“I have been aware from the outset (end of January 1959, the birthdate of the second paper in the citation) that the deep analysis of something which is now called Kalman filtering were of major importance. But even with this immodesty I did not quite anticipate all the reactions to this work. Up to now there have been some 1000 related publications, at least two Citation Classics, etc. There is something to be explained.
To look for an explanation, let me suggest a historical analogy, at the risk of further immodesty. I am thinking of Newton, and specifically his most spectacular achievement, the law of Gravitation. Newton received very ample "recognition" (as it is called today) for this work. it astounded - really floored - all his contemporaries. But I am quite sure, having studied the matter and having added something to it, that nobody then (1700) really understood what Newton's contribution was. Indeed, it seemed an absolute miracle to his contemporaries that someone, an Englishman, actually a human being, in some magic and un-understandable way, could harness mathematics, an impractical and eternal something, and so use mathematics as to discover with it something fundamental about the universe.”

The Principles of Success in Literature (1865)
Context: Men who are never flagrantly dishonest are at times unveracious in small matters, colouring or suppressing facts with a conscious purpose; and writers who never stole an idea nor pretended to honours for which they had not striven, may be found lapsing into small insincerities, speaking a language which is not theirs, uttering opinions which they expect to gain applause rather than the opinions really believed by them. But if few men are perfectly and persistently sincere, Sincerity is nevertheless the only enduring strength.
The principle is universal, stretching from the highest purposes of Literature down to its smallest details. It underlies the labour of the philosopher, the investigator, the moralist, the poet, the novelist, the critic, the historian, and the compiler. It is visible in the publication of opinions, in the structure of sentences, and in the fidelity of citations.

Context: She looked at me suddenly. “Johannes? What do you wish to be? What would you like to become?”
I did not know, and I told her so, but the question worried me. Should I know?  “There is time,” she said, “but the sooner you know, the sooner you can plan. To have a goal is the important thing, and to work toward it. Then, if you decide you wish to do something different, you will at least have been moving, you have been going somewhere, you will have been learning. "
