurance, anti-depressants, and a pension.”
