Models
From charlesreid1
Chapter 6 of my Ph.D. dissertation was titled "Data Collaboration Method for Validation", and the chapter began with these two quotes:
Essentially, all models are wrong, but some are useful.- George Box
The falseness of a judgement is for us not necessarily an objection to a judgement.- Friedrich Nietzsche, from Beyond Good and Evil
Via Gutenberg.org translation, "The falseness of an opinion is not for us any objection to it: it is here, perhaps, that our new language sounds most strangely." Gutenberg.org link
