"We have also sound houses, where we practice and demonstrate all sounds and their generation. We have harmonies which you have not, of quarter sounds and lesser slides of sounds. Divers instruments of music likewise to you unknown, some sweeter than any you have; together with bells and rings that are dainty and sweet. We represent small sounds as great and deep; likewise divers trembling and warblings of sounds, which in their original are entire. We represent and imitate all articulate sounds and letters, and the voices of beasts and birds. We have certain helps which set to the ear to do further the hearing greatly. We have also divers strange and artificial echoes, reflecting the voice many times, and as if it were tossing it; and some that give back the voice louder than it came, some shriller and some deeper; yea, some rendering the voice, differing in the letters or articulate sound from that they receive. We have also means to convey sounds in tubes and pipes, in strange lines and distances..."

“I confess that I have as vast contemplative ends, as I have moderate civil ends: for I have taken all knowledge to be my province; and if I could purge it of two sorts of rovers, whereof the one with frivolous disputations, confutations, and verbosities, the other with blind experiments and auricular traditions and impostures, hath committed so many spoils, I hope I should bring in industrious observations, grounded conclusions, and profitable inventions and discoveries; the best state of that province. This, whether it be curiosity, or vainglory, or nature, or (if one take it favourably) philanthropia, is so fixed in my mind as it cannot be removed. And I do easily see, that place of any reasonable countenance doth bring commandment of more wits than of a man's own; which is the thing I greatly affect.”

“The law of nature teaches me to speak in my own defence: With respect to this charge of bribery I am as innocent as any man born on St. Innocents Day. I never had a bribe or reward in my eye or thought when pronouncing judgment or order (…). I am ready to make an oblation of myself to the King. (17 April 1621)”

“He that defers his charity 'till he is dead, is (if a man weighs it rightly) rather liberal of another man's, than of his own.”

“Ne mireris, si vulgus verius loquatur quam honoratiores; quia etiam tutius loquitur.”

“I bequeath my soul to God (…). My body to be buried obscurely. For my name and memory, I leave it to men's charitable speeches, and to foreign nations, and the next age.”

“Credulity in arts and opinions (…) is likewise of two kinds viz., when men give too much belief to arts themselves, or to certain authors in any art. The sciences that sway the imagination more than the reason are principally three viz., astrology, natural magic, and alchemy (…). Alchemy may be compared to the man who told his sons that he had left them gold, buried somewhere in his vineyard; while they by digging found no gold, but by turning up the mould about the roots of the vines procured a plentiful vintage. So the search and endeavours to make gold have brought many useful inventions to light.”
