Invention is not the product of logical thought, even though the final product is tied to a logical structure.
Through all the years of experimenting and research, I never once made a discovery. I start where the last man left off. All my work was deductive, and the results I achieved were those of invention pure and simple.
We enjoy great Advantages from the Inventions of others, we should be glad of an Opportunity to serve others by any Invention of ours, and this we should do freely and generously.
Though human ingenuity may make various inventions which, by the help of various machines answering the same end, it will never devise any inventions more beautiful, nor more simple, nor more to the purpose than Nature does; because in her inventions nothing is wanting, and nothing is superfluous.[Ancorachè lo ingiegnio vmano faccia iuētioni varie, rispōdedo co uari strumēti a u medesimo fine, mai esso troverà inuentione più bella, nè più facile, nè più brieue della natura, perchè nelle sue invenzioni nullo manca e nullo è superfluo.]
The Book of the science of Mechanics must precede the Book of useful inventions.[Il libro della scietia della machine va inazi al libro de giovameti.]
