Letter to Saint-Venant (1845) as quoted by Michael J. Crowe, A History of Vector Analysis: The Evolution of the Idea of a Vectorial System (1967)

Attributed to Nietzsche on quotes sites and on social media, the original quotation is from An Introduction to the History of Psychology by B. R. Hergenhahn (2008, page 226) and is the author's summary of Nietzsche's ideas: "The meaning and morality of one's life come from within oneself. Healthy, strong individuals seek self-expansion by experimenting, by living dangerously. Life consists of an almost infinite number of possibilities, and the healthy person (the superman) explores as many of them as possible. Religions or philosophies that teach pity, humility, submissiveness, self-contempt, self-restraint, guilt, or a sense of community are simply incorrect. [...] For Nietzsche, the good life is ever-changing, challenging, devoid of regret, intense, creative, and risky."

Original: Se eu tivesse escrito o Rei Lear, levaria com remorsos toda a minha vida de depois. Porque essa obra é tão grande, que enormes avultam os seus defeitos, os seus monstruosos defeitos, as coisas até mínimas que estão entre certas cenas e a perfeição possível delas. Não é o sol com manchas; é uma estátua grega partida.

A note on this statement is included by Stillman Drake in his Galileo at Work, His Scientific Biography (1981): Galileo adhered to this position in his Dialogue at least as to the "integral bodies of the universe." by which he meant stars and planets, here called "parts of the universe." But he did not attempt to explain the planetary motions on any mechanical basis, nor does this argument from "best arrangement" have any bearing on inertial motion, which to Galileo was indifference to motion and rest and not a tendency to move, either circularly or straight.
