In the system of Copernicus there are found many and great inconveniences; for both the loading of the earth with triple motion is very incommodious, and the separation of the sun from the company of the planets, with which it has so many passions in common, is likewise a difficulty, and the introduction of so much immobility into nature, by representing the sun and stars as immovable, especially being of all bodies the highest and most radiant, and making the moon revolve about the earth in an epicycle, and some other assumptions of his, are the speculations of one who cares not what fictions he introduces into nature, provided his calculations answer. But if it be granted that the earth moves, it would seem more natural to suppose that there is no system at all, but scattered globes (…) than to constitute a system of which the sun is the centre. And this the consent of ages and of antiquity has rather embraced and approved. For the opinion concerning the motion of the earth is not new, but revived from the ancients (…) whereas the opinion that the sun is the centre of the world and immovable is altogether new (…) and was first introduced by Copernicus. (…) But if the earth moves, the stars may either be stationary, as Copernicus thought or, as it is far more probable, and has been suggested by Gilbert, they may revolve each round its own centre in its own place, without any motion of its centre, as the earth itself does (…). But either way, there is no reason why there should not be stars above stars til they go beyond our sight.

Death is a friend of ours; and he that is not ready to entertain him is not at home.

It is true that may hold in these things, which is the general root of superstition; namely, that men observe when things hit, and not when they miss; and commit to memory the one, and forget and pass over the other.

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 distance (…).

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.

Riches are a good handmaid, but the worst mistress.

Lucid intervals and happy pauses.

For I find that even those that have sought knowledge for itself and not for benefit, or ostentation, or any practical enablement in the course of their life, have nevertheless propounded to themselves a wrong mark, namely, satisfaction, which men call truth, and not operation. For as in the courts and services of princes and states, it is a much easier matter to give satisfaction than to do the business; so in the inquiring of causes and reasons it is much easier to find out such causes as will satisfy the mind of man, and quiet objections, than such causes as will direct him and give him light to new experiences and inventions.

Knowledge, that tendeth but to satisfaction, is but as a courtesan, which is for pleasure, and not for fruit or generation.
