The most certain test by which we judge whether a country is really free is the amount of security enjoyed by minorities - John Emerich Edward Dalberg-Acton

Opinions alter, manners change, creeds rise and fall, but the moral law is written on the tablets of eternity.

The political and intellectual orders remain permanently distinct from the spiritual. They follow their own ends, they obey their own laws, and in doing so they support the cause of religion by the discovery of truth and the upholding of right. They render this service by fulfilling their own ends independently and unrestrictedly, not by surrendering them for the sake of spiritual interests. Whatever diverts government and science from their own spheres, or leads religion to usurp their domains, confounds distinct authorities, and imperils not only political right and scientific truths, but also the cause of faith and morals. A government that, for the interests of religion, disregards political right, and a science that, for the sake of protecting faith, wavers and dissembles in the pursuit of knowledge, are instruments at least as well adapted to serve the cause of falsehood as to combat it, and never can be used in furtherance of the truth without that treachery to principle which is a sacrifice too costly to be made for the service of any interest whatever.

Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority, still more when you superadd the tendency or the certainty of corruption by authority. There is no worse heresy than that the office sanctifies the holder of it.
