“Then did they strive with emulation who should repeat most wise maxims importing the necessity of suspicion in the choice of our friends—such as “mistrust is the mother of security,” with many more to the same effect.... But notwithstanding the esteem which they professed for suspicion, yet did they think proper to veil it under the name of caution.”

“The worthiest man to be known, and for a pattern to be presented to the world, he is the man of whom we have most certain knowledge. He hath been declared and enlightened by the most clear-seeing men that ever were; the testimonies we have of him are in faithfulness and sufficiency most admirable.”
—Michel de Montaigne (1533–1592)
