William Gilbert (astronomer)

"Gilbert... repeatedly asserts the paramount value of experiments. He himself, no doubt, acted up to his own precepts; for his work contains all the fundamental facts of the science [of magnetism], so fully examined, indeed, that even at this day we have little to add to them."

"Gilbert, in his work, De Magnete printed in 1600 has only some vague notions that the magnetic virtue of the earth in some way determines the direction of the earths axis, the rate of its diurnal rotation, and that of the revolution of the moon about it. Gilbert died in 1603, and in his posthumous work (De Mundo nostro Sublunari Philosophia nova, 1631) we have already a more distinct statement of the attraction of one body by another. "The force which emanates from the moon reaches to the earth, and, in like manner, the magnetic virtue of the earth pervades the region of the moon: both correspond and conspire by the joint action of both, according to a proportion and conformity of motions, but the earth has more effect in consequence of its superior mass; the earth attracts and repels, the moon, and the moon within certain limits, the earth; not so as to make the bodies come together, as magnetic bodies do, but so that they may go on in a continuous course." Though this phraseology is capable of representing a good deal of the truth, it does not appear to have been connected... with any very definite notions of mechanical action in detail."

"The "New Philosophy" [De Mundo Nostro Sublunari Philosophia Nova] of Gilbert came to be published half a century after his death in the following curious circumstances. Within the period of apparently some two years after his demise, William Gilbert, of Melford, his elder brother, bearing, oddly enough, the same name... found, among Gilberts scattered papers, the fragmentary New Philosophy and the Meteorology. These (as he says, being governed by fraternal affection, as well as by an appreciation of the importance of the arguments advanced, whereof he felt unwilling to deprive the world), he arranged, caused to be translated into Latin, and prefixed to them a dedication... That he intended to publish the book is clear; nevertheless, he departed, as its author had done with his purpose unfulfilled."

"In 1626 Bacon succumbed to the results of his ill timed experiment in preserving chickens with snow... The Bacon manuscripts were sent to [Sir William] Boswells residence at the Hague, and there lay until Boswell, who died in 1647, confided them to the editorial care of Isaac Gruter who... published them all together in 1653. Among the papers which thus came into his hands, Gruter found the two manuscripts of William Gilbert, of Colchester, which William Gilbert, of Melford, had prepared, and these he edited and issued... in 1651."

"Only on the superficies of the globes is plainly seen the host of souls and of animate existences, and their great and delightful diversity the Creator taketh pleasure"

"Neither in any if the stars, nor in the sun, nor in the planets that are most operant in the world, can organs be disntinguished or imagined by us; nevertheless, they live and endow with life small bodies at the earths elevated points. If there is aught of which man may boast, that of a surety is soul, is mind; and the other animals, too, are ennobled by soul; even God, by whose rod all things are governed, is soul."
