Knowledge is an excellent drug; but no drug has virtue enough to preserve itself from corruption and decay, if the vessel be tainted and impure wherein it is put to keep.
Michel de MontaigneIn the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.
Michel de Montaigne
