“La historia de la electricidad es un campo lleno de agradables objetos, de acuerdo con todos los principios genuinos y universales del gusto, deducidos a partir de un conocimiento de la naturaleza humana.”

“Es sabido por todas las personas versadas en la filosofía experimental, que hay muchas pequeñas atenciones y precauciones necesarias que deben ser observadas en la realización de experimentos, que no se pueden describir con palabras, pero que es necesario describir, ya que la práctica las sugiere necesariamente, sin embargo, como todas las otras artes en las que se hacen uso de las manos y los dedos, es sólo la práctica frecuente la que puede permitir a una persona realizar experimentos complejos, de este o de cualquier tipo, con facilidad y prontitud.”

“Si mis escritos, en general, han sido útiles para mis contemporáneos, espero que estas memorias no caigan en saco rato para los que puedan venir detrás de mí, y especialmente en cuanto a la promoción de la virtud y la piedad, que, espero que yo pueda decirlo, he procurado practicar, y he tratado de inculcar a los demás.”

“Consideremos que toda la filosofía, aunque esté diversificada, no es más que una; siendo una con un mismo esquema general, que todos los filósofos, de todas las edades y naciones, han estado llevando a cabo, desde el principio del mundo. Aun siendo la misma labor, los trabajos de uno no sólo son análogos a los de otro, sino de forma inmediata subordinados a ellos… En este caso, un conocimiento íntimo de lo que se ha hecho antes que nosotros, no puede sino facilitar enormemente nuestro futuro progreso, si no es absolutamente necesario para ello.”

“La mente del hombre nunca puede ser totalmente estéril. A través de toda nuestra vida, estamos sujetos a impresiones sucesivas, porque, o bien las nuevas ideas están fluyendo continuamente, o las huellas de las antiguas se marcan más profundamente. Si, por lo tanto, no estáis adquiriendo buenos principios, estáis seguro de que están adquiriendo los malos, si no forjáis hábitos virtuosos… estaréis forjando malos vicios.”

Joseph Priestley: Frases en inglés

“I am sorry… to have occasion to admonish Mr. Gibbon, that he should have distinguished better than he has done between christianity itself, and the corruptions of it. …He should not have taken it for granted, that the doctrine of three persons in one God, or the doctrine of atonement for the sins of all mankind, by the death of one man, were any parts of the christian system; when, if he had read the New Testament for himself, he must have seen the doctrine of the proper unity of God, and also that of his free mercy to the penitent, in almost every page of it.”

“All hereditary Government is in its nature tyranny. An heritable crown, or an heritable throne, or by what other fanciful name such things may be called, have no other significant explanation than that mankind are heritable property. To inherit a Government, is to inherit the people, as if they were flocks and herds.”

“It is sufficiently evident from many circumstances, that the doctrine of the divinity of Christ did not establish itself without much opposition, especially from the unlearned among the Christians, who thought that it savoured of Polytheism, that it was introduced by those who had had a philosophical education, and was by degrees adopted by others, on account of its covering the great offence of the cross, by exalting the personal dignity of our Saviour.”

“If any person, discouraged by these difficulties, should think to relieve himself by rejecting all religion, natural and revealed, he will find, if he reflect at all, that he has miserably deceived himself, and that he is involved in greater perplexity than ever; the scheme he has adopted not only filling his mind with great darkness and distress, but being contrary to some of the plainest appearances in nature, and therefore manifestly irrational and absurd.”

“And since every man retains, and can never be deprived of his natural right (founded on a regard to the general good) of relieving himself from all oppression, that is, from every thing that has been imposed upon him without his own consent; this must be the only true and proper foundation of all the governments subsisting in the world, and that to which the people who compose them have an unalienable right to bring them back.”

“The friends of genuine, and I will add of rational Christianity, have not, however, on the whole, much reason to regret that their enemies have not made these distinctions; since by this means, we have been taught to make them ourselves; so that Christianity is perhaps as much indebted to its enemies, as to its friends, for this important service. In their indiscriminate attacks, whatever has been found to be untenable has been gradually abandoned, and I hope the attack will be continued till nothing of the wretched outworks be left; and then, I doubt not, a safe and impregnable fortress, will be sound in the center, a fortress built upon a rock, against which the gates of death will not prevail.”

“Contemporary with Vitellio and Peccam was… Roger Bacon, a man of almost universal genius, and who wrote on almost every branch of science. He frequently quotes Alhazen on the subject of optics, and seems to have carefully studied his writings, as well as those of other Arabians, which were the fountains of natural knowledge in those days, and which had been introduced into Europe by means of the Moors in Spain. Notwithstanding the pains this great man took with the subject of opticks, it does not appear that, with respect to theory, he made any considerable advance upon what Alhazen had done before him.”

“For the government of the temporary magistrates of a democracy, or even the laws themselves may be as tyrannical as the maxims of the most despotic monarchy, and the administration of the government may be as destructive of private happiness. The only consolation that a democracy suggests in those circumstances is, that every member of the state has a chance of arriving at a share in the chief magistracy, and consequently of playing the tyrant in his turn; and as there is no government in the world so perfectly democratical, as that every member of the state, without exception, has a right of being admitted into the administration, great numbers will be in the same condition as if they had lived under the most absolute monarchy; and this is, in fact, almost universally the case with the poor, in all governments.”

“[The doctrine of air] I was led into in consequence of inhabiting a house adjoining to a public brewery, where I at first amused myself with making experiments on the fixed air [carbon dioxide] which I found ready made in the process of fermentation. When I removed from that house I was under the necessity of making the fixed air for myself; and one experiment leading to another, as I have distinctly and faithfully noted in my various publications on the subject, I by degrees contrived a convenient apparatus for the purpose, but of the cheapest kind.”

Letter to Dr. Price (Oct. 19, 1771) as quoted in John Towill Rutt, Life and Correspondence of Joseph Priestley http://books.google.com/books?id=psMGAAAAQAAJ (1831)

“Indeed, if any man can say, that it is not an interesting question, whether his existence terminate at death, or is to be resumed at a future period, and then to continue for ever, he must be of a low and abject mind. To a rational being, capable of contemplating the wonders of nature, and of investigating the laws of it, and to a being of a social disposition, his existence, and the continuance of his rational faculties, must be an object of unspeakable value to him; and consequently he must ardently wish that christianity… may be true. For to a philosopher, who forms his judgment by what he actually observes, the doctrine of soul, capable of subsisting and acting when the body is in the grave, will never give any satisfaction. To every person, therefore, who is capable of enjoying his existence, the christian doctrine of a resurrection opens a glorious and transporting prospect.”

“Mr. Gibbon has much to learn concerning the gospel before he can be properly qualified to write against it. Hitherto he seems to have been acquainted with nothing but the corrupt establishments of what is very improperly called Christianity; whereas it is incumbent upon him to read and study the New Testament for himself. There he will find nothing like Platonism, but doctrines in every respect the reverse of that system of philosophy, which weak and undistinguishing christians afterwards incorporated with it.
Had Mr. Gibbon lived in France, Spain, or Italy, he might with the same reason have ranked the doctrine of transubstantiation, and the worship of saints and angels among the essentials of Christianity, as the doctrines of the trinity and of the atonement.”

“Man derives two capital advantages from the superiority of his intellectual powers. The first is, that, as an individual, he possesses a certain comprehension of mind, whereby he contemplates and enjoys the past and the future, as well as the present. This comprehension is enlarged with the experience of every day; and by this means the happiness of man, as he advances in intellect, is continually less dependent on temporary circumstances and sensations.The next advantage resulting from the same principle, and which is, in many respects, both the cause and effect of the former, is, that the human species itself is capable of a similar and unbounded improvement; whereby mankind in a later age are greatly superior to mankind in a former age, the individuals being taken at the same time of life.”
