„If in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics...“

„What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe.“

— Stephen Hawking, A Brief History of Time
Context: Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? Ch. 12

„Liberty cannot be established without morality, nor morality without faith.“

— Alexis De Tocqueville, Democracy in America
Context: By the side of these religious men I discern others whose looks are turned to the earth more than to Heaven; they are the partisans of liberty, not only as the source of the noblest virtues, but more especially as the root of all solid advantages; and they sincerely desire to extend its sway, and to impart its blessings to mankind. It is natural that they should hasten to invoke the assistance of religion, for they must know that liberty cannot be established without morality, nor morality without faith; but they have seen religion in the ranks of their adversaries, and they inquire no further; some of them attack it openly, and the remainder are afraid to defend it. Original text: À côté de ces hommes religieux, j'en découvre d'autres dont les regards sont tournés vers la terre plutôt que vers le ciel ; partisans de la liberté, non seulement parce qu'ils voient en elle l'origine des plus nobles vertus, mais surtout parce qu'ils la considèrent comme la source des plus grands biens, ils désirent sincèrement assurer son empire et faire goûter aux hommes ses bienfaits : je comprends que ceux-là vont se hâter d'appeler la religion à leur aide, car ils doivent savoir qu'on ne peut établir le règne de la liberté sans celui des mœurs, ni fonder les mœurs sans les croyances ; mais ils ont aperçu la religion dans les rangs de leurs adversaires, c'en est assez pour eux : les uns l'attaquent, et les autres n'osent la défendre.
