It serves the purpose of not serving a purpose, surely quite a valid one.
Peter Greenaway
To say that prediction is the purpose of a scientific theory is to confuse means with ends. It is like saying that the purpose of a spaceship is to burn fuel. ... Passing experimental tests is only one of many things a theory has to do to achieve the real purpose of science, which is to explain the world. (Ch. 1)
David Deutsch
Prediction can never be absolutely valid and therefore science can never prove some generalization or even test a single descriptive statement and in that way arrive at final truth.
Gregory Bateson
The most important form of incremental change is the decision by the individual to become vegan. Veganism, or the eschewing of all animal products, is more than a matter of diet or lifestyle; it is a political and moral statement in which the individual accepts the principle of abolition in her own life. Veganism is the one truly abolitionist goal that we can all achieve—and we can achieve it immediately, starting with our next meal.
Gary L. Francione
There is only one valid definition of a business purpose: to create a customer.
