Good tests kill flawed theories; we remain alive to guess again.
Karl Popper
The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.
David Deutsch
(Coining the phrase ‘test of significance’): Critical tests of this kind may be called tests of significance, and when such tests are available we may discover whether a second sample is or is not significantly different from the first.
Ronald Fisher
'Without effort and change, human life cannot remain good. It is not a finished Utopia that we ought to desire, but a world where imagination and hope are alive and active
Bertrand Russell
[B]ut if there were machines bearing the image of our bodies, and capable of imitating our actions as far as it is morally possible, there would still remain two most certain tests whereby to know that they were not therefore really men.
Rene Descartes
Love is the foundation of all obedience. Without it, morality degenerates into mere casuistry. Love is the foundation of all knowledge. Without it religion degenerates into a chattering about Moses and doctrines and theories; a thing that will neither kill nor make alive, that never gave life to a single soul or blessing to a single heart, and never put strength into any hand in the conflict and strife of daily life.
