“The most original minds borrowed from one another.”

He looked on everything as imitation. The most original writers, he said, borrowed one from another. Boyardo has imitated Pulci, and Ariofio Boyardo. The instruction we find in books is like fire; we fetch it from our neighbour, kindle it as home, communicate it to others, and it becomes the property of all.
Historical and Critical Memoirs of the Life and Writings of M. de Voltaire (1786) by Louis Mayeul Chaudon, p. 348
What we find in books is like the fire in our hearths. We fetch it from our neighbors, we kindle it at home, we communicate it to others, and it becomes the property of all.
As translated in Geary's Guide to the World's Great Aphorists (2008), by James Geary, p. 373
Context: Thus, almost everything is imitation. The idea of The Persian Letters was taken from The Turkish Spy. Boiardo imitated Pulci, Ariosto imitated Boiardo. The most original minds borrowed from one another. Miguel de Cervantes makes his Don Quixote a fool; but pray is Orlando any other? It would puzzle one to decide whether knight errantry has been made more ridiculous by the grotesque painting of Cervantes, than by the luxuriant imagination of Ariosto. Metastasio has taken the greatest part of his operas from our French tragedies. Several English writers have copied us without saying one word of the matter. It is with books as with the fire in our hearths; we go to a neighbor to get the embers and light it when we return home, pass it on to others, and it belongs to everyone

“And so if any one would suppose that Æther (like our Air) may contain Particles which endeavour to recede from one another (for I do not know what this Æther is) and that its Particles are exceedingly smaller than those of Air, or even than those of Light: The exceeding smallness of its Particles may contribute to the greatness of the force by which those Particles may recede from one another, and thereby make that Medium exceedingly more rare and elastick than Air, and by consequence exceedingly less able to resist the motions of projectiles, and exceedingly more able to press upon gross Bodies, by endeavouring to expand it self.”

“[S]ince causes are four in number, to know them all is the business of the natural philosopher, who also referring to the cause why a thing is to all of them, viz. to matter, form, that which moves, and for the sake of which a thing subsists, physically assigns a reason. Frequently, however, three of these causes pass into one: for the cause why a thing is, and that for the sake of which it is, are one. But that which motion first originates, is in species the same with these… [T]here are three treatises; once concerning that which is immoveable; another concerning that which is moved, indeed, but is incorruptible; and a third concerning corruptible natures. So the cause of why a thing is, is assigned by him who refers to matter, to essence, and to the first mover… But there are two principles which are naturally motive; of which, one is not physical, because it does not contain in itself the principle of motion. And if there is any thing which moves without being moved, it is of this kind; as is that which is perfectly immoveable, that which is the first of all things, together with essence and form: for it is the end, and that for the sake of which a thing subsists. So that since nature is for the sake of something, it is also necessary to know this cause.”

“While the founding fathers agonized over the question 'particle' or 'wave', de Broglie in 1925 proposed the obvious answer 'particle' and 'wave'. Is it not clear from the smallness of the scintillation on the screen that we have to do with a particle? And is it not clear, from the diffraction and interference patterns, that the motion of the particle is directed by a wave? De Broglie showed in detail how the motion of a particle, passing through just one of two holes in screen, could be influenced by waves propagating through both holes. And so influenced that the particle does not go where the waves cancel out, but is attracted to where they cooperate. This idea seems to me so natural and simple, to resolve the wave-particle dilemma in such a clear and ordinary way, that it is a great mystery to me that it was so generally ignored.”
