“The slaving Poor are incapable of any Principles: Gentlemen may be converted to true Principles, by Time and Experience. The middling Rank of Men have Curiosity and Knowledge enough to form Principles, but not enough to form true ones, or correct any Prejudices that they may have imbib’d: And ’tis among the middling Rank, that Tory Principles do at present prevail most in England.”

A similar statement apparently derived from this version has become widely attributed to Herbert Spencer, but there are no records of Spencer ever saying or writing it, the first known attributions to him occurring in 1922 as the epigraph to Le Roy Campbell's The True Function of Relaxation in Piano Playing: A Treatise on the Psycho-Physical Aspect of Piano Playing, With Exercises for Acquiring Relaxation: https://books.google.com/books?id=gjMuAAAAYAAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false "There is a principle which is a bar against all information, which is proof against all argument and which cannot fail to keep a man in everlasting ignorance!

Context: Mysticism intends a state of "possession," not action, and the individual is not a tool but a "vessel" of the divine. Action in the world must thus appear as endangering the absolutely irrational and other-worldly religious state. Active asceticism operates within the world; rationally active asceticism, in mastering the world, seeks to tame what is creatural and wicked through work in a worldly "vocation" (inner-worldly asceticism). Such asceticism contrasts radically with mysticism, if the latter draws the full conclusion of fleeing from the world (contemplative flight from the world). The contrast is tempered, however, if active asceticism confines itself to keeping down and to overcoming creatural wickedness in the actor's own nature. For then it enhances the concentration on the firmly established God-willed and active redemptory accomplishments to the point of avoiding any action in the orders of the world (asceticist flight from the world). Thereby active asceticism in external bearing comes close to contemplative flight from the world. The contrast between asceticism and mysticism is also tempered if the contemplative mystic does not draw the conclusion that he should flee from the world, but, like the inner-worldly asceticist, remain in the orders of the world (inner-worldly mysticism).
In both cases the contrast can actually disappear in practice and some combination of both forms of the quest for salvation may occur. But the contrast may continue to exist even under the veil of external similarity. For the true mystic the principle continues to hold: the creature must be silent so that God may speak.

Context: Principles are universal — that is, they transcend culture and geography. They're also timeless, they never change — principles such as fairness, kindness, respect, honesty, integrity, service, contribution. Different cultures may translate these principles into different practices and over time may even totally obscure these principles through the wrongful use of freedom. Nevertheless, they are present. Like the law of gravity, they operate constantly.
