“Les questions s'enchaînent les unes aux autres, elles s'engendrent mutuellement. D'une part, les curiosités collectives se déplacent; d'autre part, la vérification/réfutation des hypothèses donne naissance à de nouvelles hypothèses, au sein de théories qui évoluent. L'enquête est donc indéfiniment relancée. Pas plus que la liste des faits, celle des questions ne saurait être close : il faudra toujours réécrire l'histoire.”
Douze leçons sur l'histoire, 1996, Chapitre 4 : Les questions de l'historien

If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are applied.

[In Pseudoscience] hypothesis are often framed precisely so that they are invulnerable to any experiment that offers a prospect of disproof, so even in principle they cannot be invalidated. Practitioners are defensive and wary. Skeptical scrutiny is opposed. When the pseudoscientific hypothesis fails to catch fire with scientists, conspiracies to suppress it are deduced.
