“One strength of the communist system of the East is that it has some of the character of a religion and inspires the emotions of a religion. Unless the concept of peace based on law gathers behind it the force and zeal of a religion, it can hardly hope to succeed.”

The Artful Universe (1995)
Context: If a 'religion' is defined to be a system of ideas that contains unprovable statements, then Gödel taught us that mathematics is not only a religion, it is the only religion that can prove itself to be one.<!-- Ch. 5, p. 211

"The California Question" (10 June 1850), as quoted in The Selected Works of Thaddeus Stevens http://books.google.com/books?id=A0Fs655TKfsC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false.

Context: There can be no fanatics in the cause of genuine liberty. Fanaticism is excessive zeal. There may be, and have been fanatics in false religion – in the bloody religions of the heathen. There are fanatics in superstition. But there can be no fanatic, however warm their zeal, in the true religion, even although you sell your goods and bestow your money on the poor, and go on and follow your Master. There may, and every hour shows around me, fanatics in the cause of false liberty – that infamous liberty which justifies human bondage, that liberty whose ‘corner-stone is slavery.’ But there can be no fanaticism however high the enthusiasm, in the cause of rational, universal liberty – the liberty of the Declaration of Independence.

Address at the opening of the Exhibit on the World's Religions at Santa Clara University (31 March 2005) note: Elaborations and extensions of this declaration occur in Küng's later writings, including: There will be no peace among the nations without peace among the religions. There will be no peace among the religions without dialogue among the religions. There will be no dialogue among the religions without global ethical standards. There will therefore be no survival of this globe without a global ethic.

Context: The plain fact is that men's minds are built, as has been often said, in water-tight compartments. Religious after a fashion, they yet have many other things in them beside their religion, and unholy entanglements and associations inevitably obtain. The basenesses so commonly charged to religion's account are thus, almost all of them, not chargeable at all to religion proper, but rather to religion's wicked practical partner, the spirit of corporate dominion. And the bigotries are most of them in their turn chargeable to religion's wicked intellectual partner, the spirit of dogmatic dominion, the passion for laying down the law in the form of an absolutely closed-in theoretic system. The ecclesiastical spirit in general is the sum of these two spirits of dominion.
