Joseph Priestley Quotes

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.

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.

The History of Electricity is a field full of pleasing objects, according to all the genuine and universal principles of taste, deduced from a knowledge of human nature. Scenes like these, in which we see a gradual rise and progress in things, always exhibit a pleasing spectacle to the human mind. Nature, in all her delightful walks, abounds with such views, and they are in a more especial manner connected with every thing that relates to human life and happiness; things, in their own nature, the most interesting to us. Hence it is, that the power of association has annexed crowds of pleasing sensations to the contemplation of every object, in which this property is apparent. This pleasure, likewise, bears a considerable resemblance to that of the sublime, which is one of the most exquisite of all those that affect the human imagination. For an object in which we see a perpetual progress and improvement is, as it were, continually rising in its magnitude; and moreover, when we see an actual increase, in a long period of time past, we cannot help forming an idea of an unlimited increase in futurity; which is a prospect really boundless, and sublime.

It is the earnest wish of my heart, that your minds may be well established in the sound principles of religious knowledge, because I am fully persuaded, that nothing else can be a sufficient foundation of a virtuous and truly respectable conduct in life, or of good hope in death. A mind destitute of knowledge (and, comparatively speaking, no kind of knowledge, besides that of religion, deserves the name) is like a field on which no culture has been bestowed, which, the richer it is, the ranker weeds it will produce, If nothing good be sown in it, it will be dccupied by plants that are useless or noxious.

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.<p>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.

Respect a parliamentary king, and chearfully pay all parliamentary taxes; but have nothing to do with a parliamentary religion, or a parliamentary God. Religious rights, and religious liberty, are things of inestimable value. For these have many of our ancestors suffered and died; and shall we, in the sunshine of prosperity, desert that glorious cause, from which no storms of adversity or persecution could make them swerve? Let us consider if as a duty of the first rank with respect to moral obligation, to transmit to our posterity, and provide, as far as we can, for transmitting, unimpaired, to the latest generations, that generous zeal for religion and liberty, which makes the memory of our forefathers so truly illustrious.

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.

In his Opus Majus he demonstrates, that if a transparent body, interposed between the eye and an object, be convex towards the eye, the object will appear magnified. This observation our author certainly had from Alhazen... this writer [Bacon] gives us figures, representing the progress of rays of light through his spherical segment, as well as endeavours to give reasons why objects are magnified... From the writings of Alhazen and these observations and experiments of Bacon together, it is not improbable that some monks gradually hit upon the construction of spectacles, to which Bacon's lesser segment, not withstanding his mistake concerning it, was a nearer approach than Alhazen's... Whoever they were that pursued the discoveries of Bacon, they probably observed, that a very small convex glass, when held at a greater distance from a book, would magnify the letters more than when it was placed close to them, in which position only Bacon seemed to have used it. In the next place, they might try whether two of these small segments of a sphere placed together, or a glass convex on both sides, would not magnify more than one of them. They would then find, that two of these glasses, one for each eye, would answer the purpose of reading better than one; and lastly they might find, that different degrees of convexity, suited different persons. It is certain that spectacles were well known in the 13th century, and not long before. ...It would certainly have been a great satisfaction to us to have been able to trace the actual steps in the progress of this most useful invention, without which most persons who have a taste for reading must have had the melancholy prospect of passing a very dull and joyless old age; and must have been deprived of the pleasure of entertaining themselves by conversing with the absent and the dead, when they were no longer capable of acting their part among the living. Telescopes and microscopes are to be numbered among the superfluities of life when compared to spectacles, which may now be ranked almost among the necessities of it; since the arts of reading and writing are almost universal.

Too many christians have been chargeable with... confounding the Logos of Plato with that of John, and making of it a second person in the trinity, than which no two things can be more different.

The history of philosophy enjoys, in some measure, the advantages both of civil and natural history, whereby it is relieved from what is most tedious and disgusting in both. Philosophy exhibits the powers of nature, discovered and directed by human art. It has, therefore, in some measure, the boundless variety with the amazing uniformity of the one, and likewise every thing that is pleasing and interesting in the other. And the idea of continual rise and improvement is conspicuous in the whole study, whether we be attentive to the part which nature, or that which men are acting in the great scene. It is here that we see the human understanding to its greatest advantage, grasping at the noblest objects, and increasing its own powers, by acquiring to itself the powers of nature, and directing them to the accomplishment of its own views; whereby the security, and happiness of mankind are daily improved. Human abilities are chiefly conspicuous in adapting means to ends, and in deducing one thing from another by the method of analogy; and where may we find instances of greater sagacity, than in philosophers diversifying the situations of things, in order to give them an opportunity of showing their mutual relations, affections, and influences; deducing one truth and one discovery from another, and applying them all to the useful purposes of human life. If the exertion of human abilities, which cannot but form a delightful spectacle for the human imagination, give us pleasure, we enjoy it here in a higher degree than while we are contemplating the schemes of warriors, and the stratagems of their bloody art.

The unity of God is a doctrine on which the greatest stress is laid in the whole system of revelation. To guard this most important article was the principal object of the Jewish religion; and, notwithstanding the proneness of the Jews to idolatry, at length it fully answered its purpose in reclaiming them, and in impressing the minds of many persons of other nations in favour of the same fundamental truth. The Jews were taught by their prophets to expect a Messiah, who was to be descended from the tribe of Judah, and the family of David, — a person in whom themselves and all the nations of the earth should be blessed; but none of their prophets gave them an idea of any other than a man like themselves in that illustrious character, and no other did they ever expect, or do they expect to this day. Jesus Christ, whose history answers to the description given of the Messiah by the prophets, made no other pretensions; referring all his extraordinary power to God, his Father, who, he expressly says, spake and acted by him, and who raised him from the dead: and it is most evident that the apostles, and all those who conversed with our Lord before and after his resurrection, considered him in no other light than simply as "a man approved of God, by wonders and signs which God did by him."

Whenever our Lord speaks of the object of his mission and death, as he often does, it is either in a more general way, as for the salvation of the world, to do the will of God, to fulfil the scripture prophecies … or more particularly, to give the fullest proof of his mission by his resurrection from the dead, and an assurance of a similar resurrection of all his followers. He also compares his being raised upon the cross to the elevation of the serpent in the wilderness, and to seed buried in the ground, as necessary to its future increase. But all these representations are quite foreign to anything in the doctrine of atonement.

It is no use speaking in soft, gentle tones if everyone else is shouting.

Most of the early Christian writers thought the text "I and my Father are one," was to be understood of an unity or harmony of disposition only. Thus Tertullian observes, that the expression is unum, one thing, not one person; and he explains it to mean unity, likeness, conjunction, and of the love that the Father bore to the Son. Origen says, "let him consider that text, 'all that believed were of one heart and of one soul,' and then he will understand this, 'I and my Father are one.'"

Our anxiety during the King of France's escape, and our joy on his capture, cannot be described. I hope the new constitution is now effectually established, and that all attempts to overturn it will be in vain. The high-party here are mortified in the extreme. They would have had France involved in a most ruinous civil war, for the imaginary rights of one man. A majority, I fear, of Englishmen are in these sentiments, so that we are far indeed behind the French. In spite of all we can write or do, an attachment to high maxims of government gains ground here, and the love of liberty is on the decline. Such is the influence of the court. Nothing but public difficulties will open our eyes.
