Give you a reason on compulsion! if reasons were as plentiful as black — Reason

"Reason is omnivorous; it does not pasture exclusively in scientific fields."

"REASON, v.i. To weight probabilities in the scales of desire."

"Reason may be employed in two ways to establish a point: firstly, for the purpose of furnishing sufficient proof of some principle, as in natural science, where sufficient proof can be brought to show that the movement of the heavens is always of uniform velocity. Reason is employed in another way, not as furnishing a sufficient proof of a principle, but as confirming an already established principle, by showing the congruity of its results, as in astrology the theory of eccentrics and epicycles is considered as established, because thereby the sensible appearances of the heavenly movements can be explained; not, however, as if this proof were sufficient, forasmuch as some other theory might explain them."

"While we [philosophers] study with attention the vanity of life... we are, perhaps, all the while flattering our natural indolence, which, hating the bustle of the world, and drudgery of business, seeks a pretense of reason to give itself a full and uncontrolled indulgence."

"Reason always stands in need of being purified by faith"

"Copernicanism and other "rational" views exist today only because reason was overruled at some time in their past. (The opposite is also true: witchcraft and other "irrational" views had ceased to be influential only because reason was overruled at some time in their past.)"
